Abstract: Abstract In a fingerprinting scheme, marks are embedded in a digital object to protect intellectual property. Dishonest users can collude, change some of the marks and create a new copy. In this case codes with the 'identifiable parent property' or IPP codes [4], provide means of traceability. Here, both a new decoding algorithm for IPP codes and an improvement of earlier algorithms are presented.
