So Apple code is now perfect?You're comparing manufacturing defects to a scanning technology? Ok...
But heck, even if the error rate were 1/10th of what they said (1 in 100 billion), it would still be excellent.
They aren't looking for perfect hash matches. There actual error will be many times lower then claimed. Given that billions of pictures are taken. There will be a non trival number of people effected by this.
But whats a few innocent people thrown in jail if we catch just one bad guy? Right?
