Why? You could easily give some info to one institution, some other to another. It would just involve that the checker trusts that the info from that institution is reliable. So I give my age to some government-run repository, along with my public key. My name as well is stored there, but the government already has those facts in some database or other. Perhaps my employer stores my public key along with the "works here" fact. Still there's not more info on me in one single database than there already is; only now my public key is stored both places. Note that you can (and probably should) have several public keys, one per institution, so they can't be trivially linked.
But logging usage records, that seems like a deeper concern. Like you say, no one but the two involved know that an age-verification happened when you show your drivers license. I can't think of a good way to counter that. (Other than to randomly run queries to the databases (from random IP addresses) so that "real" or "fake" queries are impossible to tell apart. But that would put more load on the system, require users to run anonymising services, and is not very elegant at all.) Hmm. Difficult.
EDIT: I see the paper has a different technical setup, see the heading "Magic" on page 12. In the setup in the paper, the fact "over 18" (along with your picture) is to be stored in the actual SIM card (or some other physical, "tamper-resistant chip" ). I guess it would be fairly resistant to counterfeiting if the fact and picture were both digitally signed by some mutually trusted third party (the bouncer at the club just has to check the digital signature against his/her copy of the public key of that trusted authority who did the signing, and look at the picture transmitted from your phone and check it against your face. Seems to fix the logging concerns. Would love more info on that

And how would your face+voice prove that you're over 18? You'd still need a link to some trusted database, ie. a computer. If all that's needed is a face+voice, I could get at anyone's info just by posting their face+voice picture to the database, and get at _all_ the info, not just the fact that they're over 18.
A real device (doesn't _have_ to be a phone in my opinion), however, can have your encrypted private key stored on it. Only you know how to unlock the key, so unlike your face/voice/fingerprint it's not accessible to anyone but you. And when you want to prove that you're over 18, you use public key cryptography (look it up on Wikipedia, in short: keys come in public/private pairs, the public key is used for encryption, and the encrypted text can only be decrypted by the private key belonging to that pair). One simple method: your public key is stored in the database along with the fact "over 18". You say you're the owner of that exact public key, so the database uses your public key to encrypt some random text, and hands you the encrypted text. If you are able to decrypt it with your private key, you must be the person whose public key was stored with the fact "over 18".

I would not feel like I'm using a "hidden identity" or pretending to be someone else just because I prove to you that I'm over 18 without proving that my name is so-and-so. The "person who is over 18" and the "person whose name is so-and-so", etc., are still the same unique person, even if the bartender doesn't know that. And what makes the name so special? I could just as well give my place of birth, or home town, etc. etc, that's also part of me, and just as irrelevant to whether I'm old enough to buy alcohol.

Actually, AT&T, Sprint and T-Mobile did install spyware (but strangely not Verizon), a program called CarrierIQ which, among other things, recorded and uploaded keystrokes (such as "passwords to otherwise secure websites").
But I guess if your private key was only used in a Trusted Execution Environment, CarrierIQ shouldn't be able to get a hold of it, nor the output of authorisations, as long as there aren't any bugs … I guess exploits and spyware are always a risk. There would have to be heavy sanctions against any kind of CarrierIQ-like behavour with PychicID.

I liked the talk all the way up to the "shake things up" part. That just doesn't make linguistic sense. If Descartes really meant "shake things up" when he wrote "cogito ergo sum", he wouldn't have been going on about Thoughts etc. in the rest of the text. When people use words, they typically don't think about their etymological history (if they even know about it). If we did that when we spoke, we'd never get anywhere.
(Oh no! I used the morpheme "-where" which etymologically has the same proto-indo-european root as "who" so I must've meant "we'd never get anywho" which I'm sure you don't have to be too twisted to construe sexually. Whatever will I do...)

Remember the "Welsh Not" custom a hundred years ago in Great Britain, where students speaking Welsh would be given a lashing by the teacher. Similar punishment and humiliation happened to Sámi speakers in Norway, Gikuyu speakers in Kenya (where English was enforced), Ainu in Japan, and so on and so forth.

Actually…no. Machine Translation will become the universal language. Of course, it'll distort meaning and sound funny, but then so does globish.
A comment on Talk: Jay Walker on the world's English mania
He really does make this government-enforced Education sound awful.
I have to say, the fact that this talk got into TED is quite disappointing. As has been commented below, the clips are from a special school in China called Crazy English (ie. not everyone takes the screaming class) and China ranks rather low on the list of population with English as a second language.
Also, I really don't see what his argument is. Does he really believe English is somehow better-suited than other languages to be the lingua franca? (Latin had that postion at one point, French did too; not for linguistic reasons, but political ones.)
