Image Tamper Detection and Recovery by Intersecting Signatures
Abstract: 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. Moreover, the
tampered region can be well recovered with the embedded recover data.
