Copyright Protection ofWeb Applications through Watermarking

Java has become a very popular programming language, especially for designing Web applications. Java bytecode technique makes it with high portability. However, it also poses large dangers to malicious users. Many techniques have been proposed for software copyright protection. They are useful for stand-alone Java applications. Due to special characteristics of Java Web applications, copyright protection faces new challenge. In this paper, we propose a copyright protection scheme for Java Web applications. The core of this scheme is a software watermarking algorithm. Code tamper-proofing and code obfuscation are also applied to watermarked Java code for better protection. The experimental results demonstrate the feasibility of the scheme
