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

Towards a Forensic Analysis for Multimedia Communication Services [PDF]
2011 IEEE Workshops of International Conference on Advanced Information Networking and Applications, 2011 No matter how robust the employed security mechanisms are malicious users or attackers will always find a way to bypass them. In addition, National Institute of Security and Technology mentions "In conjunction with appropriate tools and procedures, audit trail can assist in detecting security violation and flaws in applications".

A Cross‐Disciplinary Analysis of AI Policies in Academic Peer Review
Learned Publishing, Volume 39, Issue 1, January 2026.ABSTRACT Rapid advances of artificial intelligence (AI) have substantially impacted the field of academic publishing. This study examines AI integration in peer review by analysing policies from 439 high‐ and 363 middle‐impact factor (IF) journals across disciplines. Using grounded theory, we identify patterns in AI policy adoption. Results show 83% of

IET Image Processing, Volume 20, Issue 1, January/December 2026.This paper presents a robust reversible watermarking algorithm based on Chebyshev moments, employing a two‐stage embedding mechanism. The proposed method leverages image block partitioning to embed the copyright watermark and the reversible watermark into non‐overlapping regions located inside and outside the inscribed circle of the image, respectively.

IET Image Processing, Volume 20, Issue 1, January/December 2026.This study proposes a GAN‐generated image forgery detection method that integrates error level analysis (ELA) with advanced CNN‐based transfer learning models, achieving 96.37% accuracy. Additionally, we introduce the HFD‐8000 dataset, a novel and publicly available collection of 8,000 original and forged images, to address the scarcity of GAN‐specific

Power Signature for Multimedia Forensics
, 2022 AbstractThere has been an increasing amount of work surrounding the Electric Network Frequency (ENF) signal, an environmental signature captured by audio and video recordings made in locations where there is electrical activity. ENF is the frequency of power distribution networks, 60 Hz in most of the Americas and 50 Hz in most other parts of the world.

Just Dance: detection of human body reenactment fake videos
EURASIP Journal on Image and Video ProcessingIn the last few years, research on the detection of AI-generated videos has focused exclusively on detecting facial manipulations known as deepfakes. Much less attention has been paid to the detection of artificial non-facial fake videos.

Image Manipulation Detection and Localization Based on the Dual-Domain Convolutional Neural Networks
IEEE Access, 2018 In multimedia forensics, many efforts have been made to detect whether an image is pristine or manipulated with high enough accuracies based on specially designed features and classifiers in the past decade. However, the important task for localizing the
