Sony has announced in-camera forgery-proof photo technology for corporate business users that is designed to detect any modification to an image, thus protecting it from fraudulent usage.
It is currently only available for the Sony a7 IV although other cameras models are expected to follow.
When the in-camera signing mode is activated, images are immediately cryptographically signed by the camera processor upon capture. Any pixel modification, tampering or potential forgery will cancel the image signature, as the image manipulation will be detected by the customer’s own certificate server during examination.
Currently available for business users with plans for further model expansion to follow.
Further details can be found on Sony’s website.
