Enhanced Detection of GAN‐Generated Image Forgeries Using Error Level Analysis and Deep Learning Models

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

An Evaluation of Popular Copy-Move Forgery Detection Approaches

, 2012
A copy-move forgery is created by copying and pasting content within the same image, and potentially post-processing it. In recent years, the detection of copy-move forgeries has become one of the most actively researched topics in blind image forensics.

Secure Live Streaming: Implementing Security in Adaptive Video Streaming via Watermarking Techniques While Preserving Quality

International Journal of Digital Multimedia Broadcasting, Volume 2026, Issue 1, 2026.
The heterogeneity of the network at the edge creates unequal bandwidth availability for clients connected through diverse networks and devices. This variability can lead to bandwidth fluctuations and slow response times, resulting in buffering or degraded streaming performance.

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
