Computer analyzes suspicious behavior

Amsterdam, April 23, 2013

Pick pocketing, shoplifting, aggression and antisocial behaviour. The security industry want so prevent it, if possible, or at least be there as quickly as possible to intervene. Led by TNO, together with 3 SME's and a freelancer, are working together to develop a system for using computer analysis and camera images to identify suspicious behaviour. Soon, a pilot project with this system will start in Utrecht.

The group, called "Watching People Security Services”, analyzes the way people walk via the computerized system. Deviations from the “normal” pattern could, for example, indicate a pickpocket, aggression or someone who intends to commit shoplifting can. A security guard evaluates what is going on, because not everyone who is remaining somewhere longer than normal is preparing a robbery, he might just make a phone call.

Time consuming

In order to monitor the behaviour of people, many places in The Netherlands have cameras hanging which are being monitored by security guards. If computers take over this time consuming activity, the result is that time is significantly saved.


In order to predict the behaviour an algorithm is needed to ensure that computers can follow people that are in the picture on various surveillance cameras. Next to that the system should be able to detect weapons and analyze suspicious behaviour. In the end, the security guard will examine the situation as normal or as suspicious and ready to act.

The consortium, next to TNO consists of; Vicar Vision, Eagle Vision, Noldus IT, and freelancer John Borking Consultancy. JBC is a privacy law expert and will consider the privacy issues around the implementation and execution of the project. The group will start the pilot of this project in the autumn, in the shopping mall of Kanaleneiland in Utrecht.
