A Dynamic Graph Software Watermarking Scheme Based on Variable Tamper-Proofing
Meng Liu · Computer Engineering and Science · 2011
In order to improve the robustness of software watermarking and the quantity of hidden information,a dynamic graph software watermarking scheme based on variable tamper-proofing is put forward.The big watermark is split into a set of small watermarks and they are represented as a set of graphs,which are embedded into the program dynamically.The paper encodes the watermark with a parent pointer of the dynamic graph node,and combines graph nodes and the original grogram variables for tamper-proofing.The results of experiment show that the watermark is not obviously effective in changing the program speed and results,and can resist many types of attacks.
