TLDR
A copyright protection method that is based on hiding an ‘invisible’ signal, known as digital watermark, in the image is presented and a variation that generates image dependent watermarks as well as a method to handle geometrical distortions are presented.About:

Secure information by using digital data embedding and spread spectrum techniques
TL;DR: In order to decode the transmitted data successfully, a novel block spread spectrum technique is also provided to increase the data survival and recovery rate from lots of different attacks.

Cyclic combination method for digital image steganography with uniform distribution of message
TL;DR: In proposed method, cyclic combination of last three bits of pixel value provide 100% chances of message insertion at the pixel value and division of image into blocks distribute the message uniformly into the image.

Research of Spatial Domain Image Digital Watermarking Payload
TL;DR: This paper makes a study of the maximum watermarking payload of spatial domain image, which is related to not only embedding intensity, but also to factors such as the size, image roughness and visual sensitivity, and so forth.

A Novel Hybrid Watermarking scheme with Image authentication based on frequency domain, 2- Level SVD using chaotic map
TL;DR: The experimental outcomes confirmed that not only the recommended scheme attained higher robustness and imperceptibility in comparison to the earlier scheme, but the Watermark image also recovered successfully with the known secret key.
Problems and Challenges in Multimedia Networking and Content Protection
TL;DR: The basic protection schemes and fundamental concepts for copyright and content originality of multimedia products through invisible watermarking are presented and the elementary partial algorithms are given and their basic characteristics are studied.

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.

The JPEG still picture compression standard
TL;DR: The Baseline method has been by far the most widely implemented JPEG method to date, and is sufficient in its own right for a large number of applications.

The JPEG still picture compression standard
TL;DR: The author provides an overview of the JPEG standard, and focuses in detail on the Baseline method, which has been by far the most widely implemented JPEG method to date, and is sufficient in its own right for a large number of applications.
