NTT Com Develops Secure Access System with Human Area Networking Technology

TOKYO, JAPAN - NTT Communications Corporation (NTT Com) announced today that together with Hitachi, Ltd. and MIWA LOCK Co., Ltd. it has developed a new human-identification system using RedTacton, a Human Area Networking technology developed by Nippon Telegraph and Telephone Corporation that uses the surface of the human body as a safe, high-speed network transmission path.

RedTacton uses a transmission path established between the body of a person carrying a RedTacton card key and a RedTacton transceiver installed in, for example, a doorknob or floor.
The person is automatically identified when they touch the doorknob or walk on the floor, and the transmission path is disconnected when the body and transceiver physically separate.

Security demands are increasing in virtually every industry of Japan after passage of compliance legislation similar to the U.S. Sarbanes-Oxley Act. Companies have also been seeking less obtrusive systems for secure access, since conventional systems require a contactless IC card to be waved over a terminal.

RedTacton enables a defined spot to serve as the point of identification, whereas wireless and infrared communication require wider areas. Identification points can be installed along the main areas of movement within a building, thereby enabling repeated identification of people as they enter a secure area, move about it and then exit. RedTacton is also highly scalable for systems incorporating flapper gates, finger-vein authentication devices, immersion-detection sensors or safety equipment.

NTT Com designed and constructed the system and manufactured the RedTacton card key and reader. Hitachi designed the access management system and manufactured related management and control devices. MIWA LOCK designed and manufactured the RedTacton-equipped doorknob.

NTT Com will now begin promoting the new system for use by research facilities, data centers and factories that require high security or cleanliness. Hitachi will demonstrate the system at Security Show 2009, which will take place at the Tokyo Big Sight exhibition complex from March 3 to 6.
