In recent years, the risk of personal information leaks due to unauthorized access or cyber attacks has been increasing. In response to this situation, the Personal Information Protection Act requires that when a personal data leak occurs and there is a risk of harming an individual’s rights and interests, a report must be made to the Personal Information Protection Commission and notification must be given to the individual.<\/p>

However, currently, even if you only want to confirm a person’s name, you must present a driver’s license or other identification document, resulting in the disclosure of unnecessary personal information. There are attempts to limit the scope of disclosure, such as by submitting copies of identification documents with blacked-out parts, but this creates other problems, such as the hassle of blacking out parts and making it difficult to verify their authenticity.<\/p>

To solve this problem, Daiwa Institute of Research and Recept aim to provide a “self-sovereign digital certificate service.” With this service, information from identity verification documents is digitized and stored on the user’s smartphone, and the user can select and submit only the minimum amount of identity verification information that needs to be disclosed. In addition, blockchain technology allows information handlers to verify the authenticity of the information they receive. This reduces the workload associated with limiting the scope of personal information disclosure while ensuring authenticity, satisfying the needs of both those who provide and those who handle personal information.<\/p>

As the core company of the Daiwa Securities Group’s digital strategy, Daiwa Institute of Research has been providing high-quality and highly reliable services, including core systems for securities operations, and promoting business model transformation using cutting-edge technologies such as blockchain and AI.<\/p>

Recept is a startup specializing in DID*1\/VC*2 technology with the mission of “Becoming a company that changes history.” Its flagship product, “proovy,” is an integrated platform that enables the issuance, verification, and management of digital certificates through wallets. Since its service release in March 2024, it has been adopted primarily by educational institutions and certification issuing organizations, and has become the second company in Asia to obtain EBSI (European Blockchain Services Infrastructure*3) international certification.<\/p>

Now, by combining the secure system development technology and blockchain technology that Daiwa Institute of Research has cultivated in the financial industry with Recept’s knowledge and services in the DID\/VC field, the two companies have decided to promote the development of a “self-sovereign digital certificate service.”<\/p>

  1. DID (Decentralized Identifier) ​​is an identifier for realizing decentralized digital ID. Digital ID allows users to safely and independently manage their own identity in the digital space. Relevant credentials are stored in a digital wallet that the user manages, allowing selective disclosure of information. User-centric decentralized management is expected to improve the interoperability of digital IDs across organizations and borders, realizing a more flexible and secure digital identity ecosystem.<\/li>\n
