I was talking with User:Dispenser a bit on IRC this morning, he gave me permission to post his ideas to this list (since he's better at explaining these things..than I!)
dispenser: SarahStierch: I've read from Chatroulette that genital detection only has a low accuracy rate, about 20% false negatives. Face detection on the other hand is very accurate. Now somewhere on commons is guideline instituted by German privacy zealots to comply with Germany's privacy laws regarding identification of people.
[2:31pm] SarahStierch: I see [2:31pm] SarahStierch: I figured the accuracy would be low. [2:36pm] dispenser: You could lobby for a bot to start tagging faces in images for a number of reason: [2:36pm] dispenser: 1) Compliance with laws that reuses might face, e.g. in Germany
[2:36pm] dispenser: 2) Eliminating or replacing "vacation" photographs of locations that have family members in them [2:37pm] dispenser: 3) Likewise with articles of clothing, e.g. a halter top doesn't need to show a face
[2:43pm] dispenser: Something like http://commons.wikimedia.org/wiki/Template:Personality_rights
Something for us to think about while we examine policies and decide on our next steps to bringing this to the larger community. (And the pros/cons of course).
