In the era of Information technology, Software Piracy and security has become one of the most important issue in world. Numbers of techniques have been proposed and implemented to prevent software piracy and illegal modification. Among all the protection techniques, software watermarking technique which attempts to protect the software by embedding copyright notice or unique identifiers into software to prove the ownership of software. Software Watermarking discourage piracy; as a proof of purchase or authorship; also helps in tracking the source of illegal redistribution of copies of software. We evaluate the existing dynamic watermarking algorithms using them to watermark java bytecode files and then applying distortive attacks to each watermarked program by obfuscating. Our study has shown that some watermarks were removed as results of these transformations.
