Japan's Toppan Forms Uses Keychain Core to Secure Healthcare Data over IoT and Cloud

TOPPAN FORMS CO.,LTD. (Locate: Minato-ku, Tokyo, President: Koichi Sakata, hereunder “Toppan Forms”) and a leading blockchain company, Keychain GK (Locate: Minato-ku, Tokyo, CEO: Hope Jonathan, hereunder “Keychain”) have confirmed the effectiveness of the experiment Proof of Concept (PoC) by using blockchain for device authentication and sharing medical data.

Overview

Toppan Forms and Keychain signed a strategic partnership agreement on Wednesday, April 1, 2020 to promote the use of blockchain on IoT field.

As the first joint step, Toppan Forms used Keychain's Core solution accelerator product to deploy an application that shares data between IoT devices and the cloud. Toppan Forms collaborated with its Osaka Sakurai Factory on a PoC to share medical health vital signs related to emotional stress from wearable device, through IoT gateway, and to cloud system. Keychain's unique data security capabilities enabled Toppan Forms to achieve new levels of security in healthcare applications.

By using blockchain as authentication management, while encrypting data on existing system, this hybrid blockchain approach enabled high-speed and light weight software based authentication platform and system. We confirmed that the platform system achieved edge device level security.

Confirmed Effectiveness

1. Data is not recorded on the blockchain and only use for device P2P authentication, and achieved high-speed and lightweight applications on devices. Application can be embed on low-spec devices such as IoT gateways.

2. Data is encrypted and not on blockchain. It enable secure data communication without disclosing transaction record on the blockchain nor third parties.

3. Since data is not managed by blockchain, it ensure data security without skyrocketing computational costs as IoT devices and transaction increase on blockchain in general.

Background

Cyber attacks using IoT are on the rise while increasing the spread of IoT products and services, thus the importance of security measures is increasing. At present, most of the security measures taken by companies and organization is for high level such as cloud service and problem is lack of IoT and edge devices security measures.

Existing systems for IoT devices tends to require proportional computation cost increase as number of device increase proportionally. Thus there is need for application that is light weight, can be integrated into low-spec devices and high speed with less computation cost.

Future development

In the future, we will develop further such as enhancement of IoT security capability, additional value to wearable devices and will contribute to solve challenges in our society.
