billion-scale face recognition

Face recognition is consistently making huge buzz in the media. Indeed, there exist many good algorithms, that work at smaller-scale (recognizing within a small group of people). Nevertheless, face recognition at the planet scale (billion-scale) or even million scale is a hard open problem.

In this post, I’d like to share with you why it’s a hard problem, how can we solve it, and why solve it (isn’t it a threat to humanity???). Feel free to comment.
