*Further Information*

*Java programs distributed through the Internet are now suffering from program theft. This is because Java programs can be easily decomposed into reusable class files and even decompiled into source code by program users. We propose a practical method that discourages program theft by embedding Java programs with a digital watermark. Embedding a program developer's copyright notation as a watermark in Java class files will ensure the legal ownership of class files. Our embedding method is indiscernible by program users, yet enables us to identify an illegal program that contains stolen class files. The result of the experiment to evaluate our method showed most of the watermarks (20 out of 23) embedded in class files survived two kinds of attacks that attempt to erase watermarks: an obfuscactor attack, and a decompile-recompile attack. ; conference paper*
