The State Of Identity Management in 2015
Constellation Research recently launched the "State of Enterprise Technology" series of research reports. These assess the current enterprise innovations which Constellation considers most crucial to digital transformation, and provide snapshots of the future usage and evolution of these technologies.
My second contribution to the state-of-the-state series is "Identity Management Moves from Who to What". Here's an excerpt from the report:
In spite of all the fuss, personal identity is not usually important in routine business. Most transactions are authorized according to someone’s credentials, membership, role or other properties, rather than their personal details. Organizations actually deal with many people in a largely impersonal way. People don’t often care who someone really is before conducting business with them. So in digital Identity Management (IdM), one should care less about who a party is than what they are, with respect to attributes that matter in the context we’re in. This shift in focus is coming to dominate the identity landscape, for it simplifies a traditionally multi-disciplined problem set. Historically, the identity management community has made too much of identity!
Six Digital Identity Trends for 2015
1. Mobile becomes the center of gravity for identity. The mobile device brings convergence for a decade of progress in IdM. For two-factor authentication, the cell phone is its own second factor, protected against unauthorized use by PIN or biometric. Hardly anyone ever goes anywhere without their mobile - service providers can increasingly count on that without disenfranchising many customers. Best of all, the mobile device itself joins authentication to the app, intimately and seamlessly, in the transaction context of the moment. And today’s phones have powerful embedded cryptographic processors and key stores for accurate mutual authentication, and mobile digital wallets, as Apple’s Tim Cook highlighted at the recent White House Cyber Security Summit.
2. Hardware is the key – and holds the keys – to identity. Despite the lure of the cloud, hardware has re-emerged as pivotal in IdM. All really serious security and authentication takes place in secure dedicated hardware, such as SIM cards, ATMs, EMV cards, and the new Trusted Execution Environment mobile devices. Today’s leading authentication initiatives, like the FIDO Alliance, are intimately connected to standard cryptographic modules now embedded in most mobile devices. Hardware-based identity management has arrived just in the nick of time, on the eve of the Internet of Things.
3. The “Attributes Push” will shift how we think about identity. In the words of Andrew Nash, CEO of Confyrm Inc. (and previously the identity leader at PayPal and Google), “Attributes are at least as interesting as identities, if not more so.” Attributes are to identity as genes are to organisms – they are really what matters about you when you’re trying to access a service. By fractionating identity into attributes and focusing on what we really need to reveal about users, we can enhance privacy while automating more and more of our everyday transactions.
The Attributes Push may recast social logon. Until now, Facebook and Google have been widely tipped to become “Identity Providers”, but even these giants have found federated identity easier said than done. A dark horse in the identity stakes – LinkedIn – may take the lead with its superior holdings in verified business attributes.
4. The identity agenda is narrowing. For 20 years, brands and organizations have obsessed about who someone is online. And even before we’ve solved the basics, we over-reached. We've seen entrepreneurs trying to monetize identity, and identity engineers trying to convince conservative institutions like banks that “Identity Provider” is a compelling new role in the digital ecosystem. Now at last, the IdM industry agenda is narrowing toward more achievable and more important goals - precise authentication instead of general identification.
5. A digital identity stack is emerging. The FIDO Alliance and others face a challenge in shifting and improving the words people use in this space. Words, of course, matter, as do visualizations. IdM has suffered for too long under loose and misleading metaphors. One of the most powerful abstractions in IT was the OSI networking stack. A comparable sort of stack may be emerging in IdM.
6. Continuity will shape the identity experience. Continuity will make or break the user experience as the lines blur between real world and virtual, and between the Internet of Computers and the Internet of Things. But at the same time, we need to preserve clear boundaries between our digital personae, or else privacy catastrophes await. “Continuous” (also referred to as “Ambient”) Authentication is a hot new research area, striving to provide more useful and flexible signals about the instantaneous state of a user at any time. There is an explosion in devices now that can be tapped for Continuous Authentication signals, and by the same token, rich new apps in health, lifestyle and social domains, running on those very devices, that need seamless identity management.
A snapshot at my report "Identity Moves from Who to What" is available for download at Constellation Research. It expands on the points above, and sets out recommendations for enterprises to adopt the latest identity management thinking.
I have just updated my periodic series of researh reports on the FIDO Alliance. The fourth report, "FIDO Alliance Update: On Track to a Standard" will be available at Constellation Research shortly
The Identity Management industry leader publishes its protocol specifications at v1.0, launches a certification program, and attracts support in Microsoft Windows 10.
The FIDO Alliance is the fastest-growing Identity Management (IdM) consortium we have seen. Comprising technology vendors, solutions providers, consumer device companies, and e-commerce services, the FIDO Alliance is working on protocols and standards to strongly authenticate users and personal devices online. With a fresh focus and discipline in this traditionally complicated field, FIDO envisages simply “doing for authentication what Ethernet did for networking”.
Launched in early 2013, the FIDO Alliance has now grown to over 180 members. Included are technology heavyweights like Google, Lenovo and Microsoft; almost every SIM and smartcard supplier; payments giants Discover, MasterCard, PayPal and Visa; several banks; and e-commerce players like Alibaba and Netflix.
FIDO is radically different from any IdM consortium to date. We all know how important it is to fix passwords: They’re hard to use, inherently insecure, and lie at the heart of most breaches. The Federated Identity movement seeks to reduce the number of passwords by sharing credentials, but this invariably confounds the relationships we have with services and complicates liability when more parties rely on fewer identities.
In contrast, FIDO’s mission is refreshingly clear: Take the smartphones and devices most of us are intimately connected to, and use the built-in cryptography to authenticate users to services. A registered FIDO-compliant device, when activated by its user, can send verified details about the device and the user to service providers, via standardized protocols. FIDO leverages the ubiquity of sophisticated handsets and the tidal wave of smart things. The Alliance focuses on device level protocols without venturing to change the way user accounts are managed or shared.
The centerpieces of FIDO’s technical work are two protocols, called UAF and U2F, for exchanging verified authentication signals between devices and services. Several commercial applications have already been released under the UAF and U2F specifications, including fingerprint-based payments apps from Alibaba and PayPal, and Google’s Security Key from Yubico. After a rigorous review process, both protocols are published now at version 1.0, and the FIDO Certified Testing program was launched in April 2015. And Microsoft announced that FIDO support would be built into Windows 10.
With its focus, pragmatism and membership breadth, FIDO is today’s go-to authentication standards effort. In this report, I look at what the FIDO Alliance has to offer vendors and end user communities, and its critical success factors.
I'm going to assume readers know what's meant by the "Creepy Test" in privacy. Here's a short appeal to use the Creepy Test sparingly and carefully.
The most obvious problem with the Creepy Test is its subjectivity. One person's "creepy" can be another person's "COOL!!". For example, a friend of mine thought it was cool when he used Google Maps to check out a hotel he was going to, and the software usefully reminded him of his check-in time (evidently, Google had scanned his gmail and mashed up the registration details next time he searched for the property). I actually thought this was way beyond creepy; imagine if it wasn't a hotel but a mental health facility, and Google was watching your psychiatric appointments.
In fact, for some people, creepy might actually be cool, in the same way as horror movies or chilli peppers are cool. There's already an implicit dare in the "Nothing To Hide" argument. Some brave souls seem to brag that they haven't done anything they don't mind being made public.
Our sense of what's creepy changes over time. We can get used to intrusive technologies, and that suits the agendas of infomoplists who make fortunes from personal data, hoping that we won't notice. On the other hand, objective and technology-neutral data privacy principles have been with us for over thirty years, and by and large, they work well to address contemporary problems like facial recognition, the cloud, and augmented reality glasses.
Using folksy terms in privacy might make the topic more accessible to laypeople, but it tends to distract from the technicalities of data privacy regulations. These are not difficult matters in the scheme of things; data privacy is technically about objective and reasonable controls on the collection, use and disclosure of personally identifiable information. I encourage anyone with an interest in privacy to spend time familiarising themselves with common Privacy Principles and the definition of Personal Information. And then it's easy to see that activities like Facebook's automated face recognition and Tag Suggestions aren't merely creepy; they are objectively unlawful!
Finally and most insideously, when emotive terms like creepy are used in debating public policy, it actually disempowers the critical voices. If "creepy" is the worst thing you can say about a given privacy concern, then you're marginalised.
We should avoid being subjective about privacy. By all means, let's use the Creepy Test to help spot potential privacy problems, and kick off a conversation. But as quickly as possible, we need to reduce privacy problems to objective criteria and, with cool heads, debate the appropriate responses.
See also A Theory of Creepy: Technology, Privacy and Shifting Social Norms by Omer Tene and Jules Polonetsky.
- "Alas, intuitions and perceptions of 'creepiness' are highly subjective and difficult to generalize as social norms are being strained by new technologies and capabilities". Tene & Polonetsky.
Facial recognition is digital alchemy. It's the prince of data mining.
Facial recognition takes previously anonymous images and conjures peoples' identities. It's an invaluable capability. Once they can pick out faces in crowds, trawling surreptitiously through anyone and everyone's photos, the social network businesses can work out what we're doing, when and where we're doing it, and who we're doing it with. The companies figure out what we like to do without us having to 'like' or favorite anything.
So Google, Facebook, Apple at al have invested hundreds of megabucks in face recognition R&D and buying technology start-ups. And they spend billions of dollars buying images and especially faces, going back to Google's acquisition of Picasa in 2004, and most recently, Facebook's ill-fated $3 billion offer for Snapchat.
But if most people find face recognition rather too creepy, then there is cause for optimism. The technocrats have gone too far. What many of them still don't get is this: If you take anonymous data (in the form of photos) and attach names to that data (which is what Facebook photo tagging does - it guesses who people are in photos are, attaches putative names to records, and invites users to confirm them) then you Collect Personal Information. Around the world, existing pre-biometrics era black letter Privacy Law says you can't Collect PII even indirectly like that without am express reason and without consent.
When automatic facial recognition converts anonymous data into PII, it crosses a bright line in the law.
A repeated refrain of cynics and “infomopolists” alike is that privacy is dead. People are supposed to know that anything on the Internet is up for grabs. In some circles this thinking turns into digital apartheid; some say if you’re so precious about your privacy, just stay offline.
But socialising and privacy are hardly mutually exclusive; we don’t walk around in public with our names tattooed on our foreheads. Why can’t we participate in online social networks in a measured, controlled way without submitting to the operators’ rampant X-ray vision? There is nothing inevitable about trading off privacy for conviviality.
The privacy dangers in Facebook and the like run much deeper than the self-harm done by some peoples’ overly enthusiastic sharing. Promiscuity is actually not the worst problem, neither is the notorious difficulty of navigating complex and ever changing privacy settings.
The advent of facial recognition presents far more serious and subtle privacy challenges.
Facebook has invested heavily in face recognition technology, and not just for fun. Facebook uses it in effect to crowd-source the identification and surveillance of its members. With facial recognition, Facebook is building up detailed pictures of what people do, when, where and with whom.
You can be tagged without consent in a photo taken and uploaded by a total stranger.
The majority of photos uploaded to personal albums over the years were not intended for anything other than private viewing.
Under the privacy law of Australia and data protection regulations in dozens of other jurisdictions, what matters is whether data is personally identifiable. The Commonwealth Privacy Act 1988 (as amended in 2014) defines “Personal Information” as: “information or an opinion about an identified individual, or an individual who is reasonably identifiable”.
Whenever Facebook attaches a member’s name to a photo, they are converting hitherto anonymous data into Personal Information, and in so doing, they become subject to privacy law. Automated facial recognition represents an indirect collection of Personal Information. However too many people still underestimate the privacy implications; some technologists naively claim that faces are “public” and that people can have no expectation of privacy in their facial images, ignoring that information privacy as explained is about the identifiability and identification of data; the words “public” and “private” don’t even figure in the Privacy Act!
If a government was stealing into our photo albums, labeling people and profiling them, there would be riots. It's high time that private sector surveillance - for profit - is seen for what it is, and stopped.
A Social Media Week Sydney event #SMWSydney

Fri, Sep 26 - 10:00 AM - 11:30 AM
How can you navigate privacy fact and fiction, without the geeks and lawyers boring each other to death?
It's often said that technology has outpaced privacy law. Many digital businesses seem empowered by this brash belief. And so they proceed with apparent impunity to collect and monetise as much Personal Information as they can get their hands on.
But it's a myth!
Some of the biggest corporations in the world, including Google and Facebook, have been forcefully brought to book by privacy regulations. So, we have to ask ourselves:
- what does privacy law really mean for social media in Australia?
- is privacy "good for business"?
- is privacy "not a technology issue"?
- how can digital businesses navigate fact & fiction, without their geeks and lawyers boring each other to death?
In this Social Media Week Master Class I will:
- unpack what's "creepy" about certain online practices
- show how to rate data privacy issues objectively
- analyse classic misadventures with geolocation, facial recognition, and predicting when shoppers are pregnant
- critique photo tagging and crowd-sourced surveillance
- explain why Snapchat is worth more than three billion dollars
- analyse the regulatory implications of Big Data, Biometrics, Wearables and The Internet of Things.
We couldn't have timed this Master Class better, coming two weeks after the announcement of the Apple Watch, which will figure prominently in the class!
So please come along, for a fun and in-depth a look at social media, digital technology, the law, and decency.
About the presenter
Steve Wilson is a technologist, who stumbled into privacy 12 years ago. He rejected those well meaning slogans (like "Privacy Is Good For Business!") and instead dug into the relationships between information technology and information privacy. Now he researches and develops design patterns to help sort out privacy, alongside all the other competing requirements of security, cost, usability and revenue. His latest publications include:
- "Big Privacy: The new standard for Big Data Privacy" from Constellation Research, and
- "The collision between Big Data and privacy law" due out in October in the Australian Journal of Telecommunications and the Digital Economy.
The problem of identity takeover
The root cause of much identity theft and fraud today is the sad fact that customer reference numbers, personal identifiers and attributes generally are so easy to copy and replay without permission and without detection. Simple numerical attributes like bank account numbers and health IDs can be stolen from many different sources, and replayed with impunity in bogus transactions.
Our personal data nowadays is leaking more or less constantly, through breached databases, websites, online forms, call centres and so on, to such an extent that customer reference numbers on their own are no longer reliable. Privacy consequentially suffers because customers are required to assert their identity through circumstantial evidence, like name and address, birth date, mother’s maiden name and other pseudo secrets. All this data in turn is liable to be stolen and used against us, leading to spiraling identity fraud.
To restore the reliability of personal attribute data, we need to know their pedigree. We need to know that a presented data item is genuine, that it originated from a trusted authority, it’s been stored safely by its owner, and it’s been presented with the owner’s consent. If confidence in single attributes can be restored then we can step back from all the auxiliary proof-of-identity needed for routine transactions, and thus curb identity theft.
A practical response to ID theft
Several recent breaches of government registers leave citizens vulnerable to ID theft. In Korea, the national identity card system was attacked and it seems that all Korean's citizen IDs will have to be re-issued. In the US, Social Security Numbers are often stolen and used tin fraudulent identifications; recently, SSNs of 800,000 Post Office employees appear to have been stolen along with other personal records.
We could protect people against having their stolen identifiers used behind their backs. It shouldn't actually be necessary to re-issue every Korean's ID. Improvements may be made to the reliability of identification data without dramatically changing Relying Parties' backend processes. If for instance a service provider has always used SSN as part of its identification regime, they could continue to do so, if only the actual Social Security Numbers being received were reliable!
The trick is to be able to tell "original" ID numbers from "copies". But what does "original" even mean in the digital world? A more precise term for what we really want is pedigree. What we need is to be able to present attribute data in such a way that the receiver may be sure of their pedigree; that is, know that the attributes were originally issued by an authoritative body, that the data has been kept safe, and that each presentation of the attribute has occurred under the owner's control.
These objectives can be met with the help of smart cryptographic technologies which today are built into most smart phones and smartcards, and which are finally being properly exploited by initiatives like the FIDO Alliance.
"Notarising" attributes in chip devices
There are ways of issuing attributes to a smart chip device that prevent them from being stolen, copied and claimed by anyone else. One way to do so is to encapsulate and notarise attributes in a unique digital certificate issued to a chip. Today, a great many personal devices routinely embody cryptographically suitable chips for this purpose, including smart phones, SIM cards, "Secure Elements", smartcards and many wearable computers.
Consider an individual named Smith to whom Organisation A has issued a unique attribute N (which could be as simple as a customer reference number). If N is saved in ordinary computer memory or something like a magnetic stripe card, then it has no pedigree. Once the number N is presented by the cardholder in a transaction, it has the same properties as any other number. To better safeguard N in a chip device, it can be sealed into a digital certificate, as follows:
1. generate a fresh private-public key pair inside Smith’s chip
2. export the public key
3. create a digital certificate around the public key, with an attribute corresponding to N
4. have the certificate signed by (or on behalf of) organisation A.
The result of coordinating these processes and technologies is a logical triangle that inextricably binds cardholder Smith to their attribute N and to a specific personally controlled device. The certificate signed by organisation A attests to both Smith’s entitlement to N and Smith's control of a particular key unique to the device. Keys generated inside the chip are retained internally, never divulged to outsiders. It is not possible to copy the private key to another device, so the logical triangle cannot be reproduced or counterfeited.
Note that this technique lies at the core of the EMV "Chip-and-PIN" system where the smart payment card digitally signs cardholder and transaction data, rendering it immune to replay, before sending it to the merchant terminal. See also my 2012 paper Calling for a uniform approach to card fraud, offline and on. Now we should generalise notarised personal data and digitally signed transactions beyond Card-Present payments into as much online business as possible.
Restoring privacy and consumer control
When Smith wants to present their attribute N in an electronic transaction, instead of simply copying N out of memory (at which point it would lose its pedigree), Smith’s transaction software digitally signs the transaction using the certificate containing N. With standard security software, any third party can then verify that the transaction originated from a genuine chip holding the unique key certified by A as containing the attribute N.
Note that N doesn't have to be a customer number or numeric identifier; it could be any personal data, such as a biometric template, or a package of medical information like an allergy alert, or an interesting isolated (and anonymous) property of the user such as their age.
The capability to manage multiple key pairs and certificates, and to sign transactions with a nominated private key, is increasingly built into smart devices today. By narrowing down what you need to know about someone to a precise attribute or personal data item, we will reduce identity theft and fraud while radically improving privacy. This sort of privacy enhancing technology is the key to a safe Internet of Things, and fortunately now is widely available.
Addressing ID theft
Perhaps the best thing governments could do immediately is to adopt smartcards and equivalent smart phone apps for holding and presenting such attributes as official ID numbers. The US government has actually come close to such a plan many times; Chip-based Social Security Cards and Medicare Cards have been proposed before, without realising their full potential. These devices would best be used as above to hold a citizen's identifiers and present them cryptographically, without vulnerability to ID theft and takeover. We wouldn't have to re-issue compromised SSNs; we would instead switch from manual presentation of these numbers to automatic online presentation, with a chip card or smart phone app conveying the data through digitally signatures.
First Day Reflections from CIS Monterey.
Follow along on Twitter at #CISmcc (for the Monterey Conference Centre).
The Cloud Identity Summit really is the top event on the identity calendar. The calibre of the speakers, the relevance and currency of the material, the depth and breadth of the cohort, and the international spread are all unsurpassed. It's been great to meet old cyber-friends in "XYZ Space" at last -- like Emma Lindley from the UK and Lance Peterman. And to catch up with such talented folks like Steffen Sorensen from New Zealand once again.
A day or two before, Ian Glazer of Salesforce asked in a tweet what we were expecting to get out of CIS. And I replied that I hoped to change my mind about something. It's unnerving to have your understanding and assumptions challenged by the best in the field ... OK, sometimes it's outright embarrassing ... but that's what these events are all about. A very wise lawyer said to me once, around 1999 at the dawn of e-commerce, that he had changed his mind about authentication a few times up to that point, and that he fully expected to change his mind again and again.
I spent most of Saturday in Open Identity Foundation workshops. OIDF chair Don Thibeau enthusiastically stressed two new(ish) initiatives: Mobile Connect in conjunction with the mobile carrier trade association GSM Association @GSMA, and HIE Connect for the health sector. For the uninitiated, HIE means Health Information Exchange, namely a hub for sharing structured e-health records among hospitals, doctors, pharmacists, labs, e-health records services, allied health providers, insurers, drug & device companies, researchers and carers; for the initiated, we know there is some language somewhere in which the letters H.I.E. stand for "Not My Lifetime".
But seriously, one of the best (and pleasantly surprising) things about HIE Connect as the OIDF folks tell it, is the way its leaders unflinchingly take for granted the importance of privacy in the exchange of patient health records. Because honestly, privacy is not a given in e-health. There are champions on the new frontiers like genomics that actually say privacy may not be in the interests of the patients (or more's the point, the genomics businesses). And too many engineers in my opinion still struggle with privacy as something they can effect. So it's great -- and believe me, really not obvious -- to hear the HIE Connects folks -- including Debbie Bucci from the US Dept of Health and Human Services, and Justin Richer of Mitre and MIT -- dealing with it head-on. There is a compelling fit for the OAUTH and OIDC protocols here, with their ability to manage discrete pieces of information about users (patients) and to permission them all separately. Having said that, Don and I agree that e-health records permissioning and consent is one of the great UI/UX challenges of our time.
Justin also highlighted that the RESTful patterns emerging for fine-grained permissions management in healthcare are not confined to healthcare. Debbie added that the ability to query rare events without undoing privacy is also going to be a core defining challenge in the Internet of Things.
MyPOV: We may well see tremendous use cases for the fruits of HIE Exchange before they're adopted in healthcare!
In the afternoon, we heard from Canadian and British projects that have been working with the Open Identity Exchange (OIX) program now for a few years each.
Emma Lindley presented the work they've done in the UK Identity Assurance Program (IDAP) with social security entitlements recipients. These are not always the first types of users we think of for sophisticated IDAM functions, but in Britain, local councils see enormous efficiency dividends from speeding up the issuance of eg disabled parking permits, not to mention reducing imposters, which cost money and lead to so much resentment of the well deserved. Emma said one Attributes Exchange beta project reduced the time taken to get a 'Blue Badge' permit from 10 days to 10 minutes. She went on to describe the new "Digital Sources of Trust" initiative which promises to reconnect under-banked and under-documented sections of society with mainstream financial services. Emma told me the much-abused word "transformational" really does apply here.
MyPOV: The Digital Divide is an important issue for me, and I love to see leading edge IDAM technologies and business processes being used to do something about it -- and relatively quickly.
Then Andre Boysen of SecureKey led a discussion of the Canadian identity ecosystem, which he said has stabilised nicely around four players: Federal Government, Provincial Govt, Banks and Carriers. Lots of operations and infrastructure precedents from the payments industry have carried over.
Andre calls the smart driver license of British Columbia the convergence of "street identity and digital identity".
MyPOV: That's great news - and yet comparable jurisdictions like Australia and the USA still struggle to join governments and banks and carriers in an effective identity synthesis without creating great privacy and commercial anxieties. All three cultures are similarly allergic to identity cards, but only in Canada have they managed to supplement drivers licenses with digital identities with relatively high community acceptance. In nearly a decade, Australia has been at a standstill in its national understanding of smartcards and privacy.
For mine, the CIS Quote of the Day came from Scott Rice of the Open ID Foundation. We all know the stark problem in our industry of the under-representation of Relying Parties in the grand federated identity projects. IdPs and carriers so dominate IDAM. Scott asked us to imagine a situation where "The auto industry was driven by steel makers". Governments wouldn't put up with that for long.
Can someone give us the figures? I wonder if Identity and Access Management is already more economically ore important than cars?!
Cheers from Monterey, Day 1.
We live in an age where billionaires are self-made on the back of the most intangible of assets – the information they have amassed about us. That information used to be volunteered in forms and questionnaires and contracts but increasingly personal information is being observed and inferred.
The modern world is awash with data. It’s a new and infinitely re-usable raw material. Most of the raw data about us is an invisible by-product of our mundane digital lives, left behind by the gigabyte by ordinary people who do not perceive it let alone understand it.
Many Big Data and digital businesses proceed on the basis that all this raw data is up for grabs. There is a particular widespread assumption that data in the "public domain" is free-for-all, and if you’re clever enough to grab it, then you’re entitled to extract whatever you can from it.
In the webinar, I'll try to show how some of these assumptions are naive. The public is increasingly alarmed about Big Data and averse to unbridled data mining. Excessive data mining isn't just subjectively 'creepy'; it can be objectively unlawful in many parts of the world. Conventional data protection laws turn out to be surprisingly powerful in in the face of Big Data. Data miners ignore international privacy laws at their peril!
Today there are all sorts of initiatives trying to forge a new technology-privacy synthesis. They go by names like "Privacy Engineering" and "Privacy by Design". These are well meaning efforts but they can be a bit stilted. They typically overlook the strengths of conventional privacy law, and they can miss an opportunity to engage the engineering mind.
It’s not politically correct but I believe we must admit that privacy is full of contradictions and competing interests. We need to be more mature about privacy. Just as there is no such thing as perfect security, there can never be perfect privacy either. And is where the professional engineering mindset should be brought in, to help deal with conflicting requirements.
If we’re serious about Privacy by Design and Privacy Engineering then we need to acknowledge the tensions. That’s some of the thinking behind Constellation's new Big Privacy compact. To balance privacy and Big Data, we need to hold a conversation with users that respects the stresses and strains, and involves them in working through the new privacy deal.
The webinar will cover these highlights of the Big Privacy pact:
- Respect and Restraint
- Super transparency
- And a fair deal for Personal Information.

The latest Snowden revelations include the NSA's special programs for extracting photos and identifying from the Internet. Amongst other things the NSA uses their vast information resources to correlate location cues in photos -- buildings, streets and so on -- with satellite data, to work out where people are. They even search especially for passport photos, because these are better fodder for facial recognition algorithms. The audacity of these government surveillance activities continues to surprise us, and their secrecy is abhorrent.
Yet an ever greater scale of private sector surveillance has been going on for years in social media. With great pride, Facebook recently revealed its R&D in facial recognition. They showcased the brazenly named "DeepFace" biometric algorithm, which is claimed to be 97% accurate in recognising faces from regular images. Facebook has made a swaggering big investment in biometrics.
Data mining needs raw material, there's lots of it out there, and Facebook has been supremely clever at attracting it. It's been suggested that 20% of all photos now taken end up in Facebook. Even three years ago, Facebook held 10,000 times as many photographs as the Library of Congress:
And Facebook will spend big buying other photo lodes. Last year they tried to buy Snapchat for the spectacular sum of three billion dollars. The figure had pundits reeling. How could a start-up company with 30 people be worth so much? All the usual dot com comparisons were made; the offer seemed a flight of fancy.
But no, the offer was a rational consideration for the precious raw material that lies buried in photo data.
Snapchat generates at least 100 million new images every day. Three billion dollars was, pardon me, a snap. I figure that at a ballpark internal rate of return of 10%, a $3B investment is equivalent to $300M p.a. so even if the Snapchat volume stopped growing, Facebook would have been paying one cent for every new snap, in perpetuity.
These days, we have learned from Snowden and the NSA that communications metadata is just as valuable as the content of our emails and phone calls. So remember that it's the same with photos. Each digital photo comes from a device that embeds within the image metadata usually including the time and place of when the picture was taken. And of course each Instagram or Snapchat is a social post, sent by an account holder with a history and rich context in which the image yields intimate real time information about what they're doing, when and where.
- When you access or use our Services, we automatically collect information about you, including:
- Usage Information: When you send or receive messages via our Services, we collect information about these messages, including the time, date, sender and recipient of the Snap. We also collect information about the number of messages sent and received between you and your friends and which friends you exchange messages with most frequently.
- Log Information: We log information about your use of our websites, including your browser type and language, access times, pages viewed, your IP address and the website you visited before navigating to our websites.
- Device Information: We may collect information about the computer or device you use to access our Services, including the hardware model, operating system and version, MAC address, unique device identifier, phone number, International Mobile Equipment Identity ("IMEI") and mobile network information. In addition, the Services may access your device's native phone book and image storage applications, with your consent, to facilitate your use of certain features of the Services.
Snapchat goes on to declare it may use any of this information to "personalize and improve the Services and provide advertisements, content or features that match user profiles or interests" and it reserves the right to share any information with "vendors, consultants and other service providers who need access to such information to carry out work on our behalf".
So back to the data mining: nothing stops Snapchat -- or a new parent company -- running biometric facial recognition over the snaps as they pass through the servers, to extract additional "profile" information. And there's an extra kicker that makes Snapchats extra valuable for biometric data miners. The vast majority of Snapchats are selfies. So if you extract a biometric template from a snap, you already know who it belongs to, without anyone having to tag it. Snapchat would provide a hundred million auto-calibrations every day for facial recognition algorithms! On Facebook, the privacy aware turn off photo tagging, but with Snapchats, self identification is inherent to the experience and is unlikely to be ever be disabled.
As I've discussed before, the morbid thrill of Snowden's spying revelations has tended to overshadow his sober observations that when surveillance by the state is probably inevitable, we need to be discussing accountability.
