HiLocker

Perception-aware protection for sensitive information displayed, opened, queried, inspected or consumed.

Executive summary

HiLocker addresses perception & human interface security through evidence-backed security workflows and auditable operations.

Core capabilities

• Perception-aware protection
• Interface masking and reveal
• Application/database presentation controls
• Document/message/log protection
• Policy-driven audit

Operational model

The architecture separates presentation, application services, protected configuration and evidence/data storage. Integrations provide authoritative production telemetry.

Security principles

• Least privilege
• Server-side secret handling
• TLS-protected interfaces
• Auditable actions and evidence
• Separation of management and protected data

Deployment

A hardened Ubuntu management server can operate behind Nginx with systemd-managed services, centralized identity, backup, monitoring and controlled integration endpoints.

Architecture considerations

A production evaluation should examine data sources, trust boundaries, identity, APIs, storage, administrative controls, evidence handling, reporting and failure modes.

Security review checklist

• Authentication and authorization
• Credential and secret storage
• Encryption and transport security
• Administrative auditability
• Integration trust boundaries
• Data retention and minimization
• Export and reporting controls
• Recovery assumptions

Evaluation success criteria

Success should be measured using workflow improvement, evidence quality, control effectiveness, usability, reporting value and integration reliability.
