Abstract

In this chapter, hardware implementation of an LSB replacement-based digital image watermarking algorithm is introduced. The proposed scheme is developed in spatial domain. In this watermarking process, data or watermark is implanted into the cover image pixels through an adaptive last significant bit (LSB) replacement technique. The real-time execution of the watermarking logic is developed here using reversible logic. Utilization of reversible logic reduces the power dissipation by means of no information loss. The lesser power dissipation enables a faster operation as well as holds up Moore's law. The experimental results confirm that the proposed scheme offers high imperceptibility with a justified robustness.

Digital Watermarking

Watermarking is the process of inserting a mark into a multimedia object to make an assertion on the owner or the originality of the object. The use of watermark is an old age art. It began after a little time span of invention of paper manufacturing procedure. At that time, to manufacture paper, a semi liquid mixture of fiber and water is poured in a frame of mesh and distributed throughout the frame to give a proper shape and finally by applying pressure leaving off the water the fiber is cohered. In the wet fiber a picture or text can be impressed from a negative and it left a permanent mark on the paper – fibers when the fibers compressed and dried. As by water vaporization the mark is manufactured, it is called ‘watermark’, Mohanty, S.P. (1999).

In another discussion, it is noted that the watermarking mechanism was first invented about 700 years ago in Fabriano Itally, Kutter M. (1999). In this mechanism to label an article in an invincible manner a portion of the article was made slightly thin. The thinner location of the particular article could be perceived by looking at it when it is held against a strong light source. As the thinner portion looked like watery area on the article, it was called watermark.
