Abstract: A method, device and system of a watermarking server authenticates a user in a watermarking application of a mobile device as the user of a trusted third-party communication platform. The method determines whether a photograph is captured using a front camera or a back camera of the mobile device. The method assigns a unique identifier to the photograph so that the photograph is referenceable using the unique identifier, in case of post-modification by at least one of the user and other users of the trusted third-party communication platform. The method generates a watermark applicable to the photograph, and generates a trusted image based on the photograph by appending the watermark and the unique identifier to the photograph using a processor and a memory of the watermarking server. The method automatically posts the trusted image to the trusted third-party communication platform.
