Copyright Protection

Abstract

The impact of digital consumer devices and the Internet on our day-to-day life has brought about a drastic progress in capturing, transmitting, storing and remixing of digital data. This, in turn, gives rise to challenging issues in data security to prevent its illegal use. In the area of distance education, the service providers should be able to protect the production of educational videos and the related materials from piracy. Hence the ownership rights should be preserved before these videos are deployed among students. As a mean to provide copyright protection of these data, the technique of digital watermarking may be employed. Watermarking is the process by which a digital code, i.e., the watermark1 is imperceptibly embedded in the host media2 such that the identity of the data owner (either in the form of a specified pseudo-random sequence or a given seal of the content owner) is hidden in it. The watermark characterizes a form of owner certificate applied on the host media and thus it marks the host media as being an intellectual property.
