CREST: Collusion-RESistant Tracing

The CREST project (Collusion RESistant Tracing) investigates the resilience of digital watermarks against coalition attacks. A watermark is a sequence of hidden data embedded in audio/video, and is intended e.g. to trace the origin and distribution of files. A collusion attack is an attempt by multiple people, who each possess a differently marked version of the same file, to remove or distort the watermark. The cat-and-mouse game of attack and defense gives rise to some highly nontrivial mathematics, involving combinatorics, coding theory, information theory and cryptography. The practical side is equally complex, with much work in progress on attack strategies, signal processing attacks, optimal code constructions, efficient decoding algorithms, and embedding methods.

CREST is a joint project of the Eindhoven Institute for the Protection of Systems and Information (EIPSI) and industrial partners Irdeto (more here) and Civolution. The aim of the CREST project is to make progress on both the mathematical understanding and practical realization of collusion resistant watermarking.
