ABSTRACT Digital image manipulation software is now readily available on personal computers. It is therefore very simple to tamper with any image and make it available to others. Ensuring digital image security has therefore become a major issue. Watermarking has become a popular technique for copyright enforcement and image authentication. The aim of this paper is to present an overview of some possible attacks which may cause harm the present watermarking techniques. Here we have identified…

This paper presents a counterfeiting attack and demonstrates that the semi-fragile watermarking method is not even fragile against complete counterfeiting, making it incapable of detecting image tampering.
Digital watermarking for image using FELICS algorithm in VLSI implementation
A new watermarking and Fast Efficient Lossless JPEG Image Compression scheme is proposed to optimize security, copyright, authentication and compression rate when watermarks are embedded into JPEG 2000 compressed images.
Digital image authentication based on second-order statistics
A combination of MSS and a feature extraction technique called second-order feature statistic to build an authentication scheme which produces a high quality image and protects the image integrity.
Hardware Implementation of a Digital Watermarking System for Video Authentication
Experimental results show that a hardware-based video authentication system using this watermarking technique features minimum video quality degradation and can withstand certain potential attacks, i.e., cover-up attacks, cropping, and segment removal on video sequences.

A Survey of Watermarking Algorithms for Image Authentication
The notion of image content authentication and the features required to design an effective authentication scheme are introduced, and some algorithms are presented, and frequently used key techniques are introduced.
Blind detection of malicious alterations on still images using robust watermarks
An original method to protect image authenticity using an invisible and robust watermark that is independent of the signer, however the latter must have a high capacity and be able to extract the watermark in full blind detection mode.

We propose a new method for invisibly watermarking high-quality color and gray-scale images. This method is intended for use in image verification applications, where one is interested in knowing
A Watermark for Image Integrity and Ownership Verification
The invisible authentication watermark inherits the security of a cryptographic hash fun tion, hence it is computationally infeasible for any user to confuse the image integrity or owners by forgery.
A digital watermark
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. The watermark is capable of carrying such
A watermark for digital images
This work describes two techniques for the invisible marking of images and analyzes the robustness of the watermarks with respect to linear and nonlinear filtering, and JPEG compression.
