2020 arXiv   pre-print
We propose AMP, a system that ensures the authentication of media via certifying provenance. AMP creates one or more publisher-signed manifests for a media instance uploaded by a content provider.  ...  The authenticity of the media can be communicated to the user via visual elements in the browser, indicating that an AMP manifest has been successfully located and verified.  ...  We present a practical system named AMP (for authentication of media via provenance) aimed at providing robust verification of provenance while supporting a wide variety of production and distribution  ...

Vronicle: A System for Producing Videos with Verifiable Provenance [article]

Yuxin Liu, Yoshimichi Nakatsuka, Ardalan Amiri Sani, Sharad Agarwal, Gene Tsudik
2021 arXiv   pre-print
It allows a video consumer to authenticate the camera that originated the video and the exact sequence of video filters that were subsequently applied to it.  ...  One contribution of Vronicle is the design of provenance information that allows the consumer to verify various aspects of the video, thereby defeating numerous fake-video creation methods.  ...  AMP uses watermarking methods to embed provenance information to the media and therefore does not allow editing of the videos, as it breaks the watermarked information.  ...
