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...
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...

In this paper I propose an oblivious watermarking technique for tamper detection in digital images. With comparing correlation values from different portions of the image, the technique enables us to distinguish malicious changes, such as replacing / adding features from non-malicious changes resulting from common image processing operations.

متن کاملA DWT-based Digital Watermarking Scheme for Image Tamper Detection, Localization, and Restoration
The provision of image tamper detection, localization and restoration forms an important requirement for modern multimedia and communication systems. A discrete wavelet transform (DWT)-based watermarking scheme for this purpose is proposed in this communication. In our scheme, the original image is first partitioned into blocks of size 2 9 2 in which a 1D DWT is applied to produce a watermark w...
متن کاملA Semi-fragile Watermarking Scheme for Image Tamper Localization and Recovery
A novel semi-fragile watermarking scheme for Image tamper localization and recovery is proposed. The Logistic map is used to encrypt the feature extracted from the original image, then the generated watermark is embedded into the middle-frequency DCT coefficients of each block after being ordered in zigzag manner based on invariance properties of DCT coefficients before and after JPEG compressi...
