Detecting Hidden Messages Using Image Power Spectrum
TL;DR: A study of the effects of data hiding on the power spectra of digital images shows that the proposed scheme is a tool for universal steganalysis with varying degrees of success depending on the type of embedding.

Dynamic prediction based watermarking for temporal relational databases
K Unnikrishnan,K V Pramod +1 more
TL;DR: This work addresses the problem of database authentication for forensic analysis of temporal databases by adding a set of bits to the original data that acts as a watermark, and shows that the proposed scheme is well suited for content protection (numerical and non-n numerical) in temporal database watermarking.

Towards Increasing the Robustness of Image Watermarking Scheme Against Histogram Equalization Attack
Vikas Saxena,J. P. Gupta +1 more
TL;DR: This paper explores an opportunity to improve the robustness of transformed domain based watermarking schemes by preprocessing the image by considering histogram equalization attack that has impact on perceptual quality.

A lossless self-recovery watermarking scheme with JPEG-LS compression
You Zhaoning,Liu Yan,Gao Tiegang +2 more
TL;DR: A fragile watermarking scheme for medical images is proposed that can judge whether the medical image is tampered or not, and can also recover the original medical images in specific conditions without any loss.

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.

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.
