Las Vegas, USA
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 NAB Show 2025, Fraunhofer HHI presents the latest developments in Video Communication and Applications at booth W2857, West Hall on April 5-9 in Las Vegas, USA.
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 that has been adopted as part of VVC and by which compressed video bitstreams can be authenticated using digital signatures – thus enabling trustworthy authentication at elementary stream level.
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 authentication method will be soon available as part of amendments of the widespread video coding standards H.264/AVC and H.265/HEVC.
