Digital Forensics: Focusing on Image Forensics
2019 7th International Symposium on Digital Forensics and Security (ISDFS), 2019The world is continuously developing, and people's needs are increasing as well; so too are the number of thieves increasing, especially electronic thieves. For that reason, companies and individuals are always searching for experts who will protect them from thieves, and these experts are called digital investigators. Digital forensics has a number of

Image acquisition forensics: Forensic analysis to identify imaging source
2008 IEEE International Conference on Acoustics, Speech and Signal Processing, 2008With widespread availability of digital images and easy-to-use image editing softwares, the origin and integrity of digital images has become a serious concern. This paper introduces the problem of image acquisition forensics and proposes a fusion of a set of signal processing features to identify the source of digital images. Our results show that the

Image Forensics in Online News
2018 IEEE 20th International Workshop on Multimedia Signal Processing (MMSP), 2018Recognizing fake images in online news is a challenging problem. This is especially true in the case of critical situations, when journalists might insert high-impact images to make a piece of news more appealing to the readers, neglecting to check their authenticity and provenance.

A review of digital image forensics
Computers & Electrical Engineering, 2020Abstract The manipulation of digital images has become very common in recent years. Thus, it is possible to cut, clone, and resize an image very quickly, which makes it challenging to validate the integrity and authenticity of images. Furthermore, digital images can be used by forensic experts in their forensic investigations.

Characteristics of Forensic Imaging Performance—An Analysis of Forensic Imaging Bottlenecks
Journal of Forensic Sciences, 2013AbstractDisk imaging involves copying all of the data from a source disk drive to a target. Typically, the target for the copy is another disk drive. Forensic processes developed years ago do not appear to be adequate for current storage technology. For example, with disk drive capacities now exceeding 1 Terabyte, a typical disk imaging can take over 8
