Robust Reversible Data Hiding Scheme Based on Gravity Center Difference
Qunting Yang,Tiegang Gao +1 more
TL;DR: Experimental results show that the original image can be recovered without any distortion after the hidden data have been extracted if the stego image has not been altered.

A Multi-Level Robust and Perceptually Transparent Blind Audio Watermarking Scheme Using Wavelets
TL;DR: The simulation results obtained show that the proposed watermarking scheme is resilient to various attacks except cropping, and the robustness of the scheme is evaluated by applying different attacks such as filtering, sampling rate alteration, compression, noise addition, amplitude scaling, and cropping.

Adaptive video fingerprinting
TL;DR: In this article, a method and system for embedding and recovering a spatial fingerprint in a sequence of video frames is presented, where a portion of the spatial fingerprint is embedded in each marked group of a first subgroup of the marked groups, and an ordering of the portion embedded in the first sub-group is used to determine whether the frame is a marked frame.

Cohort Intelligence with Cognitive Computing (CICC) and Modified-Multi Random Start Local Search (M-MRSLS) Optimization Algorithms for JPEG Image Steganography (Approach 1 and Approach 2)
TL;DR: The JPEG image format (Miano in Compressed image file formats: JPEG, PNG, GIF, XBM, BMP) is commonly used in various steganography techniques such as least significant bit insertion, masking, and filtering, transformations, etc.

Optimum detection of robust perceptual-model-based image-adaptive watermarks
Qiang Cheng,Thomas S. Huang +1 more
TL;DR: The optimum detector for the perceptual-model-based robust watermarking is constructed, and the performance analysis is investigated, finding the new detector asymptotically is most efficient for weak signals, and particularly it is the most powerful for the perceivable- model-constrained watermarks.

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.
