ID Cards plan (2)
Now that I've had a chance to see the National ID Card Delivery Plan 2008, as announced today by the Home Secretary, here are some initial reactions.
What's better:
- There's a recognition that in the vast majority of cases, an ID Card would offer no sigificant benefit to the citizen over what a passport can already provide;
- The long-awaited Crosby Report on the potential for public/private sector reliance on the National Identity Scheme has at last been published;
- The Plan notes Crosby's recommendations and says they will be considered;
- The Plan announces a consultation period running up to the end of June 2008, and sets out topics on which views are sought.
What's still not so good:
- The report could do more to clear up the confused picture the public has been given to date, of the National Identity Scheme as a whole, the National Identity Register and its components, the different credentials involved, and the relationship between the NIS 'delivery partners' and the expected 'consumers' of NIS services;
- The number one recommendation of the Crosby Report is that the Scheme should be operated for one purpose: that of enabling citizens to assert their identity "with ease and confidence"; any use of the Scheme to provide 'joined-up government services' should be a matter of citizen choice and opt-in. That re-balancing of the purpose of the Scheme is still not well reflected in the Plan, which is a great shame. Among other things, it would do much to clarify the Scheme's scope in terms of the Data Protection Act;
- The choice of students as the first target population for a voluntary card reflects a continuing weakness of the proposal: the incentive of convenience which is cited as the likely motivator for take-up is not convincing, and is based on assumptions about commercial-sector service provision (of loans, mortgages and bank accounts) which are largely unproven.
The Plan reflects a complex scheme with many actors, including:
- the Identity and Passport Service
- the Department for Work and Pensions
- the Border and Immigration Agency
- UKVisas
- the Foreign and Commonwealth Office
- the (proposed) NIS Commissioner
- The citizen
- The 'consumers' of NIS services:
- Law enforcement agencies
- Intelligence services
- Government departments and local authorities
- Financial services institutions
- Other commercial sector service providers
And any or all of these may be non-UK entities.
The resulting web of departmental charters, policies and processes, public- and private-sector organisations, the divergence between citizens' and law enforcement interests, and the applicable legal and regulatory regimes can not be reduced to a simple, compelling implementation plan, however seductive that idea may appear to the policymaker. Nor do I think, in terms of governance, that it is sufficient to point to the Data Protection Act 1998 and assume that it provides the safeguards required to ensure that the Identity Cards Bill is put correctly into operation.
As the decade since the DPA's introduction has unfolded, our understanding of digital identity has evolved and - I would hope - matured.
We can now see, for instance, how much a successful identity register would have to rely on the abilitty to make highly-selective disclosures of identity attributes; we can appreciate the importance of finding ways to make some kinds of data 'evaporate' after use; of finding far more sophisticated ways of using meta-data to control the way in which personally identifiable information is stored, exchanged and processed; of finding better ways to protect data privacy 'beyond first disclosure', in a highly distributed and globally networked environment.
The DPA has nothing to say on any of those topics.
Of course, the announcement of a period of public consultation is welcome, and I sincerely hope it reflects a desire to listen carefully and change the Scheme where it needs to be changed. That said, it's now five years (and 3 Home Secretaries) since David Blunkett announced the plans for a national ID Card, and two years since the enabling legislation was enacted. How did we get this far down the line without it?
Government's ID Cards re-think still not clear
Unsurprisingly, Home Secretary Jacqui Smith bagged the 08:10 'main political interview' slot this morning on Radio 4, for a trailer of her statement on ID Cards later today - though it must have been an editorial toss-up between that, and covering yesterday's rejection of calls for a referendum on the EU Constitution Lisbon Treaty.
Ms Smith acknowledged a couple of the major changes in the Government's thinking on ID Cards, but was less clear about some of the ways in which it has remained the same. For instance she referred to the decision, sneaked out in the 'dead season' just before Christmas 2006, to base the National Identity Register (NIR) on a federation of three existing departmental databases, rather than on a single monolithic repository.
She also hinted at some of the difficulties the Government has faced - particularly under Tony Blair - over its inability to come up with a consistent and compelling justification for the NIR... is it to protect against benefit fraud and illegal working (remember the Entitlements Card?), is it a counter-terrorism and immigration measure, or is it the cornerstone of joined-up e-government... all for the comfort and convenience of you, the decent, hard-working taxpayer and law-abiding citizen?
She outlined plans for compulsory ID Cards to go first to foreign nationals from outside the EU, then to those UK citizens who work in sensitive places such as the 'airside' areas of airports, and then to be offered to students on a voluntary basis. This at least suggests a willingness to adopt a more 'segmented' approach to ID Card deployment, based on a more flexible range of perceived and potential benefits (some relating to public safety, and some to personal convenience).
She used the terms 'ID Cards', National Identity Scheme and 'NIR' more or less interchangeably in the course of the interview - which I find extremely unhelpful. It serves no-one else's interests to continue to blur the picture of how the National Identity Scheme, the National Identity Register, the Identity Card itself and the biometric passport are inter-related.
But the lack of clarity really sufraced under questioning from James Naughtie about whether the NIR would simply be a honeypot for hackers, or a massive data breach waiting to happen. She reverted to a defence of "this database" (as opposed to "these databases"), making it unclear which repository she was referring to, and assured Mr Naughtie that the scheme would not require 'large amounts of data to be kept on one database'; she described the required data as a 'relatively thin amount of information', 'roughly the same as the amount kept on the passport database'.
With respect, this simply fudges the issue. I take the point that federating multiple databases potentially reduces the amount of personal data which needs to be held in each about any given individual, but first, a 'small' amount of data about each of 70 million people (and rising) is still a large amount of data.
Second, the enabling legislation for the NIR, introduced back in 2005, defines a substantial swathe of information which may be recorded in the Register - there's a list here of what is included. It's quite obvious that it includes more than is currently stored in the UK passport database (for instance, it can include the index numbers of any other credential issued to the individual). Then there's all the metadata regarding the audit trail of requests for access, changes to the data, a separate identifier/password pair which the citizen will use when making an access request, details of "a method of generating such a password or code", and a set of questions and answers to be used as an alternative means of verifying the individual. Presumably those will be of the nature of 'password recovery' questions - that is, something sufficiently personal for the applicant to be able to remember indefinitely. I don't have any such information in place relating to my record/s in the passport database. Dave Walker has written very persuasively about the notion that the greatest threat to the security of large-scale databases arises out of poor management of precisely this kind of meta-data.
The NIR will include the citizen's principal address, and the address of any other place where they have a place of residence, whether inside the UK or not. By contrast, the Passport service said in 2005 that "we do not ask passport
applicants to keep their address given at the time of the application up
to date throughout the 10 year life of the passport."
Then we got to the interesting bit. Ms Smith said that access to the database of biometric data would be available only to a very small number of highly security-cleared individuals, and that the database would not be susceptible to hacking because 'it will not be online'.
That implies some very basic principles of system design and functionality. For instance, it means that all validation of biometrics will be done by matching the holder's biometric against the card itself, not against the centralised database. I believe there is already a European country in which that approach has been taken to its logical conclusion: the citizen's biometrics are stored only on their card, and no cental record is kept. It also creates a small community of people who could become the targets of coercive attacks, or could themselves instigate an insider attack for wathever reason. I agree that it's probably better that that community should be a small one than a large one, but I entirely disagree that taking a database offline guarantees that it can't be hacked.
I also wonder whether it will indeed be 'offline'; that again implies some quite fundamental design and implementation principles: the architecture of a federated database system is materially affected if one of the databases you expect to federate is not networked with the others.
Maybe Ms Smith didn't really mean 'offline', but meant that the biometrics database would only be network connected to the other NIR repositories, and would not itself be directly connected to other networks. The other repositories, though, presumably do have network connections, and therefore represent potential routes into the biometrics database from the outside world. Saying that a database 'is not online' is not the same as saying that it 'is connected to the network but only via other databases which are online'.
As long as even comparatively benign questioning such as Mr Naughtie's is sufficient to reveal, within a few minutes, these kinds of lack of clarity, I will continue to worry about the prospects for a national identity system being implemented in a way which does not simply increase the risk to the citizen.
