Trust (digital identity, etc.)

Last Updated:

As a foundation for data distribution and coordination, there is a need for mechanisms and tools that help trust the parties with whom data is exchanged as well as the data, and that improve the possibility of verifying the identity and existence of the subject and the non-tampering and authenticity of the data. Currently, we are promoting initiatives that utilize digital identities of "people, corporations, things, etc." to establish and prove "identity, qualification, attributes, etc." in the digital realm.

Notice

Outline

Through various policies to secure and improve trust, we aim to promote digital completion of administrative procedures, utilize digital identities across countries, and improve users' peace of mind and safety regarding the handling of personal information. Specifically, we are working on governance and use cases related to the use of digital identities, as well as promoting international cooperation.

Efforts to expand digital identity

The use of digital identity, which establishes and certifies the "identities, qualifications, attributes, etc." of "persons, corporations, things, etc." in digital media, is a fundamental and important element for ensuring and improving trust in the digital society.
We are considering and implementing measures to expand the social implementation and appropriate and effective use of digital identities, as well as measures related to governance so that people can use them with peace of mind.

Expert Panel on Summarizing Issues of Attribute Verification

In order to realize digital certification of "identity, qualification, attribute, etc." (collectively referred to as attribute certification), which is necessary for the digital completion and automation of administrative procedures, etc., we will discuss expected risks in the utilization of VC and DIW, which are new related technologies and mechanisms, appropriate technical and operational measures against each risk, and methods to promote their implementation.

Verifiable Credential(VC/VDC)

Verifiable (Digital) Credential (VC/VDC) is a general-purpose machine-readable data format and data distribution format for information on "identities, qualifications, attributes, etc." of "persons, corporations, things, etc." This VC is attracting attention as an important trend related to digital identity. Regarding VC, we will consider the governance required for appropriate utilization, such as organizing the benefits and points to note. function

Expert Panel on Governance in Leveraging Verifiable Credentials (VC/VDC)

Based on the relationship with the current laws and regulations, systems, and mechanisms, we will organize the points to note regarding the process of using the VC. In addition, we will consider necessary governance and discuss the use of the VC that is expected to be utilized in the future.

Digital Identity Wallet(DIW)

The "Digital Identity Wallet," a mechanism and app (wallet) that allows individuals and corporations to store, manage, and present their "identity, qualifications, attributes, etc." information by themselves, is expected to contribute to improving privacy and completing procedures digitally. We are implementing measures such as social implementation and governance so that citizens can use and utilize it with peace of mind.

Digital Identity Wallet (DIW) Advisory Board

An advisory board of external experts was held to examine and organize the benefits, risks, and points of contention as a reference and premise for considering measures for the future social implementation of DIW.

Efforts toward International Collaboration and Interoperability

In recent years, international discussions on governance and interoperability of digital identities have become active. Under this initiative, we are participating in international discussions and demonstrating use cases to ensure interoperability between Japan and other countries and regions. For details, please refer to the following page.

Based on the Japan-EU Memorandum of Cooperation on Digital Identity, we implemented a pilot project on digital identity. The purpose of this project is to show that certificates related to digital identity can be interoperable even between different countries and regions. We conducted a demonstration of VC communication via DIW based on a specific use case, and confirmed its effectiveness. As a result, we found that by utilizing existing frameworks, the inter-operability of digital certificates can be realized even in countries and regions with different governance structures, as well as in environments with different technical regions. As the results of this project, we compiled a report jointly with the EU on the background, purpose, contents of implementation, and knowledge obtained, including technical aspects. Architecture

We also compiled a demonstration results report and a demonstration scope definition document that describe the technical aspects of this project in more detail.

Other Efforts

We are also making various other efforts to secure and expand trust in digital.

Digital Society Promotion Standard Guidelines for Trust

Digital Society Promotion Standards Guidelines Among , we are formulating and operating guidelines related to securing and expanding trust and appropriate use of digital identities. For details, please refer to the following page of the Digital Society Promotion Standards Guidelines.

Trusted Web

The Trusted Web is an initiative that adds a new framework of trust to the Internet and the web. It is a mechanism that strengthens the control of data by individuals and corporations without relying on a specific service, and a mechanism that allows the verification of exchanged data and the other party. I prepared a white paper summarizing that idea, and I worked on various fields using that idea.
