Image watermarking for tamper detection
Proceedings 1998 International Conference on Image Processing. ICIP98 (Cat. No.98CB36269), 2002We 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.

A Survey of Passive Image Tampering Detection
Lecture Notes in Computer Science, 2009Digital images can be easily tampered with image editing tools. The detection of tampering operations is of great importance. Passive digital image tampering detection aims at verifying the authenticity of digital images without any a prior knowledge on the original images. There are various methods proposed in this filed in recent years. In this paper,

Multi-level tamper detection and recovery with tamper type identification
2013 IEEE International Conference on Image Processing, 2013A fragile watermarking scheme with simple and effective tamper detection and recovery capability is proposed in this paper. In this new scheme, not only one parity-check watermark but also two copies of feature-bit watermark are embedded. For tamper detection, a new multi-level tamper detection strategy including intra-block detection, inter-block ...

Tamper Detection and Recovery on RGB Images
2020Special devices are required to perform tampering on an analogue image. This requires a serious cost and skill. But it is easy to tamper on a digital image. Digital images can be tampered even with easy accessible free digital image editing software. Moreover, this tampering can occur even with a mobile phone.

Detection and Restoration of a Tampered Medical Image
2004This paper presents a recoverable image tamper proofing technique using the symmetric key cryptosystem and vector quantization for detecting and restoring of a tampered medical image. Our scheme applies the one-way hashing function and the symmetric key cryptosystem to the host image to generate the verification data.

Tamper detection for active surveillance systems
2013 10th IEEE International Conference on Advanced Video and Signal Based Surveillance, 2013If surveillance data are corrupted they are of no use to neither manually post-investigation nor automatic video analysis. It is therefore critical to automatically be able to detect tampering events such as defocusing, occlusion and displacement. In this work we for the first time address this important problem for an active camera.
