A bit toggling approach for AMBTC tamper detection scheme with high image fidelity.
PLoS ONE, 2020 The existing tamper detection schemes for absolute moment block truncation coding (AMBTC) compressed images are able to detect the tampering. However, the marked image qualities of these schemes can be enhanced, and their authentication methods may fail ...

A two-stage detection method of copy-move forgery based on parallel feature fusion
EURASIP Journal on Wireless Communications and Networking, 2022 The copy-move forgery refers to the copying and pasting of a region of the original image into the target region of the same image, which represents a typical tampering method with the characteristics of easy tampering and high-quality tampering.

Surveillance Footage Video Tampering Detection
Informatica : Journal of Applied Machines Electrical Electronics Computer Science and Communication Systems, 2020 The quality of the captured images was enhanced by some of the first digital video and image processing applications, but as the power of computers expanded, so did the number of applications where video and image processing could make a difference. Video and image processing are used in many different applications nowadays.

Detecting Test Tampering Using Item Response Theory [PDF]
Educational and Psychological Measurement, 2015 Test tampering, especially on tests for educational accountability, is an unfortunate reality, necessitating that the state (or its testing vendor) perform data forensic analyses, such as erasure analyses, to look for signs of possible malfeasance. Few statistical approaches exist for detecting fraudulent erasures, and those that do largely do not ...

Quantum Security for the Physical Layer [PDF]
, 2013 The physical layer describes how communication signals are encoded and transmitted across a channel. Physical security often requires either restricting access to the channel or performing periodic manual inspections.
