A code and domain independent traitor tracing system based on the eigen-decomposition of fingerprinted images

Conventional traitor tracing approaches focus on creating associations between multimedia fingerprints through anti-collusion codes. In this paper, we explore the possibility of creating a code and embedding domain independent fingerprint detection strategy by performing an eigen-decomposition of the fingerprinted images. The resultant Basis which spans the space of valid fingerprinted images and their respective projections are used as side-information for traitor tracing. Any colluded image is projected onto this eigen-space and the nearest neighbours are identified as potential traitors. The proposed architecture was found to be sensitive to linear and non-linear collusion operations permitting traceability, but remained robust to filtering, JPEG compression and noise addition.
