      I’m not quite sure what you’re getting at. The basic idea is to be able to easily trace back wether or not a photo has been edited, as well as provide some level of proof the photo is authentic. However this is just a lock waiting to get picked to me. Hence my cat and mouse analogy.

        Your initial comment said you feel like it’s a band aid or spam. It’s cryptography. It’s not a lock waiting to be picked. It’s a fantastic start.

          It literally is a lock waiting to get picked. The keys have to be somewhere on the device to create the signature of the photo. This can be reverse engineered, although it may not be trivial.

            Seriously, if cryptography can be reverse engineered we have a big fucking problem and photography will be the least of our issues.

              It’s clear you don’t have a great understanding of how this works. You don’t have to break cryptography. You simply need to extract the cryptographic keys from the device and then reverse the algorithm it uses to create the sig of the photos.

              So you’re saying there’s never been an instance of private keys getting leaked or extracted ever? And there’s probably easier ways to break this than trying to extract the keys, especially if they’re in some kind of secure chip. People can get the hardware, they can do whatever they want to it. Of course it’s most likely going to be a lot harder than copying someone’s SSH keys off a hard drive.
