How on top of security do you think all the camera manufacturers are going to be? That is, how long until people can sign videos that were not, in fact, shot with their camera?
replyProving that you were able to upload something that is not real would go viral so it's very attractive to people to share such findings, meaning it would not last long, then they fix it and that's it, specially because they can require you to upgrade your camera's firmware if you want to keep using their attestation service.
replyDepends on what kind of compromise occurs. Hardware level key loss isn't easy, if possible at all to fix.
replyOnly if you're paying them
replyAttention is valuable these days, so making people go to their websites for people to check if something is real is good for them, its people they can try to sell more cameras (or phones) and all that.
replyThey can attest pictures of my hairy pendulous ballsack.
replyJoking and all but sexting would benefit from this technology, if it can vouch about the time, GPS location and email address of the owner then the receiver can have some certainty about the pic (if the sender decides to share such attestation link/info, of course)
