A recent blog post mentioned that the Android and Apple phone specifications call for at least a 1 in 50,000 probability of a false match. In other words, a randomly selected imposter will have a 1 in 50,000 chance of unlocking your phone with his fingerprint. Let’s visualize that.
When people, companies, or organizations make a choice about a particular identity mechanism, they are making an economic decision. Every mechanism has a cost – and these costs should be balanced.
