Reversible medical image watermarking for tamper detection and recovery
2010 3rd International Conference on Computer Science and Information Technology, 2010This research paper discussed the usage of watermarking in medical images to ensure the authenticity and integrity of the image and reviewed some watermarking schemes that had been developed. A design of a reversible tamper detection and recovery watermarking scheme was then proposed.

Tamper detection and self-recovery scheme by DWT watermarking
Nonlinear Dynamics, 2014We present a tamper detection algorithm based on cat map and discrete wavelet decomposition. The algorithm is fragile to any tampering modification, but it is robust to harmless common image processing operations like JPEG compression, resizing, noising and filtering.

A Fragile Watermarking Scheme For Tamper Detection and Recovery of Image
2006 6th World Congress on Intelligent Control and Automation, 2006A fragile, block-wise, and content-based watermarking scheme for tamper detection and recovery of image is presented. In the scheme, an image is divided into four quadrants firstly. Then correlation groups are set up after some blocks (each size is 8times8) in different two quadrants being matched. Correlative matrix can be got after the blocks of each

A New Image Watermarking Scheme for Efficient Tamper Detection, Localization and Recovery
2019 IEEE International Conference on Multimedia & Expo Workshops (ICMEW), 2019Due to the powerful image editing tools, image integrity protection is becoming important, for instance, in a court of law, news reports, insurance claims or telemedicine. Digital image watermarking is a technique to detect, localize and recover tampered image but the accuracy of performance by the existing methods is still an issue.

SVD based fragile watermarking scheme for tamper localization and self-recovery
International Journal of Machine Learning and Cybernetics, 2015This paper proposes a novel fragile watermarking approach for digital image tamper localization (TL) along with the self-recovery (SR) capability. The host image is first divided into blocks of size 4 × 4 and then, singular value decomposition is performed on each block. The trace of singular matrix is used to compute the TL bits for each block.

Evaluation of Medical Image Watermarking with Tamper Detection and Recovery (AW-TDR)
2007 29th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2007This paper will study and evaluate watermarking technique by Zain and Fauzi [1]. Recommendations will then be made to enhance the technique especially in the aspect of recovery or reconstruction rate for medical images. A proposal will also be made for a better distribution of watermark to minimize the distortion of the Region of Interest (ROI).

A Novel Tamper Detection and Image Recovery Technique for Color Image Demosaicking
2018In this paper, we designed an image integrity protection technique for color image demosaicking. In the proposed technique, the authentication codes are generated based on the random values induced by the random number seed. The recovery codes are generated by compressing the demosaicked image using the block truncation coding technique.
