Image Tamper Detection and Recovery based on Dilation and Chaotic Mixing
In this paper, we propose an efficient method for image tamper detection and recovery. We separate the image into several blocks, and share a block information to two other blocks. It means, there have two copies of one block information for each non-overlapping block. In implementing, we improve Lee's algorithm of watermark embedding, especially when the tampered area is a rounded region or a ...
متن کاملImage Tamper Detection and Recovery Based on Dual Watermarks Sharing Strategy
Recently, verifiable secret sharing schemes have been proposed to keep participants from providing fake or illegal stego-images. However, the schemes do not consider the recovery mechanism when parts of the information in stego-images are lost or incidentally modified during the transmission process. This paper presents a novel verifiable and reversible secret sharing scheme based on Shamir’s s...
متن کاملSubsampling-Based Image Tamper Detection and Recovery Using Quick Response Code
Quick response (QR) code is the prevalent trademark for a type of matrix barcode symbol. That code is always scanned to efficiently acquire data, especially for mobile device users. It involves the capabilities of data storage, reliable readability and strong error correction. This paper utilizes these properties of a QR code to propose an image tamper detection and recovery scheme for grayscal...
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 کاملImage 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...
