A Software Birthmark Based on Weighted K-gram
A software birthmark is the invariable features of a program that can used to detect software theft Software theft can be detected by a birthmark that can cover the whole behavior of a program. To improve the performance of k-grams of resisting semanticspreserving transformations, and also consider a birthmark should cover the whole behavior of a program. A static birthmark based on k-grams and their weights is proposed. Weight is computed by analyzing the rate of change of k-gram frequency between the original program and the transformed programs. Experimental results show that the performance of the proposed birthmark for Java applica tions is better than static k-gram birthmark against transfor mations performed by Smokescreen obfuscator, ZKM obfusca tor and Jarg optimizer.
