Identity with boundaries.
Data with a purpose.
Define data, parties, retention and alternatives before enrolling a palm.
Which data moves where?
Choose a stage to inspect processing location, controls and lifecycle.
RGB / IR images
Capture within an authorized session.
- Input
- Person, purpose and fresh capture session.
- Processing location
- Device sensor by model; the profile determines edge or server processing.
- Controls
- Device identity, participant continuity, session expiry and approved transport.
- Output
- Capture data and session reference, not an identity decision.
- Lifecycle
- No default image retention; exceptions need an approved purpose and time limit.
- Exceptions and evidence
- Failed capture: retry or assistance. Record outcome/configuration without putting images in logs.
Quality and PAD
Check conditions before matching.
- Input
- Images and device context from the same session.
- Processing location
- Quality/PAD component under the approved version and profile.
- Controls
- Thresholds, assessed attacks, sensor and report scope.
- Output
- Accepted, retry or review required; not yet an identity verification.
- Lifecycle
- Minimal technical result; diagnostic data only under permitted exceptions.
- Exceptions and evidence
- Do not bypass PAD to increase success. Link reports to the actual model/version.
Feature extraction
From capture to a biometric representation.
- Input
- Capture accepted under the configured quality/PAD checks.
- Processing location
- At the edge or server named in the deployment profile.
- Controls
- Algorithm version, memory boundary and sensor compatibility.
- Output
- Features and configuration reference; not automatically anonymous data.
- Lifecycle
- Dispose of transient data, caches and crash artifacts under approved schedules.
- Exceptions and evidence
- Incompatible version: block use and reassess; retain version references rather than raw data.
Protected reference
Separate reference, identity and business record.
- Input
- Features, purpose, processing authority and binding version.
- Processing location
- A vault separated from identity and business-data stores.
- Controls
- Access control, key management and protection under the actual profile.
- Output
- A biometricRef governed by a binding to subjectRef.
- Lifecycle
- Revocation, re-enrollment and deletion are distinct; biology itself is not replaced.
- Exceptions and evidence
- Encryption does not prove irreversibility. Mechanism, access and evaluation records are required.
Purpose-bound matching
Verify 1:1 or identify in an authorized gallery.
- Input
- Fresh session, probe, authorized gallery/identity and purpose.
- Processing location
- Matcher within the declared processing boundary.
- Controls
- Thresholds, organization scope, revocation state and caller authority.
- Output
- An identity result, not an unrestricted authorization.
- Lifecycle
- Do not expand searches or reuse references beyond the authorized purpose.
- Exceptions and evidence
- Non-match or ambiguity: assist or step up; do not automatically merge records.
Decision and event
A contextual result for the relying application.
- Input
- Identity result, policy, resource and requested action.
- Processing location
- Decision layer and authorized business application.
- Controls
- Separate verification from authorization; check expiry, purpose and enforcement authority.
- Output
- identityResult, authorizationDecision, nextAction and evidenceRef under the contract.
- Lifecycle
- Retain minimal evidence under schedule; exclude images/templates from public logs.
- Exceptions and evidence
- A hash is not a signature. Trusted timestamping requires a confirmed TSA configuration.
Source identity, biometric references, business records and evidence have separate boundaries. Revocation and deletion remain controlled after each decision.

Deployment-specific responsibilities
| Area | Define before operation |
|---|---|
| Controller / processor | Determine from actual decisions about purposes and means, not from the product name. |
| Third parties | Disclose recipients and subprocessors where applicable; no confirmed list is supplied here. |
| Data transfers | Identify processing locations and cross-border requirements for the deployment. |
| Alternative access | Documents, cards, QR, VNeID or staff assistance as appropriate. |
