This is the fourth installment of a series that uses the Olympics to take a fresh look at the past and future of the nation.

 reports: Advanced technologies that use artificial intelligence, or AI, are likely to be introduced to help detect terrorists as part of security for the 2020 Tokyo Olympics and Paralympics.

Police have marked the second Tokyo Olympics as the “first year of high-tech security,” and are seeking next-generation security that integrates people and technology to identify terrorists in large crowds.

A person’s face while standing in front of a camera turns red when seen through a monitor. The major security giant Sohgo Security Services Co., known as ALSOK, has started operating its emotion visualization system. AI measures a person’s psychological state based on small tremors that the body exudes, the width of those tremors and so on. It displays the person’s mental state by assigning numerical values and colors, and “aggressiveness” is indicated when the color turns red. Terrorists are said to tremble when their emotions rise just before committing an act of terrorism.

The system was developed by a Russian company. ALSOK introduced it on a test basis at the baggage inspection site at the summit meeting of the Group of Seven major countries (the Ise-Shima summit) held in May last year. Although there were no suspicious people, the system detected irritated people who were waiting in line for inspections.

“In the next three years, we want to sharpen up the accuracy of the system,” said a company spokesperson.

Secom Co. conducted a feasibility experiment during the Tokyo Marathon in February, featuring a new system using AI that predicts terrorism.

If the computer studies situations where terrorism and other incidents are likely to happen and it detects a suspicious object or a person’s unnatural movements, it could be a sign of terrorism. That triggers the company’s security headquarters alarm. The company is aiming for practical application of the system at the Tokyo Games.

Mitsubishi Electric Corp. developed a system that predicts congestion after 10 minutes by capturing the flow of people with cameras installed along the roads. The company has already started experimenting at firework festivals, among other events, and it has been effective in guiding spectators.

The 1964 Tokyo Olympics were focused on preventing confrontations related to the Cold War among participating countries, as well as keeping a watch on crowds. The threat of international terrorism looms over the upcoming Games in 2020.

“We want security to leave a legacy also by incorporating the latest established technology,” said Katsunori Imai, chief of the Security Bureau at the Tokyo Organizing Committee of the Olympic and Paralympic Games.

The Tokyo Olympics held 53 years ago were deemed “the first year of private security.”

More than 100 security guards of Japan’s first private security firm, Nihon Keibi Hosho (now Secom Co.), founded in 1962, were assigned to keep guard of the Olympic Village in 1964. It was the first time for a private company to handle security at a public event.

Public awareness of private security was limited back then, and … (read more)
