Watermarking Pattern Recognition in Channels with Substitution and Bursty Insertion and Deletion Errors

Abstract

A novel watermarking scheme for intrusion tracing in networks based on QIM modulation and linear error-correcting subcodes suitable for pattern recognition and combating with substitution, deletion and insertion errors in channels with invisible embedded watermarks is proposed in this paper. Statistical and computational experiments demonstrate that proposed scheme outperforms the known coded IPD-based flow watermarking schemes and has a significant advantage in detection rate and implementation complexity, but slightly inferior to the code rate, and hence to processing time for intrusion tracing.
