The new technology predicts events with an accuracy of 82.8%.
A team of South Korean researchers has developed a new technology capable of detecting and predicting criminal activities using artificial intelligence (AI) and data from security cameras in real time. The new system significantly expands the traditional role of video cameras, making them not only a tool for surveillance, but also an effective means of preventing crime.
The Electronics and Telecommunications Research Institute (ETRI) recently announced the completion of Dejaview, an innovative technology that uses surveillance footage, crime statistics and location technology to identify signals of potential crimes and predict the likelihood of them occurring.
The basic approach of the Dejaview system is based on the fact that crimes are often repeated according to certain patterns - by type, place, time and method of commission. The developers focused on identifying these recurring patterns. The AI system compares current conditions with data from previous incidents to predict the likelihood of a crime being committed.
The Dejaview technology is divided into two main categories depending on the purpose of application and the method of analysis. The first category is a technology for predicting crimes focused on time and space. It analyzes the probability of the occurrence of criminal acts depending on time and place. For example, if similar conditions are observed in a remote and quiet area where crimes have previously occurred at night, the system determines a high risk of a re-incident. Thus, it helps prevent crime by strengthening security measures in such places.
The Dejaview system is planned to be used by the police and CCTV control centers in various regions of the country. AI analyzes the real picture from cameras in real time and compares it with past crime cases to identify and prevent potential threats such as stalking, theft, fires, or drug trafficking. ETRI also said that the system will allow you to quickly respond to situations, helping to track suspicious activity.
In cooperation with the Soucho-gu district of Seoul, the institute developed a crime forecasting map (PCM). To create it, more than 32 thousand videos from 2018 were analyzed, which recorded various incidents. The map was divided into zones by time, place and type of incidents to identify areas with the highest likelihood of criminal activity. The risk level for each zone is displayed on the screen in real time, allowing CCTV operators to focus on the most dangerous areas.
According to the data obtained during testing, the accuracy of predicting crimes using the PCM card was 82.8%.
The second key technology of the Dejaview system is focused on predicting relapses. It allows you to assess the risk of re-committing a crime by persons under supervision based on an analysis of their movements and behavior. Currently, the electronic control system only records violations of the movements of such persons, based on location data. ETRI technology is able not only to track a person's movements, but also to analyze their behavior, which will allow them to more accurately determine the risk of relapse.
In the future, ETRI plans to improve "Dejaview" to integrate it into various security systems. The plans include the development of specialized solutions for the protection of key infrastructure facilities, such as airports, energy and manufacturing enterprises, as well as the creation of security systems for large events and personal protection services.
This requires the further development of AI technologies that can accurately analyze visual data coming from CCTV cameras in real time. Based on the collected data, systems will be created that will be able to prevent dangerous situations and prevent crimes. There are also plans to develop electronic monitoring systems to control the behavior of persons under surveillance.
Commercial use of the Dejaview technology is scheduled for the end of next year. According to Kim Gong-woo, a senior researcher at ETRI's AI and Security Convergence Division, the institute has managed to create a video security technology that uses information from CCTV cameras to prevent crimes. The developers are confident that this technology will become the basis for the future public safety system.
As the technology evolves, researchers will collaborate with local authorities and organizations to provide services to detect signs of crime and predict threats to a variety of facilities and targets.
