Local key protection
Keys remain bound to the selected authenticator and are used to sign challenges.
Agentic + robotic + human
One authority model for every actor in the operation.
Modern work crosses people, autonomous agents, robotic systems, devices, services, and legacy software. PTERI is designed to preserve accountability across the full chain.
Human authorityIntent and accountability
Sets policy, delegates limits, and provides fresh approval for consequential actions.
signed delegation →
Agentic executionReasoning and orchestration
Plans work and invokes only the tools, data, and actions within its active scope.
verified command →
Robotic and device actionPhysical execution
Accepts commands from a verified authority chain and returns signed operational evidence.
protected interface →
Legacy operationsExisting systems
Continues running behind a modern approval boundary without an immediate full rewrite.
Power combination
Encrypted data. Cryptographic keys. Biometric convenience. Verifiable decisions.
No single control solves every risk. The strength comes from combining local authenticator protection, signed requests, policy, revocation, and clear evidence.
Biometric unlock
Where supported, device-native biometrics can unlock the local key without becoming the remote credential.
Runtime policy
Every request can be checked against actor, action, resource, scope, expiry, and delegation.
Action evidence
Signed decisions support operations, audit, incident response, and risk review.
Start narrow. Expand with proof.
