History of people who edited an image

[Creative B.]

Como posso saber quais pessoas editaram uma imagem?

As TAGs não foram criadas para as pessoas que editaram a imagem, mas foram editadas em PCs diferentes com números de série diferentes, ou seja, preciso obter um histórico das pessoas que editaram a imagem.

You might try the Content Credentials feature. It supports C2PA, a new industry-wide “open format for sharing information about the producer’s identity and the ingredients and tools used to make the content.”

However, it works only for images exported from a copy of Photoshop where Content Credentials is already enabled, so it will not help you for exported images you currently have. For it to work, you must require that everyone producing images for you with Photoshop enable the Content Credentials feature on all of their computers, and enable Content Credentials when exporting. Then the exported images will contain attribution information.

However, I am not sure if it will include PC serial numbers. It might contain the user’s Creative Cloud username. You may have to research it further at the Content Authenticity Initiative web site:
