Abstract

Copyright infringement of intellectual properties has become an increasingly significant problem with the advent of the Internet and the utilization of Internet based information systems that allow users to disseminate files quickly and anonymously. Specifically, we are concerned with the ability to retain control of audio, video, and picture files stored within a database and commonly accessed by numerous individuals. This paper presents a novel approach to the manipulation and management of binary large objects within an active relational database management system through the application of digital watermarking algorithms and Java programming modules. We describe the design and implementation decisions and account our experience of realizing the Active Watermarking System using Oracle DBMS 10g, Oracle JDeveloper 10g, Java, and application-dependent digital watermarking algorithms, which serves as a guide for future similar endeavors.
