A Novel Method-Based Software Watermarking Scheme

Considering three important properties of software watermarks, resilience, stealth and data rate, a new static watermarking scheme based on Chinese Remainder Theorem is proposed. The idea of secret sharing is introduced to the watermark division and retrieval, and the watermark retrieval based on the partial values has great robust. The watermark coding realized by the control-flow diagram assigning is embedded into the chosen method and has good stealth property, which offers an infinite-capacity channel for storage of watermarks with minimal increase in code size.
