A hierarchical digital watermarking method for image tamper detection and recovery

Pattern Recognition, 2005
In this paper, we present an efficient and effective digital watermarking method for image tamper detection and recovery. Our method is efficient as it only uses simple operations such as parity check and comparison between average intensities. It is effective because the detection is based on a hierarchical structure so that the accuracy of tamper ...

A secure image authentication scheme for tamper detection and recovery

Imaging Science Journal, 2012
In recent decades, many watermarking schemes for tamper detection and tampered image recovery have been proposed. However, most of these schemes suffered from several kinds of attacks due to the lack of considering security issues. In this paper, an improved and elaborately designed scheme is proposed after the drawbacks of these schemes are analysed ...

Tamper detection and image recovery for BTC-compressed images

Multimedia Tools and Applications, 2016
To ensure the integrity of images compressed using block truncation coding (BTC), a tamper detection and image recovery scheme is proposed in this paper. In this scheme, the size of the authentication data can be adaptively selected according to the user’s requirement.

Dual watermark for image tamper detection and recovery

Pattern Recognition, 2008
An effective dual watermark scheme for image tamper detection and recovery is proposed in this paper. In our algorithm, each block in the image contains watermark of other two blocks. That is to say, there are two copies of watermark for each non-overlapping block in the image.
