Modified Least Significant Bit Algorithm of Digital Watermarking for Information Security

In today’s information age, the technologies have developed so much that most of the users prefer Internet to transfer data from one end to another across the world. So privacy in digital communication is the basic requirement when confidential information is being shared between two users. The attacks on the Internet and Internet-attached systems have grown. Digital watermarking technique is used to hide the information inside a signal. In this paper, least significant bit (LSB) algorithm is discussed. The basic LSB algorithm is easy to decrypt because the watermark image is embedded into a single bit position of an original image. To remove this limitation of basic LSB algorithm, the modified version of LSB algorithm using XOR gate is used and the experimentation results are shown. Performance analysis of the algorithm is also done.
