Access Provision and Security to Digital Resources

Abstract

Usage of digital media has witnessed a tremendous growth during the last decades, as a result of their notable benefits in efficient storage, ease of manipulation and transmission. However these features make digital media vulnerable to copyright infringement, tampering and unauthorized distribution. The access provisions and security or protection of digital resources has received significant attention within the digital media community, and a number of techniques in this respect have been evolved. In this paper we have discussed some of the reasons for attacking the digital resources; authentication, authorization, data hiding techniques for copyright protection and also some relevant topics of research results.
