Digital audio watermarking for QoS assessment of MP3 music signals
TL;DR: This work proposes an audio watermarking signal processing technique to provide a quality assessment of the received audio signal after a coding/transmission process and the results obtained through simulation trials confirm the validity of such approach.

Using intrinsically irreversible adaptive technologies to counteract the deceptions in digital watermarking
TL;DR: To effectively counteract the deceptions in multimedia ownership verification, the reversibility in the widely used and researched adaptive watermarking is investigated from a new point of view.
Digital Rights Protection - a Great Challenge
TL;DR: The paper discusses thenecessity of intellectual rights protection generally and the concepts ofDRM intoday's life, and presents the state of art concerning encryption and watermarking, themaintechnical solutions forDRM, and discusses the challenges and newdirections for this topic.

Optimized Watermarking Scheme for Copyright Protection of Medical Images
TL;DR: In this article , an effective copyright protection algorithm for medical images uses particle swarm optimization (PSO) to provide robust, hybrid, and blind watermarking, which is selected using PSO based on the medical image and watermark information.

A novel secured Euclidean space points algorithm for blind spatial image watermarking
TL;DR: In this paper , a new Euclidean space point's algorithm is proposed to authenticate the images by embedding binary logos in the digital images in the spatial domain, and the proposed watermarking methodology is tested on the standard set of raw grayscale and RGB color images.

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.
