So, as you probably know, Ice Cream Sandwich has face unlock (which can be defeated with a photograph on another phone.)
Can anyone tell me if the recognition algorithm specifically tuned to recognise faces only?
I expect so - most face recognition algorithms work by comparing distances between features on the face. However, I'd like someone to try something out...
You have seen Inception, right? (a missed opportunity - where was the Freud? Where was the Dali?)
Anyway, I did like the idea of the totem - a physical object, something unique, which only the owner would be familiar with. The idea is that nobody else could replicate the object exactly and so the owner can detect if he or she was in an artificial reality.
So, I thought, rather than use your face (which is usually in the public domain and frequently in photos and videos) as a key, would it be possible to use an object to lock and unlock the phone - like the totem in the film?
And of course you can change your totem more easily than changing your face.
Just one problem... what if you lose the totem?
ok then, how about... Dental Record Unlock?
