Forensics and counter anti-forensics of video inter-frame forgery
Multimedia Tools and Applications, 2015Among different types of video manipulations, video inter-frame forgery is a powerful and common tampering operation. Several forensic and anti-forensic techniques have been proposed to deal with this challenge. In this paper, we first improve an existing video frame deletion detection algorithm.

Median Filtering Forensics in Compressed Video
IEEE Signal Processing Letters, 2019Median filtering has received extensive attention from forensics analyzers, as a common content-preserving, smoothing, and denoising manipulation. We propose a detection scheme for median filtering of video sequences in compressed domain based on the singular value decomposition of the process matrix , which approximates the median filtering ...

Proceedings of the ACM 2nd international workshop on Video surveillance & sensor networks, 2004
This paper describes an application that enables quick reconstruction of interconnected events, sparsely captured by one or more surveillance cameras. Unlike related efforts, our approach does not require indexing, advance knowledge of potential search criteria, nor a solution to the generalized object-recognition problem.

Image and Video Forensics: A Critical Survey
Wireless Personal Communications, 2020With the extensive use of multimedia on internet and easy approachability of powerful image and video editing software, doctored visual contents have been extensively appearing in our electronic-mail in-boxes, Whatsapp, Facebook or any other social media. Recently, attempting blind tampering in visual contents have been progressively adopted.

Video digitali in ambito forense
Ciberspazio e diritto : Internet e le professioni giuridiche : 11, 4, 2010, 2010La crescente diffusione di dispositivi di imaging a basso costo e la conseguente disponibilita di grosse quantita di foto e filmati digitali rende l’attivita investigativa e di verifica su tali supporti sempre piu frequente. Solo nel mondo virtuale della Rete stime recenti aggiornate a meta del 2009 indicano in circa 4 miliardi il numero di foto ...

Video forensics based on expression dynamics
2014 IEEE International Workshop on Information Forensics and Security (WIFS), 2014Digital graphics tools are nowadays capable of rendering highly photorealistic imagery, which easily puzzle our perception of reality. This poses serious ethical and legal issues, which in turn create the need for further technologies able to ensure the trustworthiness of digital media as a true representation of reality, especially when depicting ...

Video condensation for video forensics
2012 IEEE International Conference on Computational Intelligence and Cybernetics (CyberneticsCom), 2012Video forensics has become an important issue because of the setup of a large number of surveillance cameras. Video condensation can increase efficiency in quickly searching criminal events from the vast amounts of surveillance video data. In this paper, we propose a video condensation technique for video forensics to condense a long period of ...

At forensic laboratories, cases are submitted for forensic investigation of videotapes and recorders. The video investigation is often requested by the court for different types of crime, like robberies and homicides. For these investigations, most laboratories use a computer to digitize the images uncompressed in such that they try to minimize the ...

Image and video fingerprinting: forensic applications
SPIE Proceedings, 2009Fighting movie piracy often requires automatic content identification. The most common technique to achieve this uses watermarking, but not all copyrighted content is watermarked. Video fingerprinting is an efficient alternative solution to identify content, to manage multimedia files in UGC sites or P2P networks and to register pirated copies with ...
