A Software Watermarking Algorithm Based on Stack-State Transition Graph
XU Jin-chao, Zeng Guosun · 2010
In the Internet age, Software security and piracy becomes a more and more important issue. In order to prevent software from piracy and unauthorized modification, various techniques have been developed. Among them is software watermarking which protects software through embedding some secret information into software as an identifier of the ownership of copyright for this software. This paper gives an new algorithm based on stack-state transition graph, watermarks is embed by adding additional code in the executable file, and extracted by recognizing the relationship of stack-state which processed in runtime. Analysis proves that our algorithm is more reliable.
