Digital Image Watermarking Using Discrete Fractional Fourier Transform for gray scale Image

Abstract

This paper surveys in recent advances in watermarking techniques in digital images. Digital watermarking is to
include subliminal information about multimedia information to provide a security service or simply a labeling application.
It’s possible to recover the embedded message, if the information is some non-destructive attacks, it’s malicious or not. It’s
commercial application range from copyright protection to digital right management. . In my major work describe a
watermark embedding technique for images using discrete fractional Fourier transform. In this method it's totally based on
power and Location. After embedding and extracting when we get watermarked image than my work is if any noise attack
will apply on that image than that message will distory at that t-time.
