IBC 2025
SEP 2025
12 - 15
Amsterdam, Netherlands
Fraunhofer Heinrich-Hertz-Institut (HHI) is a world leader in the development of mobile and optical communication networks and systems as well as processing and coding of video signals. Together with international partners from research and industry, Fraunhofer HHI works in the whole spectrum of digital infrastructure – from basic research to the development of prototypes and solutions.
At IBC 2025, Fraunhofer HHI presents the latest developments in Video Communication and Applications at booth B80, hall 8 on September 12-15 in Amsterdam, Netherlands.
Trustworthy authentication for compressed video data
Detecting deepfakes and restoring trust in video authenticity
Experience the next evolution in video security with the latest video coding standard H.266/Versatile Video Coding (VVC). Fraunhofer HHI has developed a method by which compressed video bitstreams can be authenticated using digital signatures – thus enabling trustworthy authentication at elementary stream level. It can therefore be applied in many important use cases that are not covered by existing technologies like C2PA. The authentication method is based on supplemental enhancement information (SEI) messages specified in H.274/VSEI and available by referencing it in H.266/VVC, H.265/HEVC and H.264/AVC.
The developed method allows also a joint digital signature of additional bitstreams associated to a video signal, such as audio or subtitles, in order to guarantee the integrity of compressed multimedia content as a whole. Furthermore, the IBC 2025 showcase comprises an integration into Spin Digital's high performance codec products.
IBC conference presentation related to our showcase
At the IBC 2025 Conference, Prof. Jonathan Pfaff will present our technical paper “Trustworthy authentication mechanism for video coding at an elementary stream level” in the session “Provenance, Authentication and Privacy”. This talk will take place on September 14, 2025, from 11:15 a.m. to 12:45 p.m.
Abstract:
Developed within the Joint Video Experts Team (JVET) of ISO/IEC and ITU-T, the presented method of trustworthy authentication enables reliable signing and verification directly in the coded video stream while remaining compatible with core codec features and real-time processing of three generations of international video coding standards. It also supports joint authentication of video and other synchronized media, such as coded audio, thereby offering practical solutions for ensuring content integrity in today’s media landscape.
