Wtf? They could easily hash the image on your device without transmitting the image. And of course it doesn't apply to pictures taken by someone other than you.

- gushie 9y agoAlthough hashing on the device might make it easier for someone to work out how to doctor the image so it doesn't create a match
- jdavis703 9y agoYou only need to make a one pixel change (or just use a lossy compression format) before a hash such as SHA256 or MD5 returns a false negative. You need to create a perception hash of the image. I still think that could be done on-device, but who knows what kind of machine learning/object recognition stuff they're doing on the server side.
- kiriakasis 9y agoas many have said there perceptual hashing also exist (opposed to cryptographic hashings) like phash of photoDNA
