Abstract

Emerging technologies offer validation and authentication solutions in the field of audiovisual content creation. Visible or invisible watermarking, embedded metadata, and digital signatures can be used to maintain the validity and creditability of still images and video data. The Coalition for Content Provenance and Authenticity (C2PA) was established to create an open source framework and to provide technical solutions for image capture, processing, delivery, and verification. The leading market players in hardware and software development set the goal of applying encrypted metadata information to guarantee the authenticity of the data. Currently, only a few devices and applications are available and have been implemented based on this technology. This paper gives an introductory overview of the recent state, highlighting advantages, drawbacks, available implementations, and future perspectives on research directions.
