Sexual violence, domestic violence, and stalking crimes are serious social issues that contribute to a continual rise in the annual number of individuals seeking protective measures for “personal safety” from the police. Although protective measures for personal safety are actions taken to prevent potential crimes. However, as the crime rate among protected individuals has increased more than threefold from an average of 7% over the past three years(2018 to 2020) to 21% in 2023, doubts about the effectiveness of the current “personal safety” measures have been raised. 88% of the individuals under protective measures are either female or the socially vulnerable class in need of social protection. However, instances of individuals under protective measures being exposed to the danger of serious crimes such as assault and murder have recently seen a significant increase. Under the existing system, the apprehension of the suspect is done after a crime is committed, making it an ex post facto response taken after significant, irreversible damage is caused to the victim. Consequently, there has been a call for a victim-centered approach to detect early signs of crime and prevent crime.
The Ministry of Science and ICT proposed collaboration with the NPA to enhance preventive measures by the video analysis capabilities of Smart CCTV. This collaboration aims to help victims recognize early signs of crimes, such as loitering, illegal intrusion attempts, and lurking, which could cause secondary harm, enabling victims to avoid potential dangers. KISA is an institution that developed the world’s second Smart CCTV performance verification technology and is responsible for conducting relevant testing and certification. Each year, KISA has continued to enhance the Smart CCTV technology for disaster prevention and crime prevention.
The stalking crime prevention technology powered by Smart CCTVs has the following innovative aspects.
The phases of the innovation:
The technology to analyze video footage taken from super-short-ranges had not been widely used. Therefore, there was the need for extensive real-world training data to enhance the performance of the technology in the private sector. However, due to issues such as compliance with the Personal Information Protection Act, the use of real-world video data was not possible. To resolve this issue, KISA, the NPA, and 18 local police agencies joined forces to develop 1,300 probable scenarios and construct the real-world video database.
Even after successfully developing the technology and enhancing its performance, it was crucial to ensure its performance in real-world settings, not just in the lab environment. To this end, typical residence types for stalking victims (multi-unit housing, apartments, etc.) were identified, and the solution ready for immediate implementation was developed through on-site demonstrations. The on-site demonstrations contributed to improving the performance, identifying and resolving real-world issues.
This innovative technology can be applied and utilized in any country and environment. The caveat is that the data required to train the AI technology varies depending on the spatial elements (wide hallways, backyard, etc.) and environmental factors (fog, rain, snow, etc.). This challenge can be met by developing and demonstrating diverse training data. Recently, street assaults, dating violence, and stalking have emerged as serious issues. KISA hopes this technology will be widely adopted globally, thereby preventing harm and protecting many people.
The public sector in the Republic of Korea has installed and operates around 1.65 million CCTV cameras. According to statistics, each person in South Korea is exposed to about 18 different CCTV cameras per day. By integrating AI into the extensive public infrastructure, we aim to develop technology aimed at preventing various accidents or crimes.
