Authentication Architecture

TrusCodes authentication architecture turns scanning into enforceable verification—by validating identity, enforcing lifecycle rules, and producing audit-ready evidence.

What this architecture solves

Verification, not visual checks

Most “authentication” fails because it only checks if a code looks valid, not whether it can be reused. TrusCodes verifies:

The four enforceable controls

All four, working together

01

Cryptographic proof

02

Physical tamper evidence

03

Backend lifecycle enforcement

04

Structured audit logging

Verification, not redirection.

End-to-end flow

Simple and defensible

  1. 01
    Identity generationA cryptographically generated identity is created for the label.
  2. 02
    Physical anchoringTamper-evident controls help prevent removal and reuse.
  3. 03
    Backend verificationThe backend validates authenticity and checks lifecycle policy.
  4. 04
    Lifecycle decisionThe system decides whether the identity is Valid (first-time), Consumed (single-use already used), Blocked (policy violation), or Flagged (suspicious pattern).
  5. 05
    Evidence creationThe result is stored as structured logs for governance review.
Two lifecycle models

Core design choice

Model A

Single-Use (Consumptive) Authentication

Used when the code represents a claim or entitlement that must not be transferable.

Model B

Persistent Identity with Lifecycle Control

Used when the identity must be scanned many times across legitimate events (traceability).

Audit-ready evidence

What buyers ask for

Typical evidence outputs include:

Frequently asked

FAQs

How does TrusCodes verification work?
It validates cryptographic identity in the backend, enforces lifecycle rules, and records structured audit logs so copied or reused codes fail and evidence is preserved.
Why isn’t cryptography alone enough?
Because a genuine code can still be copied and replayed unless the system enforces reuse rules and records misuse attempts.
