Dynamic Data Flow Graph-based software watermarking
Bo Feng, Miao Zhang, Guoai Xu, Xinxin Niu, Zhengming Hu · 2009
In this paper we indicate the concept of dynamic data flow graph based on the dynamic data dependency during execution of software. On this basis, we propose a dynamic software watermarking algorithm, which embeds watermarking information into DDFG of software, and discuss the implementation of embedding and extracting watermark. Finally we analyze the performance of this algorithm.
