Abstract
With the development of software technology, the copyright of the software is increasingly important. One aspect is the copyright of the source code. This paper proposed a new algorithm named HSVN (hiding signatures in variable names) to hide the copyright signature or watermark in the source code. It belongs to the static watermark. The basic idea of HSVN algorithm is adding signature bytes into the variable names which are located by random sequence, and the difference between the alongside two chars of the specific variable name is the hidden signature byte. HSVN Algorithm can hide the signature more easily and more invisibly. Moreover, it can hide a large amount of information with little redundancy added to the program.
