Summary of the actual session: Identity in the AI ​​Metaverse era Discussion notes

Overview

• Event name: Part of the Digital Space Conference 2025
• Date and Time: January 2025, 2
• Place: Tokyo Midtown (on-site) and YouTube live streaming
• Performer:
  • Virtual Beautiful Girl Nemu (Metaverse resident, VR content creator)
  • Natsuhiko Sakimura (Chairman of the OpenID Foundation)
• ThemeIdentity in the age of the AI ​​metaverse

Main points

1. Current status and potential of the metaverse

• Description of the Metaverse Environment:
  • Immersive experience using VR goggles and face trackers
  • Capable of performing actions beyond physical limitations (size change, gravity nullification, etc.)
  • A real study environment can be created in VR, allowing various activities to be carried out there.
  • The emergence of low-cost headsets such as Meta Quest 3s has accelerated their popularity
  • It is often compared to a world where magic can be used (teleportation, creation of objects, etc.)
• The technical advantages of VR:
  • Optically, you are looking at something far away, so your eyes will not get tired easily.
  • Creativity beyond physical constraints
  • You can use multiple avatars to express yourself in different ways
• Japan's VR population:
  • Almost doubled in the past year
  • The growth rate of Japanese users is high even when viewed globally

2. Digital Identity and Multiple Personalities

• Types of avatars and reasons for choosing them:
  • Humanoid avatars are chosen by people who want a more immersive experience that is closer to reality
  • Fantasy genre is chosen by people who seek characteristics that cannot be expressed in reality.
  • As time goes on, the number of human-like avatars is decreasing and the number of diverse avatars is increasing
• Dual Identity:
  • Approximately 57% of users intentionally separate their virtual identity from their real self
  • Reason for separation: To avoid prejudice, to distinguish between reality and fiction
  • Reason for publishing: Expanding network, seeking real and virtual connections
• The concept of "bunjin economy":
  • An economic structure in which one person acts with multiple personalities and identities
    • Incidentally, ISO/IEC 2011-24760, published in 1, already defines identity and partial identity as synonyms, stating that people use different identities for different contexts.
  • Currently, about 13% consider their identity in VR to be their main identity, and 27% hope to make it their main identity in VR in the future.
  • Self-expression and psychological effects of identity switching

3. Digital Identity and Privacy Challenges

• The role of IdP (Identity Provider):
  • Standardization of online authentication (OpenID Connect, etc.)
  • Context-specific identity management
  • The principle of "don't mix": Different identities should be kept separate
• Current Institutional Challenges:
  • Difficulty in conducting economic activities using a virtual identity (tax returns, financial transactions, etc.)
  • Balancing privacy protection and identity verification
  • The problem is the imposition of a holistic identity
  • The ideal is to "use different identities according to the relationship with each context"
• Direction of the solution:
  • A mechanism to minimize the information visible to stakeholders
  • A system in which business identifiers are handed over to the National Tax Agency and converted into tax identities (identifiers are My Numbers) for processing
  • Possibility of automatic processing using personal AI

4. Japan's Potential and Future Outlook

• Japan's Advantages:
  • Low barriers to creative activities (doujin culture, etc.)
  • High receptivity to VTuber culture and metaverse activities
  • High visibility of virtual presence in the media
• Future prospects:
  • Social implementation of technically feasible mechanisms
  • The need to influence the legislature and administration: the voices of voters are needed to do so
  • New forms of social participation in an ageing society
  • New economic development through a fundamental overhaul of the ID system

Conclusion

Multiple identities (divisions) in the metaverse are already technically possible, but implementation and legal development are needed to link it to economic activities and social systems. Japan has a high affinity with VR culture and has the potential to take a leadership role in this field. The challenge for the future will be to create an environment in which people can "live more true to themselves" through the metaverse.
