Asymmetric Fragile Watermarking Using a Number Theoretic Transform
نویسندگان
چکیده
We propose an asymmetric fragile watermarking technique that uses a number theoretic transform (NTT). Signature data is extracted from a watermarked image by determining correlation functions that are computed using the NTT. The effectiveness of the proposed method is evaluated by simulated detection of altering. key words: number theoretic transform, asymmetric watermarking, fragile watermarking, image authentication

Fragile watermarking using finite field trigonometrical transforms
Fragile digital watermarking has been applied for authentication and alteration detection in images. Utilizing the cosine and Hartley transforms over finite fields, a new transform domain fragile watermarking scheme is introduced. A watermark is embedded into a host image via a blockwise application of two-dimensional finite field cosine or Hartley transforms. Additionally, the considered finit...
متن کاملReversible Semi-fragile Image Authentication Using Zernike Moments and Integer Wavelet Transform
Semi-fragile image authentication based on watermarking has drawn extensive attention. However, conventional watermarking techniques introduce irreversible distortions to the host signals and thus may not be allowable in some applications such as medical and military imaging. Though some reversible fragile authentication algorithms had been developed, reversible semi-fragile authentication pres...

At the same time, secure image archiving is becoming a major research area because the serious concern is raised about copyright protection and authority identification in digital media. ...
متن کاملSeparable Watermarking Technique Using the Biological Color Model
Problem statement: The issue of having robust and fragile watermarking is still main focus for various researchers worldwide. Performance of a watermarking technique depends on how complex as well as how feasible to implement. These issues are tested using various kinds of attacks including geometry and transformation. Watermarking techniques in color images are more challenging than gray image...
متن کاملFragile Watermarking using Chaotic Sequences
In this article we propose a new fragile watermarking algorithm that provides the means to verify the integrity of JPEG images. We begin by presenting the cryptanalysis of CWSA (Chaotic Watermarking Scheme for the Authentication of JPEG Images), an existing fragile watermarking algorithm. We analyse its weaknesses and we propose a new version that is resistant to those attacks, faster and less ...
