Perceptual hashing and semi-fragile watermarking for the discovery, search, recognition and authentication of multimedia content

Project Details

Description

In this research project the robustness and the security of perceptual hash functions is investigated for
different media types. Research is conducted on semi-fragile watermarking techniques that - in
combination with perceptual hash functions - yield efficient selective authentication mechanisms for
multimedia content. Solutions are optimized w.r.t. complexity and accuracy, such that a practical implementation
is possible.
