Hopefully we'll get some rise in use of image provenance:
> The Coalition for Content Provenance and Authenticity (C2PA) addresses the prevalence of misleading information online through the development of technical standards for certifying the source and history (or provenance) of media content. C2PA is a Joint Development Foundation project, formed through an alliance between Adobe, Arm, Intel, Microsoft and Truepic.

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...
