A platform for verifiable authority.

PTERI connects identity, scoped authorization, signing interfaces, and action evidence across human and automated workflows.

IDENTITY

Distinct actors

Represent users, AI agents, applications, and services as separate participants in the authorization flow.

AUTHORITY

Scoped permission

Connect approval to the action, value, resource, and time window required by the application.

EVIDENCE

Verifiable result

Produce an authentication or authorization result that the application can retain with its own operational records.

Product family

Platform, product, and interface.

PTERI Platform

The underlying identity, authorization, and supported trust infrastructure.

Pteri-Auth

The Google Cloud Marketplace commercial product for authentication and authorization workflows.

PTERI Wallet

The customer-controlled signing experience across Android, iOS, and supported browsers.

Deployment approach

Integrate at the boundary.

PTERI is designed to work with existing applications, APIs, and identity controls. Begin with one login, approval, agent action, or service workflow and expand after measuring the result.

One control plane

Built for agentic, robotic, and human operations.

PTERI extends identity from “who logged in?” to “which actor was allowed to perform this exact action, under whose authority, and for how long?”

01 / People

Fresh human approval

Use a device-bound cryptographic key—optionally unlocked by a device-native biometric—to approve sensitive actions without sending a face or fingerprint template to the service.

02 / AI agents

Scoped machine authority

Give each agent its own identity, tools, limits, expiry, and revocation path. Keep authority outside prompts and model memory.

03 / Robots and devices

Signed physical operations

Bind commands to a known device or robotic identity and require policy-compliant authorization before a consequential physical action.

04 / Legacy systems

Protect without a rewrite

Place a cryptographic approval boundary in front of existing portals, APIs, administrative tools, and high-risk workflows.

Identify the actor→Bind the request→Verify policy→Record evidence

Biometric + cryptographic

The biometric can unlock the key. The signed proof authorizes the action.

Where the device and platform support it, a native biometric can unlock a locally held cryptographic authenticator. The service verifies the resulting signed proof; it does not need the biometric template itself.

Design principle informed by NIST guidance on phishing-resistant authentication ↗. Deployment details depend on the selected authenticator and architecture.
