A generalized method for constructing and proving zero-knowledge watermark proof systems
TL;DR: The paper shows that the existence of a secured equivalent operation, which enables watermark detection in a blinded domain, is one of the prerequisites of the systems' existence and verifies its zero-knowledge property.

Rotation, scaling, and translation robust image watermarking using Gabor kernels
Hiuk Jae Shim,Byeungwoo Jeon +1 more
TL;DR: A RST-robust watermarking algorithm which exploits the orientation feature of a host image by using 2D Gabor kernels to identify periodic peaks.
Proceedings ArticleDOI
Gabor transform domain watermarking
TL;DR: This work investigates the use of the Gabor (1946) transform in traditional watermarking schemes and finds that traditional detection thresholds are not applicable in this transform, thus a modified approach is employed to overcome this problem.

Digital rights protection - a great challenge of the new millennium
TL;DR: The paper discusses the necessity of intellectual rights protection generally and the concepts of DRM in today's life, and presents the state of art concerning encryption and watermarking, the main technical solutions for DRM, and the challenges and new directions for this topic.

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.

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.

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.
