  > That’s called DRM It's called digital signatures: > The C2PA metadata for this information can include, among other things, the publisher of the information, the device used to record the information, the location and time of the recording or editing steps that altered the information. To make sure that the C2PA metadata can not be changed unnoticed, it is secured with hashcodes and certified digital signatures. The same applies to main content of the information, such as a picture or a text. A hash code of that data is stored in the C2PA metadata section and then, as part of that metadata, secured with the digital signature. * https://en.wikipedia.org/wiki/Content_Authenticity_Initiative https://en.wikipedia.org/wiki/Content_Authenticity_Initiativ...
