Image Watermarking for Tamper Detection

We propose an oblivious watermarking technique for tamper detection in digital images. By comparing correlation values from different portions of the image, the technique enables us to distinguish malicious changes, such as replacing / adding features from nonmalicious changes resulting from common image processing operations. The technique can be implemented with small memory and computational...

Image Tamper Detection Using Non Alignment of Jpeg Grids

Digital images have a very significant role in various fields like criminal and forensic investigations, medical imaging and journalism. But due to wide availability of powerful editing software, image forgery has become much easier. The aim of this paper is to detect the forgery on JPEG compressed images when splicing (copy-paste) will result in non alignment of JPEG grids. JPEG is widely used...

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...

Nonintrusive 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...
