A Survey on Fragile Digital Watermarking

Dr. Dayanand.G Savakar, Shivanand Pujar

Abstract: Several major research fields have been identified in case of digital image processing and in information security, one among them is the digital watermarking. It has got the ability to make a stronger ownership of the original data and also can completely retain the original data from the watermarked data. This characteristic feature is considered to be the most essential part of some of the important media, such as medical and military images and these kinds of media do not allow any of the information part to be lost. There exist various kinds of watermarking schemes as well as techniques which are used for wide range of applications. But still there is a chance to analyse and determine the requirement of a watermarking scheme with respect to the attributes like, fidelity and capacity in the areas like content based watermarking, tamper detection, multiple watermarking etc. , by devising new schemes and algorithms. There is also a need for an effective watermarking system that has to be introduced. The requirements are application-dependent, but some of them are common to most practical applications. In this article, we discuss about need for effective watermarking process and watermark retrieval process, keeping in the mind the basic properties, Fidelity and Capacity.
