Entering a New Era of Digital ID – DIDVC “MySov” Released
March 11, 2025
Tokyo, March 11, 2025 – Digital Platformer Inc. (Headquarters: Chiyoda-ku, Tokyo; CEO: Ikkei Matsuda) is pleased to announce the official release of MySov, a next-generation digital identity solution leveraging Decentralized Identifiers (DID) and Verifiable Credentials (VC). MySov builds upon SHIKI, a digital identity system implemented for banks and municipalities in 2024, significantly enhancing identity scalability, security, and interoperability.
By integrating Multi-Party Computation (MPC), blockchain, and biometric authentication, MySov delivers a robust decentralized security framework, offering individuals and enterprises a safer, more flexible approach to digital identity management.
As a foundational digital ID solution for the Web3 era, MySov also facilitates the formation of Decentralized Autonomous Organizations (DAOs) and supports NFT-based ownership verification, extending its utility across diverse use cases in finance, governance, and the digital economy.
Key Features of MySov™
1. Enhanced Scalability & Security: Evolution from SHIKI
MySov builds on SHIKI, which enabled My Number-based identity verification for banks and municipalities. With MySov, identity verification is now more flexible, scalable, and interoperable, offering:
・Beyond My Number: Identity authentication no longer reliant solely on My Number, ensuring broader usability.
・Verifiable Credentials (VCs): Multi-purpose identity credentials applicable across services.
・Advanced Security: Combining MPC, blockchain, and biometric authentication to enhance data protection and user sovereignty.
These innovations drive Self-Sovereign Identity (SSI) adoption, giving users full control over their digital identities.
2. Digital Identity for the Web3 Era
MySov integrates seamlessly with Web3 technologies, enabling new digital identity use cases in decentralized ecosystems:
・DAO Governance & Membership: Securely authenticate DAO members and verify voting rights.
・NFT-Based Ownership ID: Issue DIDs linked to NFT ownership, ensuring transparent transactions and verifiable ownership in gaming, metaverse environments, and digital art markets.
・DeFi-Compliant Secure Authentication: Provide trustworthy IDs for DeFi platforms, strengthening AML (Anti-Money Laundering) compliance.
By aligning identity verification with decentralized economic systems, MySov unlocks new possibilities for Web3 identity management.
3.Identity Gradient Management Based on Credential Importance
MySov enables gradient management based on the importance of the identity a user holds, providing the necessary level of authentication securely while ensuring identity flexibility.
MySov introduces hierarchical identity management, allowing users to assign different levels of authentication based on the nature of their credentials:
・Government-Issued Credentials (My Number, Driver’s License, Passport, etc.) → Secure access to municipal and financial services.
・Professional & Academic Certificates → Credential validation for recruitment and industry-specific verification.
・Corporate ID & Access Badges → Seamless integration for employee verification and secure building access.
This flexible verification model ensures that each identity is tailored to its intended use case, enhancing both security and convenience.
4. Seamless User Experience with Decentralized Single Sign-On (SSO)
Unlike traditional identity systems requiring separate credentials for each service, MySov enables decentralized SSO, allowing users to access multiple platforms with a single ID. This eliminates password fatigue and reduces authentication friction, enhancing both security and usability.
CEO’s Statement
— Ikkei Matsuda, CEO, Digital Platformer Inc.
“The development and deployment of SHIKI gave us deep insights into the challenges of traditional identity management. While My Number-based verification remains critical for government and financial institutions, the future of digital identity requires scalability, enhanced security, and broader interoperability. With MySov, we have expanded SHIKI’s capabilities to support Web3, DAOs, NFTs, and next-generation identity solutions. This will enable new levels of trust and efficiency in *finance, government services, and digital economies worldwide.”
Use Cases
1. For municipalities: Digitization of official certificates
By registering My Number or a driver’s license as a Verifiable Credential (VC), citizens can digitally authenticate for government services, eliminating reliance on paper-based records while enhancing both efficiency and security.
2. Strengthen KYC for e-money services
As digital payments and e-money platforms continue to expand, fraud prevention and identity verification remain critical challenges. MySov integrates DID-based KYC into e-money services such as “〇〇Pay”, enabling:
・Faster identity verification for users.
・Reduced fraud risk and operational costs for service providers.
・Improved regulatory compliance through continuous identity authentication.
can be realized.
3. Secure authentication for DeFi
MySov strengthens AML compliance in DeFi platforms, ensuring that only verified users can participate in financial transactions, mitigating illicit activities.
4. Recruitment and credentials: Realization of digital resumes
Applicants can store academic degrees and certifications as Verifiable Credentials, enabling instant and trustworthy verification by employers. This streamlines the hiring process while reducing credential fraud.
5. For companies: Integrated management of employee IDs and entrance passes, security clearance management
MySov facilitates enterprise authentication, allowing corporate ID, employee badges, and facility access credentials to be seamlessly managed within a single digital identity. Additionally, MySov enhances security clearance management, streamlining the authorization process and ensuring efficient, controlled access across various security levels.
6. Identity management for DAOs (Distributed Autonomous Organizations)
・Secure DAO membership authentication using DID technology.
・Transparent and verifiable voting rights for decentralized governance.
7. Issuance of ownership ID and identification using NFT
・Assigning DIDs to NFT owners, ensuring authentic ownership verification.
・Enhancing security in gaming, metaverse, and digital art transactions by linking NFT ownership to verified identities.
・DAO and DeFi integration: NFT-based exclusive access rights and incentives.
This innovation eliminates identity fraud within NFT marketplaces and decentralized finance ecosystems, reinforcing trust and security.
Future Roadmap
Looking ahead, MySov will continue advancing decentralized security by integrating:
Additionally, MySov will expand its applicability across Web3, DAOs, NFTs, and DeFi, setting the foundation for a fully decentralized and interoperable digital identity framework.
With MySov, we are working towards a trustless identity network where a single, verifiable ID can securely unlock access to diverse services.
