Digital Watermarking for Image Tamper Detection using Block-Wise Technique
Fragile watermarking has the characteristics where the inserted watermark should be easily breakable for a trivial tampering of the image. So, fragile watermarking technique is proposed for the purpose of authentication or tamper detection. In this paper, we propose an efficient image tamper detection method using block-wise technique which is able to detect the tamper locations. In the propose...
متن کاملOblivious Image Watermarking Technique for Tamper Detection
In this paper I propose an oblivious watermarking technique for tamper detection in digital images. With comparing correlation values from different portions of the image, the technique enables us to distinguish malicious changes, such as replacing / adding features from non-malicious changes resulting from common image processing operations. This technique can be implemented with small memory ...
متن کاملDigital Image Tamper Detection Techniques - A Comprehensive Study
Photographs are considered to be the most powerful and trustworthy media of expression. For a long time, those were accepted as proves of evidences in varied fields such as journalism, forensic investigations, military intelligence, scientific research and publications, crime detection and legal proceedings, investigation of insurance claims, medical imaging etc. Today, digital images have comp...
متن کاملNonintrusive Image Tamper Detection Based on Fuzzy Fusion
In this paper, we propose a novel fuzzy fusion of image residue features for detecting tampering or forgery in video sequences. We suggest use of feature selection techniques in conjunction with fuzzy fusion approach to enhance the robustness of tamper detection methods. We examine different feature selection techniques, the independent component analysis (ICA), and the canonical correlation an...
متن کاملRobust Digital Image Watermarking Technique Based on Histogram Analysis
Watermarking techniques can be classified into two main categories; Spatial and Transformational approaches. They are characterized to rely on descriptive global models through which each technique is formalized and structured using models of Steganography and Encryption. This paper presents a robust digital image watermarking technique that attributes the watermarking process to signal modulat...
