Tampering Detection and Restoration of Compressed Video
2018 15th International ISC (Iranian Society of Cryptology) Conference on Information Security and Cryptology (ISCISC), 2018This paper presents a method to detect tampering of video data and then restore an approximate version of its original contents in compressed H.264/AVC domain using watermarking. In the proposed scheme, a low resolution image from a number of video frames in certain time slots are embedded into the DCT coefficients of the other parts of the video which

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.

A signal detection theory approach for camera tamper detection
2017 14th IEEE International Conference on Advanced Video and Signal Based Surveillance (AVSS), 2017Camera tamper detection is the ability to detect faults and operational failures in video surveillance cameras by analyzing the video. Researchers have increasingly focused on such techniques attributing to the ubiquitous deployment of large scale surveillance systems.

Image tamper detection based on demosaicing artifacts
2009 16th IEEE International Conference on Image Processing (ICIP), 2009In this paper, we introduce tamper detection techniques based on artifacts created by Color Filter Array (CFA) processing in most digital cameras. The techniques are based on computing a single feature and a simple threshold based classifier. The efficacy of the approach was tested over thousands of authentic, tampered, and computer generated images ...

Detection of Tampering Inconsistencies on Mobile Photos
2011Fast proliferation of mobile cameras and the deteriorating trust on digital images have created needs in determining the integrity of photos captured by mobile devices. As tampering often creates some inconsistencies, we propose in this paper a novel framework to statistically detect the image tampering inconsistency using accurately detected ...

Medical Image Watermarking with Tamper Detection and Recovery
2006 International Conference of the IEEE Engineering in Medicine and Biology Society, 2006This paper discussed security of medical images and reviewed some work done regarding them. A fragile watermarking scheme was then proposed that could detect tamper and subsequently recover the image. Our scheme required a secret key and a public chaotic mixing algorithm to embed and recover a tampered image. The scheme was also resilient to VQ attack.

Tampering Detection in Low-Power Smart Cameras
2015A desirable feature in smart cameras is the ability to autonomously detect any tampering event/attack that would prevent a clear view over the monitored scene. No matter whether tampering is due to atmospheric phenomena (e.g., few rain drops over the camera lens) or to malicious attacks (e.g., occlusions or device displacements), these have to be ...
