Traitor Tracing in Content Distribution: State of the Art

Citation: Peter Meerwald-Stadler, Traitor Tracing in Content Distribution: State of the Art, in: Jusletter IT IRIS

Traitor tracing algorithms employed by the content provider allow to trace back content piracy to the source, thus discouraging redistribution of decryption keys and decrypted content. Due to recent advances, e.g. Tardos codes, and research results on cryptographic primitives, e.g. indistinguishability obfuscation, technological barriers are reduced and we might see more of these systems employed. We simply review the state-of-the-art in traitor tracing algorithms, and highlight their capabilities and limitations in plain language.
