November 26, 2018



■ Achieving highly transparent and reliable data distribution through the linkage of the Personal Data Store (PDS)*1 and block chain technology*2
■ Verifying the safety, etc. of data distribution by utilizing smart contract*3, which connects consumers with companies/organizations for information sharing
■ Collaboratively developing an advanced encryption key technology and building a platform that enables ID management and data linkage (patent pending)

TOPPAN FORMS CO., LTD. (headquarters: Minato-ku, Tokyo; President: Koichi Sakata; hereinafter “TOPPAN FORMS”) and ZEROBILLBANK JAPAN Inc. (headquarters: Chiyoda-ku, Tokyo; President: Junichi Horiguchi; hereinafter “ZBB”) will collaboratively develop a service that links the data distribution platform of TOPPAN FORMS with the block chain and smart contract technologies of ZBB. In future, both companies will verify the safety and viability of data distribution through demonstration tests, etc., aiming to provide a new information linkage service among companies.


TOPPAN FORMS builds the Personal Data Store (PDS), which stores and manages personal data*4 in a high security environment, and other data distribution platforms.
ZBB develops and provides ZBB CORE, a platform that allows the block chain and the smart contract to be used as APIs. It aims to build a next-generation token economy*5, which efficiently collects a large quantity of data by linking existing systems and services and allows the secure sharing, replacement, and utilization of the data among multiple companies.
By linking the service infrastructure provided by both companies, personal data and confidential data can be stored and managed in a high security environment while securing the convenience of the block chain; that is, efficient information sharing. With this system that utilizes the smart contract, which contributes to the streamlining and automation of the procedures for contracts that were complicated in the past, we will support the creation of new markets and open innovations of companies.


In recent years, a variety of personal data such as daily life logs and healthcare data have been created along with the penetration of IoT devices. In Japan, the data distribution environment including a legal system has been organized, and the market for data distribution has been created and is expanding. On the other hand, personal data distribution on a block chain had an issue in terms of its handling though encryption. In this data distribution, by linking personal data managed by using PDS with block chain technology, transparency and reliability are secured and a system that is extremely convenient for companies and organizations is created, which enables us to expect new service creation, etc.

Future plans

Both companies will verify the safety, etc. of data distribution through demonstration tests with the aim of realizing a new information linkage service between companies.
