Image Protection by Intersecting Signatures
In this paper, we propose an exact image authentication scheme that can, in the best case, detect image tampering with the accuracy of one pixel. This method is based on constructing blocks in the image in such a manner that they intersect with one another in different directions. Such a technique is very useful to identify whether an individual image pixel has been tampered with.
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...
متن کاملImage 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 کاملAn Efficient Self-Embedding Watermarking Scheme for Colour Image Tamper Detection and Recovery
Digital watermarking is a method for inserting the watermark information into an image, which can be later extracted for variety of purposes including copyright identification and content authentication. In this study, the watermarking issue for colour image authentication is presented to resist malicious tampering. The main aim of this paper is to preserve the colour moments such that the tamp...
