Abstract: This paper presents a robust software watermark scheme which exploits dynamic graphs to represent the watermark and employs their inner structures to tamper-proof the watermark itself, moreover it also utilizes concurrently controlled multithread to implement redundant embedding and reliable extraction of the watermark.
