Mindlocks on the horizon

Wasn’t expecting this development quite so soon after my mention of mindlocks in the context of Digital Telepathy. But is precisely the sort of thing I was talking about.

I first proposed brain based authentication in an email to Dr Larry Farwell about 10 years ago when I came across an article describing his own work as the discoverer of “Brain Fingerprinting” My specific proposal was based on the conjecture that, for example, my own brain wave reaction to, say, a photograph of my own late Father, would be dramatically and reliably different to anyone else’s reaction to the same photograph and that, if measured, that reaction could be used as a form of biometric identifier for the purposes of authentication.

But actually my main hope for brain based authentication is that it offers the only conceivable solution for the “final” authentication problem; viz the one thing we can’t yet test for – is the individual whose identity we have just verified operating under duress? This is a vital authentication test in certain critical situations. For example, it would very useful to build it into the protocols which control the launch of intercontinental ballistic missiles! I’m perfectly sure that existing procedures can reasonable verify the identity of the operators arming the missiles, but can it tell whether the operator is only performing their task because they have a gun pointed at their head? Of course it can’t. But it would be very reassuring to the rest of us if we knew the system COULD make that assessment and block the launch if the operator was found be performing under duress.

But it would also be just as useful, though not quite so dramatic, if we could ALL protect our important actions the same way. If and when I ever have a million quid in the bank, for example, I would quite like to know that I couldn’t transfer the dosh to another person’s bank account without the authentication system verifying that I wasn’t conducting the transfer under duress.

And, of course, in a Trusted Surveillance system, the same tests would trap all sorts of evil, from corrupt border guards to forced sexual consent.

The mindlocks which I casually mentioned in the Digital Telepathy story are based on a related notion, not, this time, of duress but of “intentionality”. The idea being that if – as in the story – we’re all capable of digitally recording everything we’re in range of, then the first level of abuse will be the illicit publication of such recordings without the consent of the other parties present. I propose privacy locks to solve that problem. They involve the recordings being locked with shared keys and a cryptographic protocol to ensure that all parties present have agreed and implemented the locks. But that would also prevent “private” playback within even your own head which is a) too restrictive and b) blocks potentially extremely useful functionality (aides memoire, personal diaries, recording minutes, private pleasure etc).

Mindlocks based on intentionality could solve that problem. They would permit private viewing of the recordings (only within your own head) and instantly lock the recording if they detected any intention on your part to share the recordings without the required consent of the other parties.

This research brings all the above a small step closer.
