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.

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 ...

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 ...

Video authentication in digital forensic
2015 International Conference on Futuristic Trends on Computational Analysis and Knowledge Management (ABLAZE), 2015The large amount of video content is being transmitted over internet and other channels. With the help of existing multimedia editing tools one can easily change the content of data which lead to lose the authenticity of the information. Thus, it becomes necessary to develop different methods by which the authenticity of the videos can be confirmed. In

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 ...

Forensic uses of infrared video
Proceedings 1992 International Carnahan Conference on Security Technology: Crime Countermeasures, 2003A comprehensive investigation of the commercial applicability of infrared technology has been conducted. While the main focus of these efforts has been evaluation of technology applicable to an infrared facial identification system, the availability of imaging and image processing equipment has made it possible to assess the use of infrared systems and

Proceedings of the 2nd ACM workshop on Multimedia in forensics, security and intelligence, 2010
Identifying videos on seized hard drives and other storage devices is a very tedious and time consuming task for forensic investigators. In particular, the vast amount of available material on the Internet and the large storage capacities of today's hard drives have become a strong headache for them.

Multimedia content is more accessible than ever before due to a variety of factors including more advanced compression techniques, higher throughput channels, and an increase in media sharing hardware and software. The ease with which people can send and receive media is associated with an increase in the amount of false or misleading media being ...

The PRNU Algorithm of Video Forensics
Digital Forensics (4n6) Journal, 2020The A video sequence provides more proof of an occurring event than a photo or a group of photos. Hence it is important to identify the source of the video. In this paper, we explore how the Photo Response Non-Uniformity (PRNU) noise is useful for the detection of source cameras- Metadata of a Camera.
