In recent days the computer communication and the usage of multimedia data is enormous in the Internet, so protection of those data from malicious attacks and signal processing operations are very important. In specific, geometric attacks are considered as serious attacks which make watermarked work get distorted such that it is difficult to extract hidden information. In this paper the detailed study is made on the various geometric attacks invariant watermarking algorithms and also a comparative study report is present for geometric attacks invariant watermarking systems.
