On Resampling Detection and its Application to Detect Image Tampering [PDF]
Usually digital image forgeries are created by copy-pasting a portion of an image onto some other image. While doing so, it is often necessary to resize the pasted portion of the image to suit the sampling grid of the host image. The resampling operation changes certain characteristics of the pasted portion, which when detected serves as a clue of ...

Detecting digital tampering by blur estimation [PDF]
With powerful computer and mighty software, seasoned users could turn digital media into what they want. The detection of digital tampering has become a crucial problem. In most of the time, digital tampering is not perceptible by human: however, some traces of digital tampering may be left in the media during the process.

Speaker Inconsistency Detection in Tampered Video [PDF]
With the increasing amount of video being consumed by people daily, there is a danger of the rise in maliciously modified video content (i.e., ‘fake news') that could be used to damage innocent people or to impose a certain agenda, e.g., meddle in elections.

Attack characterisation of compressed images [PDF]
We propose the use of robust watermarks to enable the characterisation of attacks even after lossy compression, such as JPEG and JPEG2000. A previously constructed Bayesian framework is used to allow characterisation of attacks from a predetermined ...

Region‐based scalable self‐recovery for salient‐object images
Self‐recovery is a tamper‐detection and image recovery methods based on data hiding. It generates two types of data and embeds them into the original image: authentication data for tamper detection and reference data for image recovery.
