In this paper, a simple and efficient watermarking method for soft IP protection is proposed, in which a special watermark module for copyright detection is added to the original hardware description language (HDL) codes to replace a set of selected stable register data. The watermark can survive after synthesis, placement and routing to protect the soft IP core at various design levels. The reliability and robustness analysis indicate the proposed method can resist both the removal attacks and forging attacks. Also the experiment results demonstrate that our method is easier to implement at a low hardware overhead compared with the other methods, and the embedded watermark can be detected easily for copyright authentication. Moreover, it could be conveniently integrated in real soft IP cores.

Abstract. Software watermarking is the process of hiding information in a program or source code to protect the piracy of the software. Software piracy is a great threat for software industry because of every country losing millions of dollars every year. To protect the software piracy of the software's, variety of prevention techniques have been developed for copyright protection of software codes using both hardware and software. But, unfortunately no single technique is currently strong enough to protect the piracy of software codes. However, through a combination of techniques software developers are using for better protection of their software codes. In this paper, we have explained various static and dynamic techniques of software watermarking. In static watermarking techniques, the watermarks are stored in the source code, either in data section or code section where as in dynamic watermarking techniques the watermarks are generated during program execution. In this paper we have proposed a combination of static software watermarking techniques for structural programming by equation reordering and function dependency oriented sequencing (FDOS). In this method we embed the watermark in source code by a nested procedure wherein we firstly interchange the safe operands of mathematical equation and secondly impose an ordering on the mutual independent functions by introducing bogus dependency.
