Technology:
Major IT companies are
accelerating their efforts to develop technologies for anticrime measures
toward the Tokyo Olympics in 2020. Hitachi developed a technology to detect a
person who handled an explosive when he passes through the ticket gate of railway
stations, and NEC developed a system to pinpoint a suspect while monitoring the
city streets by combining image processing technology and security camera and
put it into practical use.
Hitachi’s system puts a device to blow
warm and an analyzing device of fine particles of an explosive to the ticket
gate. When a passenger puts his IC card on the ticket gate, warm air instantly
is sprayed to his hand. The device instantly draws in and analyses fine
particles attached to the hand instantly. When the fine particles agree with
the substances of an explosive, the device gives an alarm and closes the ticket
gate. It works with an image processing system that uses security camera to
chase the person even in the crowd. The company plans to put the technology
into practical use by 2018 in time for the Tokyo Olympics.

NEC developed a crime-prevention system
that can monitor the whole city using NEC’s high precision image recognition
technology. NEC’s system has the world highest precision of image recognition technology,
and it can recognize a face at such a high success rate of 96%. The company has
already shipped the system to Tigre, a resort northwest of Buenos Aires in
Argentine. The system shipped to the resort has 1,000 cameras to cover an area
of 150 square kilometers, and it works with the database of the police
department. The system is managed by a private security company, but the police
department dispatches police officers as soon as it receives a report from the security
company. It has the function to detect the number places of stolen cars.

A research company in Japan
estimates that the world market of image processing system will grow to 70
million yen in 2017.
