JCB and Mizuho to test digital identity interoperability with help from Fujitsu

By Staff Reporter

Fujitsu Limited, JCB Co., Ltd. and Mizuho Bank, Limited. has announced a joint demonstration trial aimed at further advancing a digital society in which digitally managed information attributable to individuals (i.e. ID information) can be safely and securely transacted online, distributed and linked between different industries, according to a report.

In the demonstration, JCB and Mizuho Bank will verify mechanisms to securely exchange and link participant ID information, such as names, addresses, and employers, on a cloud platform built by Fujitsu.

Approximately 100 Fujitsu Group employees in Japan will participate in the program, which is scheduled to last for approximately four months. Fujitsu has built a self-sovereign and decentralized digital identity exchange technology, which utilizes a blockchain solution from Fujitsu Laboratories.

Through this demonstration trial, Fujitsu, JCB and Mizuho Bank will confirm the accuracy of ID information held by multiple business operators and verify the mechanism by which customers can safely and securely control the distribution of ID information. Going forward, JCB, Mizuho Bank, and Fujitsu will consider innovative service models best suited to ID information management, regardless of the industry or sector.In recent years, much thought has been given to how individual data-which is acquired and managed by one service provider-can be utilized and distributed among other service providers to enable more convenient services. However, the importance of identity verification has been demonstrated many times over, as misappropriation of personal data, privacy risks, and damage caused by the unauthorized use of such data has become widespread. There is also a growing demand for business operators to be able to definitively prove the reliability of their business partners.

With the continued proliferation of digitization and circulation of personal ID information, it is essential to manage data with greater security and reliability, while also increasing the convenience of its shared usage.

JCB and Fujitsu have been conducting a joint research project on digital identity since 2019. From the viewpoint of improving the management and reliability of information held by multiple parties, we are conducting a demonstration trial on an interoperability model of identity information together with Mizuho Bank.
