Tree-Ring Watermarks: Fingerprints for Diffusion Images that are Invisible and Robust
TL;DR: Wen et al. as mentioned in this paper proposed a tree-ring watermarking technique that embeds a pattern into the initial noise vector used for sampling, which is then checked for the embedded signal by inverting the diffusion process to retrieve the noise vector.

Data hiding in MPEG-2 bitstream by creating exceptions in code space
TL;DR: A file-size preserving algorithm to hide data directly in MPEG-2 bitstreams without violating the syntax is developed, based on the realization that embedding of a bit directly in the bitstream can be achieved by creating an exception in the code space.

A Secure Blind Watermarking Scheme Based on Embedding Function Matrix
Wang Xiao,Liu Shuo +1 more
TL;DR: Experimental results show that the proposed scheme is robust to geometrical attacks and common image processing attacks, and can enhance the security of watermark.

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.

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.
