Abstract

The development of new multimedia services and environments requires new concepts both to support the new working process on distributed computers and to protect the multimedia data during the production and distribution. This article addresses image/video authentication and copyright protection as major security demands in digital marketplaces. First we present a content-based signature technique for image and video authenticity and integrity. Based on this technique, we introduce a tool for interactive video authentication and propose content-fragile watermarking, a concept which combines watermarking and content-based digital signatures to ensure copyright protection and detection of integrity violation.
