KittenAuth Test: Cute overload, man.
KittenAuth is a new system for human-checking that forgoes all the useless random string crap that people cannot read, and replaces the whole lot with pictures of cute animals.
The current 9*9 design displays 9 pictures and requires that the user clicks 3 pictures of kittens. The location of the kittens in the grid is random and to make things more fun the contents of the pictures changes too.
Regardless of the cute factor, this is essentially a combination lock. I didn’t look at the underlying code, but if you hash the sequence into a string, then compare it on the server, then do you have something secure-ish enough to keep out bots?
