A Brief Review on: Implementation of Digital Watermarking for Color Image using DWT Method
Aditya Awaghate, Rajesh D. Thakare, Sandeep Kakde · 2019
This paper describes a watermarking scheme for digital color images consisting of invisible watermarks. This scheme involves the embedding of the dual watermarks i.e, robust & fragile. By using these two watermarks for same image makes the scheme more secure. The first watermark is obtained by using DWT in YCbCr space, the second one i.e fragile watermark is used for improving least significant bits (LSB). Thus without differentiating with input image, it could be verified blindly for authentication. Therefore by using robust and fragile watermarking techniques, the original images could be protected.
