This page shows the "Trust ecosystem across mutual aid mutual aid services" exploried and tested by Dai Nippon Printing Co.,Ltd., in the 2023 "Use Case Demonstration Project of the Trusted Web".

Current issues and What Trusted Web Solves

Current Issues (Pain Points)

1. While trust verification is important for mutual aid applications to avoid problems, there are issues such as compatibility with privacy and increased hassle of registering user information.
2. Apps are offering supporter’s user profile and linking with SNS to enhance their trust. However, the system cannot prove the authenticity of such self-reporting data.
3. User rating can be used for trust verification. However, as some mutual help apps have small number of users, such app alone cannot provide sufficient rating data.

  
Mutual help achievement data is not accumulated→Unable to verify trust within mutual help app→Users cannot use app with confidence→does not increase users. Such a vicious circle can lead to withdrawal from the business.

 

What Trusted Web Will Solve

1. Users can manage their own data and provide it to the third party while protecting their privacy. Through this the scope of trust verification may be enhanced than ever.
2. Allows users to present their own data to third parties, potentially increasing the scope of trust validation without significantly increasing the need for privacy-conscious information entry.
3. By linking information across more than 300 sharing services, including mutual aid applications, mutual aid achievements from other applications can be accumulated and used for trust verification. In addition, by making the system capable of verifying mutual aid achievements in university entrance examinations and job searches, it will lead to stronger incentives for mutual aid app supporters.

 
Building an ecosystem with centralized database that links relevant information from all mutual help apps is not feasible. We studied method for sharing the mutual help achievement data by using distributed ID system technology as Verifiable Credential（VC）

Data to be verified

To issue a digital certificate of the activity results in the Mutual Aid App and to improve the trust of the supporter, the authenticity of the results is verified by the signature verification of the VC. The VC of a supporter issued by Mutual Aid App A is verified by another Mutual Aid App B according to the use case.

• 【Use Case 1】 Trusted Profile

The scope of trust verification for online profiles can be expanded by linking digital certificates whose issuers are trusted.

• 【Use Case 2】 Incentives from beverage manufacturers

Easy coordination of mutual aid performance to third-party firms can increase incentive creation opportunities and stakeholders.

• 【Use Case 3】 Nursery School Application Use Case

The program will be used to add points to the adjustment index for preschool applications, thereby providing incentives for community activities and streamlining the online application process.
 
 

Development of governance and community activities

• A trust framework was developed that could be agreed upon among multiple stakeholders, with reference to prior accreditation systems.

Business validation (including UX/UI)

• We discussed with the mutual aid application vendor how to display and link mutual aid achievements, including the creation of a demo screen for Wallet, which accumulates mutual aid achievements, and examined ways to promote the benefits through a more intuitive user experience.

Main Achievements

Governance Formulation

• The necessary items for the trust framework were organized and a document for the Mutual Aid Trust Framework was developed.
• Discussions were held with experts based on the formulated document, and responsibility breakdown points for each stakeholder were organized.

Business validation (including UX/UI)

• Examined customer experience use cases that would improve the trust scope by leveraging mutual aid achievements.
• Created mockups of the examined use cases and conducted UI/UX research through user interviews.
