Adaptive reversible image watermarking scheme
This paper presents an adaptive block sized reversible image watermarking scheme. A reversible watermarking approach recovers the original image from awatermarked image after extracting the embedded watermarks. Without loss of generality, the proposed scheme segments an image of size 2N ×2N adapccepted 12 November 2010 vailable online 19 November 2010
متن کاملDual Watermarking Scheme with Encryption
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, will be developed to improve the robustness and protection along with security. DWT and SVD have been used as a mathematical tool to embed watermark in the image. Two watermarks are embedded in the host image. The secondar...
متن کاملA Multi-purpose Dual Watermarking Scheme
This paper proposes an image watermarking scheme that cater to multiple purposes of copyright protection and fingerprinting. For fingerprinting images, an ID number or a unique code pertaining to the buyer is hidden with in the digital resources at the time of resource transfer. For copyright protection of the resource, a unique signature such as a logo of the owner creator is integrated imperc...
متن کاملReversible Watermarking Scheme with Image-independent Embedding Capacity
Permanent distortion is one of the main drawbacks of all the irreversible watermarking schemes. Attempts to recover the original signal after the signal passing the authentication process are being made starting just a few years ago. Some common problems, such as salt-andpepper artefacts due to intensity wraparound and low embedding capacity, can now be resolved. However, we point out in this w...
متن کاملA REVERSIBLE WATERMARKING SCHEME FOR JPEG−2000 COMPRESSED IMAGES (FriPmPO1)
In this paper, we present a novel reversible watermarking scheme for image authentication for JPEG/JPEG−2000 coded images. Since the watermarking scheme is reversible, the exact original image can be recovered from the watermarked image. The watermarking scheme makes use of finite state machine principles. The proposed scheme is asymmetric as the watermark extraction key is different than its e...
