Abstract

A white box traitor tracing scheme may execute, in the general decoder setting, providing consistency and/or privacy. The schemes may be instantiated under various assumptions ranging from public key encryption and non-interactive zero knowledge (NIZK) proofs, to indistinguishability obfuscation, with different trade-offs.
