Identity and Authorization for Humans and AI
PTERI protects people, AI agents, and existing enterprise systems with passwordless MFA, runtime authorization, and verifiable action evidence—without relying on shared secrets.
PTERI is developed using established cloud, security, and open infrastructure technologies.
ONE SECURITY LAYER
PTERI applies one verifiable authorization model across workforce access, AI-agent activity, and sensitive enterprise operations.
PTERI
Privacy Trust Engine
Identity, authorization, and evidence layer
Passwordless MFA
Verify people without reusable passwords or shared secrets.
Agent Authorization
Give every AI agent a verifiable identity and scoped authority.
Step-Up Approval
Require explicit approval before high-impact actions.
Action Evidence
Produce tamper-evident evidence of identity and authority.
MODERN SECURITY FOR EXISTING SYSTEMS
Critical data and workflows already live inside enterprise applications, databases, APIs, and infrastructure. PTERI adds passwordless access and action-level authorization without requiring those systems to be replaced.
Add passwordless MFA to existing applications, administrative portals, APIs, and workforce workflows.
Require stronger authorization when a person or agent attempts a high-risk operation.
Keep keys and authorization material outside prompts, agent memory, and exposed runtime components.
Integrate PTERI alongside existing identity providers, IAM platforms, applications, and security controls.
RUNTIME AUTHORIZATION FOR AI AGENTS
PTERI lets agents perform approved tasks without inheriting a user's full identity or possessing unrestricted credentials.
Give every agent a distinct identity that can be managed, verified, and revoked.
Define what the agent may do, which resources it may access, and how long its authority remains valid.
Verify identity, scope, context, and policy before a consequential action is executed.
Connect every agent action to the person, organization, or workflow that authorized it.
ONE MODEL OF AUTHORITY
Establish a distinct verifiable identity for the person, agent, application, or device.
Confirm the identity without relying on reusable passwords or shared authentication secrets.
Define the permitted action, resource, purpose, policy, and expiration time.
Require additional approval when the requested action is sensitive or high impact.
Validate the authority at runtime and produce tamper-evident evidence of the action.
ONE PLATFORM. MULTIPLE SECURITY BOUNDARIES.
Add passwordless MFA for employees, administrators, contractors, and customers.
Require explicit approval for administrative changes, production access, deployments, and credential management.
Control which tools, APIs, data, and actions each agent may use.
Reverify identity and authority before information is viewed, exported, modified, or shared.
Require scoped authorization before purchases, payments, payouts, or transfers.
Preserve identity, delegation, policy, and accountability when agents work together.
BUILT FOR YOUR EXISTING STACK
PTERI works alongside existing identity providers, applications, APIs, AI agents, MCP servers, and cloud infrastructure. Start with one sensitive workflow and expand over time.
identity = pteri.identify(user_or_agent)
action = pteri.define_action(resource, purpose)
authority = pteri.get_delegated_authority(identity)
decision = pteri.evaluate_policy(identity, action, authority)
if decision.allowed:
evidence = pteri.verify(decision)
return execute(action, evidence)
else:
return deny(decision.reason)BEYOND LOGIN SECURITY
Security cannot end when a session begins. PTERI can verify authority again when a person or agent attempts a sensitive operation.
PTERI works alongside existing identity and access controls to add passwordless verification and action-level authorization.
VERIFIABLE BY DESIGN
PTERI combines customer-controlled credentials, cryptographic verification, and an independent trust architecture to create durable authorization evidence.
Customer-Controlled Credentials
Sensitive keys and credentials remain under the control of the user or organization.
Cryptographic Identity
Every identity — human or AI agent — is verified cryptographically, not with a shared secret.
Scoped Authorization
Authority is limited to a specific action, value, and time window rather than unrestricted access.
Runtime Policy Verification
Policy is evaluated at the moment an action is requested, not only at login.
Tamper-Evident Evidence
Approved actions produce cryptographic evidence that cannot be altered after the fact.
Independent Trust Architecture
Evidence can be anchored beyond a single vendor-controlled database for additional integrity and resilience.
PTERI currently uses Litecoin proof-of-work and privacy-enhancing technologies as components of its independent verification architecture.
CLEAR CONTROLS. CLEAR BOUNDARIES.
PTERI verifies identity, delegated authority, policy, and action evidence without taking control of customer credentials.
PTERI does not replace endpoint security, application security, IAM, secure model design, or human governance. It does not claim to protect a fully compromised endpoint, user-approved malware, or physical coercion.
PTERI connects people, AI agents, applications, and enterprise systems through passwordless authentication, scoped authorization, and verifiable action evidence.
AUTHORITY IN YOUR CONTROL
The PTERI App lets users authenticate, control credentials, review delegated authority, approve sensitive actions, and access supported payment and privacy capabilities.
Questions we get asked most about PTERI, security, and how it all works.
Start with one application, one agent, or one sensitive workflow. Add passwordless authentication and runtime authorization without replacing your existing infrastructure.
