Abstract

We describe a dynamic software watermark embedded in the memory trace of an executing Java program. Our approach is a generalisation of the spread–transform watermarking technique developed for use in the multimedia domain. We show how the spread–transform paradigm enables the embedding of dither modulation watermarks in a Java program and report its robustness to realistic additive noise attacks.
