Forensic of video object removal tamper based on 3D dual-stream network

Tongxin xuebao, 2021
In order to solve the problems of inaccurate temporal detection and location of the object removal tampered video， a video tamper forensics method based on 3D dual-stream network was proposed.Firstly， the spatial rich model （SRM） layer was used to ...

On Second Thought: The Impact of Confessions, DNA, and Belief Perseverance on Students' Perceptions of Guilt and Interrogations

Behavioral Sciences &the Law, Volume 44, Issue 3, Page 373-387, May/June 2026.
ABSTRACT Despite growing public knowledge of false confession cases, research with students and community members continues to find that people assume confessions indicate guilt. The present research explored the implications of belief perseverance: the tendency to maintain a belief even when confronted with compelling contradictory evidence.

Forensic analysis of video file formats

Digital Investigation, 2014
AbstractVideo file format standards define only a limited number of mandatory features and leave room for interpretation. Design decisions of device manufacturers and software vendors are thus a fruitful resource for forensic video authentication. This paper explores AVI and MP4-like video streams of mobile phones and digital cameras in detail.

Anti- Forensics: The Tampering of Videos

International Journal of Forensic Sciences, 2021
In the context of forensic investigations, the traditional understanding of evidence is changing nowadays where most prosecutors, lawyers and judges heavily rely on multimedia substantiations. However, the evolution of easy-to-use media manipulating tools, made it very easy for almost any (technical) person to alter the content of a digital media (e.g.

CNN-Based Multi-Modal Camera Model Identification on Video Sequences

Journal of Imaging, 2021
Identifying the source camera of images and videos has gained significant importance in multimedia forensics. It allows tracing back data to their creator, thus enabling to solve copyright infringement cases and expose the authors of hideous crimes.

Provenance Filtering for Multimedia Phylogeny

, 2017
Departing from traditional digital forensics modeling, which seeks to analyze single objects in isolation, multimedia phylogeny analyzes the evolutionary processes that influence digital objects and collections over time.

Filtering Trust: Disclosing the Role of Artificial Intelligence Decreases Trust in Technology, but Does Not Prevent Harm to Body Image After Viewing AI‐Generated Content

International Journal of Eating Disorders, Volume 59, Issue 6, Page 1304-1312, June 2026.
ABSTRACT Objectives Despite the rapid growth of generative artificial intelligence (AI), virtually no research exists examining the psychological impacts of viewing or interacting with AI‐generated images of people. Additionally, it remains relatively unknown whether informing viewers when images are AI‐generated is an effective way to lessen harm or ...

TFD-Video: Threshold-Aware Federated Deepfake Detection for Video Forensics

IEEE Access
Deepfakes and other AI-based manipulated and synthesized videos pose a rising threat, yet training robust detectors under federated settings is challenging, where data is siloed and communication is limited.

Video surveillance and multimedia forensics

Proceedings of the First ACM workshop on Multimedia in forensics, 2009
This paper reports an example of application (i.e., trajectory analysis) in which forensics and video surveillance techniques are jointly employed for providing a new tool of multimedia forensics. Advanced video surveillance techniques are used to extract from a multi-camera system the trajectories of the moving people which are then modelled by either
