The social captcha idea is neat, but sometimes my friends tag each other in pictures that aren't of them (cartoons - or places) sometimes to joke around with each other or get a friend's attention. I can see someone getting locked out of their account for being shown a picture which Facebook thinks has a given friend in it but in reality does not.
- jonknee 16y agoThat's what the skip button is for.
- stefanobernardi 16y agoThey actually have face-recognition algorithms that only show you pics where the face is clearly visible now.
- steadicat 16y agoThis is probably also a really clever use of captcha as a way to train their face-recognition algorithm.
- SammoJ 16y agoThey already have the faces annotated via the tagging system. To be really sneaky they could inject faces which have been detected but NOT tagged. However they probably have enough data anyway - enough being the largest facial recognition training data set in the world.
- elvirs 16y agoThe tagging made by users in their photos and face recognition is different. When a user has to tag someone they are given standard sized box to drag over the person you want to tag while the face recognition systems selects only the face of the person no matter how big or small it is on the picture.
- seiji 16y agoPedantic note: face recognition != face detection != face verification.
- zephyrfalcon 16y agoQuite a few people seem to have thousands of "friends" on their list, most of which they don't actually know personally; they are there because they both play some kind of game (Mafia Wars, Farmville, etc). So the social captcha idea wouldn't work in that case either...
- cemregr 16y agoI think another intention of this is making it more difficult for people to keep those fake profiles.
- tokenadult 16y agoHow exactly does social captcha slow down someone who has hacked into your friends' accounts and has seen a lot of tags on photos of friends in your friend network?
