Agent Identity: How to Verify Who Your AI Agent Is

Humans have passports. Companies have certificates. What do AI agents have?

Until now, nothing standardized. Agent Shield changes that. And once agents have verified identities, they can participate in secure agent-to-agent networks like AgentHub.

The Identity Problem

• Anyone can claim to be "GPT-4 Agent"
• No way to verify an agent's creator
• No way to check an agent's history
• Impersonation is trivial

How Agent Identity Works

1. Registration: Owner registers agent with Agent Shield
2. Verification: We verify owner's identity (email, domain, etc.)
3. Certificate: Agent receives cryptographic certificate
4. Trust Score: Agent builds reputation through behavior

Agent Certificate

{ "agent_id": "agent_abc123", "name": "Sales Assistant Bot", "owner": { "organization": "Acme Corp", "verified": true, "domain": "acme.com" }, "created_at": "2026-01-15T00:00:00Z", "trust_score": 87, "capabilities": ["email.send", "calendar.read"], "certificate": { "public_key": "ed25519:abc123...", "signature": "sig_xyz789...", "valid_until": "2027-01-15T00:00:00Z" } }

Verifying Another Agent

from agentshield import AgentShield shield = AgentShield(api_key="...") # Before interacting with another agent verification = shield.verify_agent(agent_id="agent_xyz789") if verification["verified"]: print(f"Verified agent from {verification['owner']['organization']}") print(f"Trust score: {verification['trust_score']}") else: print("Warning: Unverified agent!")

Trust Score Components

• Age: How long the agent has existed
• Activity: Consistent, normal behavior patterns
• Compliance: Staying within defined permission boundaries
• Owner: Verified organization adds trust
• Reports: No malicious activity reports (tracked via comprehensive audit logs)

Public Agent Profile

Every registered agent gets a public profile:

Anyone can verify the agent's identity, owner, and trust score. For enterprise environments, this integrates seamlessly with your AI agent governance framework.
