The applications accessing multimedia systems and content over the Web have grown immensely in the past five years. Furthermore, many end users can easily use tools to synthesize and edit multimedia information. Thus, security has become one of the most significant problems for distributing new information technology. It is necessary to prevent illegal copying, misappropriation, and misrepresentation of digital audio, images, and video because they can be so easily copied and multiplied without information loss. It's also important to determine where and how much a multimedia file differs from its original. Thus, a need exists for developing technology that will help protect the integrity of digital content and secure the intellectual- property rights of owners.
