- hatu 12y agoNot just any audio but known audio. Finding known video is something they can do already too. That's why some people upload clips from their favorite shows and flip them horizontally to avoid automatic detection. Think of it like a hash for the audio/video portion. Pretty easy to check if it's in the database.
- tedunangst 12y agoI'm surprised whatever feature detection they use isn't robust against trivial changes like that. Rotation, flipping, and scaling/cropping should all result in the same hash.
- viewer5 12y agoWe only brushed over how hashes work in college, so I may be totally ignorant, but-- wouldn't rearranging the order of the data (rotate, flip, etc) necessarily change the resulting hash?
- icebraining 12y agoThey don't use those hashes, they use content fingerprinting: http://en.m.wikipedia.org/wiki/Digital_video_fingerprinting http://en.m.wikipedia.org/wiki/Digital_video_fingerprinting
