Traitor tracing is one kind of piracy deterrent schemes that helps trace the source of leaks when sensitive or proprietary data is made available to a large set of parties. In such schemes, error correcting codes can be applied for their natural properties, known as traceability codes. In this paper, we present Reed-Solomon codes as a kind of traceability codes and use list decoding algorithm to efficiently trace the traitors. We place our emphasis upon the conditions under which list decoding algorithm can be applied successfully for Reed-Solomon codes and the maximum numbers of users and traceable traitors for particular codes.
