Abstract:View of software piracy, this paper proposed an approach for measuring software similarity without sourcecode. It created dependence graphs to specify relationships between system call arguments for describing program behavior, based on which defined an dynamic software birthmark. It could be used to measure the similarity of two same-purpose applications. Experimental results indicate that the approach is effective in detecting similarity between two programs in groups of varying degrees similar, which proves its certain degree of credibility and applicability.
