"When can we expect it to be implemented in PM?"

We have a novel solution that is being tested by some of our longtime customers.  Unfortunately the C2PA standards are still somewhat in flux (e.g. TimeStamp manifests) and Adobe's CAI group that is implementing the C2PA SDK we use is still busy implementing some key capabilities we need for C2PA.

I will be making a formal announcement soon that describes our unique patent pending technology, and then we will open this up to further testing for those who have a camera that digitally signs with C2PA.  Currently this is only Leica's camera, but Sony has announced their solution and may likely provide the next cameras with C2PA.

It is my opinion that you need to start with a C2PA-enabled camera for this to truly work.

Sorry I have no knowledge about Nikon or any manufacturer about their rollout plans for C2PA support.

But it is my opinion that a robust C2PA implementation in a camera would include special silicon to contain the private key and accelerate the hash calculations which are very compute intensive. This would of course require a new camera and not just a firmware update.
