A Novel Image Authentification Based on Semi-fragile Watermarking

2012 Fifth International Joint Conference on Computational Sciences and Optimization, 2012
The research and application of semi-fragile digital watermark is being paid more and more attention now, especially for content authentification. We proposes a novel design for image content authentification based on semi-fragile digital watermark using side information, which combines the modern RSA public key encryption technique with communication ...

Fragile Neural Network Watermarking with Trigger Image Set

2021
Recent studies show that deep neural networks are vulnerable to data poisoning and backdoor attacks, both of which involve malicious fine tuning of deep models. In this paper, we first propose a black-box based fragile neural network watermarking method for the detection of malicious fine tuning. The watermarking process can be divided into three steps.

Semi-fragile watermarking scheme for authentication of JPEG images

International Conference on Information Technology: Coding and Computing, 2004. Proceedings. ITCC 2004., 2004
With the increasing popularity of JPEG images, a need arises to devise effective watermarking techniques which consider JPEG compression as an acceptable manipulation. In this paper, we present a semi-fragile watermarking scheme which embeds a watermark in the quantized DCT domain.

Content-Adaptive Semi-Fragile Watermarking for Image Authentication

2007 14th IEEE International Conference on Electronics, Circuits and Systems, 2007
This paper presents a content-adaptive semi-fragile watermarking method for image authentication. The method is based on the semi-fragile watermark of Lin, Podilchuk, and Delp. However, the proposed method adapts the strength of the watermark and the detector type according to the content features of the image. Simulation results show that the proposed

A Content-Based Fragile Watermarking Scheme for Image Authentication

2004
In this paper, we present an effective image authentication scheme that can tolerate incidental distortions but that indicates tampered regions in cases of malicious manipulation. After having divided an image into blocks in the spatial domain and having obtained the average of each block’s pixel values, we represent the size relationship among three ...

A fragile invertible watermarking technique for the authentication of medical images

The 10th IEEE International Symposium on Signal Processing and Information Technology, 2010
This paper deals with a fragile watermarking technique for the authentication of medical images. Medical images are stored in archiving and communication systems that are accessed by the radiologists for diagnosis. The proposed method insure the integrity of the medical image data that is being transferred over public network.

A SVD-Based Fragile Watermarking Scheme for Image Authentication

2003
Enforcing copyright laws related to circuit design is usually hard, since discovery and proof of infringements are required beyond reasonable doubt. Proving that a given circuitry is trivially derived from a patented technique or method is in general a painstakingly slow task, often requiring reverse-engineering and forensic analysis of fabricated ...

Semi-fragile watermarking for color image authentication and recovery

The 3rd International Conference on Information Sciences and Interaction Sciences, 2010
In this paper, an efficient semi-fragile watermarking scheme for color image tamper proofing and high-quality recovery is proposed. The scheme is efficient because the validity of image blocks is simply proofed by using a dual-option parity check method and morphological operations.
