Least Significant Bit Based Image Watermarking Mechanism A Review

Abstract

Now days, digital data security over network is a big issue. Digital data security and authentication is a big and challenge able research area in the field of computer science. A lot of security mechanisms are available for data authentication and privacy. For the purpose of data security and secure communication encryption mechanism are available, and also for data authentication several watermarking techniques are available. In this paper authors mainly focus research based on image watermarking approach by using least significant bit substitutions. Here authors represent comparative studies of different LSB based image watermarking approach.This paper mainly focuses on spatial domain based data hiding mechanism. The detail comparison is also given in the tabular form.
