Authentication Service using PUF Authentication RFID
■ Summary of the authentication service using unclonable RFID
Our company has been involved in printing technologies for many years, but in addition, we have used our experience in ID creation and utilization, strengthening of ICT environments and evolution of NFC technologies to develop our new PUF Authentication Service, a new authentication/authorization service.
Products are affixed with a SMARTICS-V RFID chip with PUF functionality, and product purchasers are able to use a PUF authentication app installed on their own NFC-compatible smartphones to read the chip. Online connectivity makes it possible for anyone to simply and quickly check authenticity.
When the IC chips in the SMARTICS-V RFID used in this service are produced, a fine random pattern is generated that makes the RFID authenticatable but unclonable.
■ What is PUF?
PUF stands for Physical Unclonable Function, which introduces fine, random differences into IC chips when they are being made.
We have commercialize Silicon PUF, which utilizes the fine differences between semi-conductors.

Authenticating an NFC-compatible IC chip with Silicon PUF technology.
◆IC Chip Features
①Low prices possible because complex cipher circuits are unnecessary.
(Similar in cost to non-secure RFIDs.)
②Physical characteristics of a circuit’s structure cannot be copied, making duplication virtually impossible.
③No cryptographic keys are stored internally, so there is no risk of keys being leaked.
◆ Authentication System Features
① Consumers can use their own smartphones for authentication. No specialized equipment required.
② Authentication is conducted over the internet making the system usable worldwide. (Support for nine languages in the dedicated app.)
③ Server authentication is implemented through the IC chip (using mutual authentication) making the system highly secure.
■ The Authentication Process (Simplified)
■ Increasing user-friendliness from authentications
By allowing users to authenticate a purchased product using their own smartphones, user information can be collected and sent using various CRM menus, so a direct line of communication to purchasers can be built.

Metal pallet management system: Komatsu Logistics Corporation
To get real-time visibility of usage, prevent theft and loss, and optimize deployment of metal pallets for construction equipment parts, Komatsu has attached RFID tags to the pallets. They have been tracking tagged pallets travelling between Japan, the UK, Indonesia, and China by using a Web server integrating tag data.

Automated management of the remaining amount of material and the inventory has reduced workloads and prevented failure of filling.
Realizing zero-emissions at housing construction sites-waste management: Sekisui House, Ltd., The Japan Research Institute, Limited (Ministry of Land, Infrastructure, Transport and Tourism -subsidized projects(*4))
RFID tags are attached on containers of waste at housing construction sites. The system manages the information (weight, type and site name of waste) to collect 100% of waste.

Participants who receive the entrance cards are able to realize interactive communication with various equipment such as monitors, robots, etc.
FusionWorld is an interactive and multi-sensory showcase gallery of technologies from A*STAR's research institutes. The 700 sqm smart environment is segregated into five thematic zones - Home, Enterprise, Medical, Move and Lounge. The chief aim is to enhance R&D by demonstrating how companies can leverage on A*STAR's technologies to develop new products, markets and business models.
Fusionopolis, a science and technology powerhouse for Singapore, brings together, under one roof, research scientists, engineers and technology experts from the public labs of the Agency for Science, Technology and Research (A*STAR) and those from the private sector.

Point rally system: Shogakukan-Shueisha Productions Co., Ltd.
At an event hosted by Shogakukan-Shueisha Productions Co., Ltd., RFID tags were used for a treasure hunting game. Participants collected points at each booth and enjoyed a lottery.
