It's entirely possible for biometrics to spoofed. For example, folks have already figured out how to trick deep neural nets: http://arxiv.org/abs/1412.1897 ht

It's entirely possible for biometrics to spoofed. For example, folks have already figured out how to trick deep neural nets: http://arxiv.org/abs/1412.1897 http://arxiv.org/abs/1412.1897 Not to mention bio-engineering possibilities on the horizon. Of course, just because we can use a certain technology doesn't mean we should...
