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.

Abstract

A digital fingerprint is a unique pattern embedded in a digital document to be able to identify a specific copy when it is used illegally. We have looked at two specific code structures for fingerprinting purpose. Binary linear codes, often used as error correcting codes, and what we call a binary sorted code.
