Anonymous Fingerprinting Based on Committed Oblivious Transfer
Abstract. Thwarting unlawful redistribution of information sold electronically is a major problem of information-based electronic commerce. Anonymous fingerprinting has appeared as a technique for copyright protection which is compatible with buyer anonymity in electronic transactions. However, the complexity of known algorithms for anonymous fingerprinting deters their practical implementation, since they rely either on secure multiparty computation or on general zero-knowledge proofs. A scheme for anonymous fingerprinting based on committed oblivious transfer is presented in this paper where all computations can be performed efficiently.
