Summary of the actual paper: they take a single sensor EEG sample of your brain doing some simple task and compare it to both a set of samples of your brain doing the task (this comparison results is the selfsim value) and of a bunch of other people doing the task(resuliting in the crossSim score). "if the percent dierence between selfSim and crossSim is greater than or equal to T, we accept the authentication attempt. If not, we reject it." Of course, this actually says nothing about the feasibility of emulating someone else's signal (which may get way easier if its a single sensor). Im skeptical of this both that it will hold of to an adversarial attacker and that its actually right. Deciding that something is a unique identifier off a small sample size reminds me of some of the really bad forensic techniques people used (e.g. [0]) [0]http://www.washingtonpost.com/wp-dyn/content/article/2007/11/17/AR2007111701681.html http://www.washingtonpost.com/wp-dyn/content/article/2007/11...
