Since digital documents and objects can be duplicated and distributed easily and economically cheaply and software is also a type of digital objects, software security and piracy becomes a more and more important issue. In order to prevent software from piracy and unauthorized modification, various techniques have been developed. Among them is software watermarking which protects software through embedding some secret information into software as an identifier of the ownership of copyright for this software.
