Face Recognition - Deep Detection

Artificial Intelligence face recognition is a fascinating thing.  An algorithm can detect a specific face like we can.  Probably even better?  Probably and with  an increasingly greater degree of accuracy as well as decreasing time.    

This link comments on the state of the art development.  http://www.technologyreview.com/view/535201/the-face-detection-algorithm-set-to-revolutionize-image-search/

Face is only a single data point, combined with others such as walking style or clothing, or cell phone IMSI. ID becomes relatively absolute.

Beyond the technical state of the art it would be interesting to create a metric of how frequently and to what extent degree of accuracy we are identified by biometric and location data.  The ultimate metric being real time, all the time with absolute accuracy.  For the sake of metric measurement of absolute accuracy the only metric I can unfortunately think of is the same probability of a drone kill on a person of interest?  Hardly even that current degree of accuracy in current application.  Prison execution?  At least the person to be executed is positively identified is not the cause for action.

If the all info all the time metric for personal ID was established as a 24 hour clock then how close to midnight would we be today.  On just the NSA clock how close would we be?? Bb
