Abstract

Traceability codes are designed to be used in schemes that protect copyrighted digital data against piracy. The main aim of this paper is to give an answer to a Staddon–Stinson–Wei’s problem of the existence of traceability codes with qw2 and bq. We provide a large class of these codes constructed by using a new general construction method for q-ary codes.
