NTT Docomo Business Has created a prototype registry system to establish the identity and credibility of autonomous digital agents involved in a virtual transaction or service. The project is indicative of increasing anxieties within the computing industry on autonomous agents performing business processes by establishing trust between agents.
The company said the new “AI Agent Attribute Information Registry” prototype is intended to support emerging AI-agent ecosystems where multiple autonomous software agents independently communicate, exchange data, and execute tasks using frameworks such as the Agent2Agent (A2A) protocol.
The registry system uses verifiable credentials (VCs) and digital certificates to authenticate AI agents and validate attributes such as ownership, operating authority, execution permissions, operational environment, and data usage policies.

AI Agents Create New Trust and Security Challenges
This development comes at a time when AI agents are quickly transforming from chatbots into fully autonomous digital workers who are able to make transactions, interact with enterprise systems and work with other AI systems without direct human oversight. An emerging consensus among industry insiders is that this “multi-agent” model of autonomous coordination among many AI agents may eventually become a core layer of our enterprise software and digital commerce ecosystem.
Even so, multi-agent systems pose some serious security and governance issues.
One of the biggest concerns is identity verification. Unlike human users or traditional enterprise systems, AI agents can be temporary, autonomous, distributed across platforms, and capable of acting independently at machine speed. Existing identity and access management systems were not originally designed for such environments.
NTT’s registry project aims to address this problem by creating a trust framework capable of verifying whether an AI agent is legitimate, who operates it, what permissions it has, and whether its credentials have been tampered with.
Building a Trust Layer for the AI Agent Economy
The initiative highlights the emergence of what industry analysts increasingly describe as an “AI agent economy,” where autonomous AI systems interact directly with businesses, platforms, and other AI agents to complete complex workflows.
NTT’s prototype registry uses “AgentCards,” digital identity profiles linked to verifiable credentials that authenticate the issuing organization and operational permissions of AI agents. The company said the system can help detect impersonation attempts, unauthorized modifications, and fraudulent agents operating within digital ecosystems.
In the future, the registry will be with digital ID wallets and distributed key-management system for heightened security and interoperability throughout organizations and worlds. With the growing technology industry more widely investigating use cases that rely upon decentralized identifiers (DIDs), cryptographic signatures and agent-based authentication regimes.
It has been further contended by some within the academy that existing identity systems used by humans may not be suitable for interacting with autonomous AI agents and entirely new identity systems may be needed.
Implications for Japan’s Technology Industry
For Japan’s technology sector, NTT’s project could become an important foundation for secure enterprise AI adoption.
Japanese enterprise and government organizations are ramping up their spending on generative AI, AI agents, automation platforms and digital transformation systems. As autonomous AI systems are rolled out across finance manufacturing logistics, telecoms and public sector services, so trust in AI identity infrastructure will (sooner rather than later) become an increasing concern.
The initiative by NTT’s registry makes Japan the early entrant into AI regulation, governance and digital trust infrastructure, which will grow increasingly strategic segments as global AI ecosystem matures.
This project also fits into Japan’s bigger picture endeavors around its cybersecurity policy, digital identity services and governance of AI setup. Japanese regulators and tech companies are now more and more intrigued by “trustworthy AI” to innovate without compromising security, accountability and regulation.
Enterprise Opportunities and Commercial Impact
The development would also offer enormous opportunities for companies involved in cybersecurity, digital identity management, cloud infrastructure and enterprise AI software.
Others have speculated that markets enabling the use of autonomous AI agents such as for commerce or business all require technologies for authentication, permission control, activity auditing, and regulatory monitoring.
This might mean increased speed of adoption for systems for online identity, cryptography, and AI governance. Sensitive transaction industries (banking healthcare government telco control systems, industrial machinery) will demand secure AI identity system as AI use expands.
The proliferation of AI-agent ecosystems may also lead to a revolution in enterprise software architecture. Rather than having to rely on human action, more companies will anticipate AI systems to autonomously negotiate workflow, invoke APIs, transact, and organize operational responsibilities. Secure authentication might be needed for such interactions to occur safely.
Global Competition Around AI Governance Intensifies
The announcement by NTT highlights additional concerns about increasing global competition over AI standards and governance setup. Around the world firms academics, and policymakers are debating how AI agents should be validated, governed, and audited.
As stakeholder concerns shift away from asking whether models perform toward asking how accountability, auditability, and operational reliability is maintained, policymakers are pivoting to an increased focus on it.
Over the past few years, scientists and entrepreneurs have pointed out that there is an absence of established architectures to be applied for the authentication and governance of AI-agents. Researchers and business people observe that in the absence of a trusted identity system, autonomous ecosystems where artificial intelligence agents operate could suffer from threats including impersonation integrity access issues, frauds and non-compliances.
Communities and discussions on other camps such as cybersecurity and AI are also demonstrating an increase in concern, for the issue of how entities will deal with permissions, audit and accountability of large-scale autonomous agents.
The Road Ahead
NTT’s AI agent identity registry project highlights how the next phase of artificial intelligence development is increasingly focused on trust, governance, and interoperability rather than only model capability.
As AI agents become independent participants in digital economies, organizations and governments will need solutions to ensure that they can verify the identities of those participating in digital environments.
In Japan’s technology sector, the project can enhance Japan’s competitive edge in areas such as secure AI infrastructure, digital identity, and enterprise AI management.
If successful, projects like NTT’s registry may eventually become foundational infrastructure for the emerging AI-agent economy, enabling autonomous AI systems to operate securely across industries, organizations, and international markets.
