Abstract-- This paper presents an authentication watermarking method which can localize the tampering regions in fine granularity. Unlike the previous block-wise Tampering-Localiza...
In this work, we propose a novel fragile watermarking scheme in wavelet transform domain, which is sensitive to all kinds of manipulations and has the ability to localize the tamp...
The demand of security is getting higher in these days due to easy reproduction of digitally created multimedia data. Digital watermark is the emerging technique to embed secret i...
Authentication watermarking is the process that inserts hidden data into an object (image) in order to detect any fraudulent alteration perpetrated by a malicious hacker. In the l...
-- Digital Watermarking is used for copyright protection and authentication. In the proposed system, a Dual Watermarking Scheme based on DWT-SVD with chaos encryption algorithm, wi...
