Standard Lossless Evident Watermarking—A New Approach
نویسنده
چکیده
A novel method for authentication visible watermarking with a capability of lossless image recovery is proposed. The method is based on the use of deterministic one-to-one compound mappings of image pixel values for overlaying a variety of visible watermarks of arbitrary sizes on cover images. The compound mappings are proved to be reversible, which allows for lossless recovery of original images from watermarked images. The mappings may be adjusted to yield pixel values close to those of desired visible watermarks. Different types of visible watermarks, including opaque monochrome and translucent full color ones, are embedded as applications of the proposed generic approach. A two-fold monotonically increasing compound mapping is created and proved to yield more distinctive visible watermarks in the watermarked image. Security protection measures by parameter and mapping randomizations have also been proposed to deter attackers from illicit image recoveries. Experimental results demonstrating the effectiveness of the proposed approach are also included. Index Terms — Lossless reversible visible watermarking, compound mapping, translucent water marking,

In the paper is presented a new approach for solving some of the authentication problems in large computer systems, communication networks and mobile communications, using a new method for lossless compression of some kinds of biometric information (fingerprints and signature images). The image processing is based on two-level Inverse Difference Pyramid (IDP) Decomposition with 2D Walsh-Hadamar...
متن کاملLossless authentication of MPEG-2 video
In authentication using watermarking, the original media needs to be slightly modified in order to embed a short media digest in the media itself. Lossless authentication watermark achieves the same goal with the advantage that the distortion can be erased if media authenticity is positively verified. In this paper, we extend lossless data embedding methods originally developed for the JPEG ima...
