A novel digital image watermarking scheme using biorthogonal wavelets
Govindarajan Yamuna,D. Sivakumar +1 more
TL;DR: This paper has proposed a novel watermarking scheme for copyright protection in digital images performed in wavelet domain using bi-orthogonal wavelet transform and it requires original image for extracting the watermark.
Journal ArticleDOI
Experimental Study of Sparse Watermarking Techniques for Multibiometric System
TL;DR: The results show that these watermarking techniques do not have effect on authentication performance of multibiometric system, and the novelty of paper is combined compressive sensing theory with water marking technique for security of multibometric data.

Blind digital watermarking of rational Bézier and B-spline curves and surfaces with robustness against affine transformations and Möbius reparameterization
Song-Hwa Kwon,Tae-Wan Kim,Hyeong In Choi,Hwan Pyo Moon,Sung Ha Park,Heon-Ju Shin,Jung Kyo Sohn +6 more
TL;DR: A blind watermarking scheme for rational Bezier and B-spline curves and surfaces which is shape-preserving and robust against the affine transformations and Mobius reparameterization that are commonly used in geometric modeling operations in CAD systems is presented.

Journal ArticleDOI
Secure spread spectrum watermarking for multimedia
TL;DR: It is argued that insertion of a watermark under this regime makes the watermark robust to signal processing operations and common geometric transformations provided that the original image is available and that it can be successfully registered against the transformed watermarked image.
Journal ArticleDOI
Techniques for data hiding
TL;DR: This work explores both traditional and novel techniques for addressing the data-hiding process and evaluates these techniques in light of three applications: copyright protection, tamper-proofing, and augmentation data embedding.
Proceedings ArticleDOI
A digital watermark
TL;DR: The paper discusses the feasibility of coding an "undetectable" digital water mark on a standard 512/spl times/512 intensity image with an 8 bit gray scale, capable of carrying such information as authentication or authorisation codes, or a legend essential for image interpretation.
Journal ArticleDOI
Image coding based on a fractal theory of iterated contractive image transformations
TL;DR: The author proposes an independent and novel approach to image coding, based on a fractal theory of iterated transformations, that relies on the assumption that image redundancy can be efficiently exploited through self-transformability on a block-wise basis and approximates an original image by a Fractal image.
