In the CDMA-based fingerprinting scheme, a fingerprint sequence is composed of two kinds of spread spectrum sequences generated from DCT basic vectors and PN sequences. In this study, the DCT basic vectors are randomly permuted in order to reduce the interference among colluders' fingerprint sequences, which effect is similar to the interleaver used in Turbo codes. Our experimental results reveal that the false-positive probability is reduced without degrading the traceability. © 2010 IEEE.
