Issues of Using AI Technology as a Surveillance Technology – Japan as an Example

AI recognition technology is evolving. And machines and robots utilizing various AI recognition technologies have now been more developed for disaster prevention, monitoring, and surveillance. The recognition technology includes facial recognition. In Japan, JR East began using facial recognition technology in July 2021 to detect a portion of released and parolees inside stations. Media found about the system in September 2021 with sharp criticism and then JR withdrew the proposal, saying that a social consensus had not yet been reached. Certainly, it would be convenient for public transportation, including railway companies, to use AI technology, including facial recognition, to prevent problems and prevent disasters. However, in this paper, the author argues that the utilization of AI technology for surveillance has major problems from the viewpoint of human rights protection and Personal Information Protection Law, thus the usage must be restrained and properly regulated by law.
