The applications accessing multimedia systems and content over the Web have grown extremely in the past few 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 protect this information while communicated over insecure channels. It is also important to determine where and how such a multimedia file is confidential. Thus, a need exists for developing technology that will help protect the integrity of digital content and secure the intellectual property rights of owners. Cryptography is a means to achieve this task. In this paper, a secured package (library) is implemented and integrated under the hash function umbrella to provide appropriate services for protecting multimedia through communication channels. The algorithm was tested with different cryptosystems using multimedia files under windows environment and it was proved that extracting any information about the encrypted information is hard for any eavesdropper with computational resources. In addition, information security results with experimental examples are discussed and finally conclusion and remarks are presented.
