%X By combining interval-based watermarking flow modulation approach with spread spectrum communication principle, this paper proposed an interval-based spread spectrum watermarking (IBSSW) scheme for efficiently and simultaneously tracing multiple network traffic, which utilized multiple orthogonal pseudo-noise codes to spread different watermark bits and embeded them into randomly selected intervals by modulating the statistical characteristic of packets arriving time. Statistical analysis and empirical results indicate that IBSSW scheme, robust against multi-flow and mean-square autocorrelation attacks, can effectively trace multiple network flows.
