The work presented in this paper consists in the development of a portable platform to protect the copyright and distribution rights of digital contents, and empirically demonstrate the capacity of several marking and tracing algorithms. This platform is used to verify, at a practical level, the strength properties of digital watermarking and fingerprinting marks. Initially, two watermarking algorithms, one based on spread-spectrum techniques and the other based on QIM (Quantization Index Modulation), have been implemented. Moreover, we use these watermarking algorithms to embed a fingerprinting code, based on code concatenation, equipped with an efficient tracing algorithm. In this paper we focus on the implementation issues of the Java-based platform, that consists of three main packages that are fully described.
