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...

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. This technique can be implemented with small memory ...
متن کاملDigital Watermarking Methods for Authentication, Tamper Localization and Lossless Recovery
This thesis addresses authentication watermarking and compression of digital images under zero-distortion and maximum-per-sample-distortion constraints. In this context, a hierarchical authentication watermark is proposed for securely verifying the source and integrity of digital images and for determining altered image regions when the integrity verification fails. The proposed approach elimin...
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...
متن کاملReversible Medical Image Watermarking For Tamper Detection And Recovery With Run Length Encoding Compression
Digital watermarking in medical images can ensure the authenticity and integrity of the image. This design paper reviews some existing watermarking schemes and proposes a reversible tamper detection and recovery watermarking scheme. Watermark data from ROI (Region Of Interest) are stored in RONI (Region Of Non Interest). The embedded watermark allows tampering detection and tampered image recov...
