Abstract

Traceability codes are identifiable parent property (IPP) codes with the additional requirement that the Hamming distance can be used to trace a parent of a word. Traceability codes can be used for constructing digital fingerprints in order to deter users from illegally copying digital data. We construct a class of traceability codes and determine the exact parameters of some of the codes in this class
