Overview#
The Evidence Retention Automation module enforces evidence retention policies automatically, applying the correct rules to each item, blocking disposal while legal holds are active, and routing expired material through governed, fully audited disposal and deletion workflows.
A law enforcement agency managing evidence from thousands of closed cases faces a practical challenge: some items must be retained for decades under statute, others for just a few years, and some must be destroyed on a specific schedule to comply with data protection obligations. Manually tracking every retention deadline across that volume is error-prone. Disposing of something too early creates legal liability. Retaining something past its required disposal date creates a different kind of liability. Neither outcome is acceptable.
Retention rules are applied to each evidence item based on case type, jurisdiction, offence category, and any active legal holds. When a retention period expires and no hold is in place, the system schedules the appropriate disposal workflow and generates an audit record of the decision. When a legal hold is applied, disposal is blocked regardless of the underlying policy until the hold is formally released. For digital evidence recordings, deletion is never a one-click destructive act: a deletion must be formally requested, is blocked while any legal hold applies, requires approval by a second person, and executes as a recoverable soft-delete with every step audited. Financial regulators, prosecutorial offices, coroner services, and criminal investigation units all use this module to manage retention compliance without relying on manual tracking.
Key Features#
- Automated retention enforcement based on configurable policies tied to case type, offence category, jurisdiction, and regulatory mandate
- Legal hold management that blocks disposal of any evidence under an active litigation or appeal hold, with hold status visible across all affected items
- Scheduled purging workflows triggered automatically when retention periods expire, with approval steps configurable by evidence sensitivity
- Compliance validation confirming that retention policies meet current regulatory mandates, with alerts when policy gaps are detected
- Real-time monitoring and reporting of retention policy compliance status across entire evidence collections
- Policy-driven lifecycle transitions from active through archive to disposal, applied consistently without manual scheduling
- Multi-jurisdiction retention rule support for organisations operating across different regulatory frameworks simultaneously
- Audit trails for all retention decisions, hold applications, hold releases, and disposal actions, meeting the documentation standards required for regulatory inspection
- Governed deletion lifecycle for digital evidence recordings, moving through formal request, legal hold check, and approval by a second person before execution, so separation of duties prevents any single actor from destroying evidence
- Recoverable soft-delete execution with no hard deletes: approved deletions remain reversible, and every lifecycle transition is written to the audit log
- Guided vendor connection onboarding for camera and video systems, with connections listed and created using credentials encrypted at rest, tested against the live vendor system, and used to discover offline assets
- Honest capability reporting when a connected vendor system cannot enumerate offline assets, so coverage gaps are surfaced rather than silently assumed
- Organisation-level isolation of all retention, deletion, and vendor connection operations
Use Cases#
- Enforcing automated retention policies across large evidence collections to maintain regulatory compliance without manual tracking
- Managing legal holds to prevent accidental disposal of evidence under active litigation, appeal, or regulatory investigation
- Scheduling and executing evidence purging workflows when retention periods expire, with appropriate approval chains for sensitive material
- Monitoring compliance status across all active retention policies and generating audit reports for regulatory inspection or internal review
- Processing end-of-retention footage through a defensible deletion workflow, where an evidence manager raises the request and a second approver authorises execution, producing a two-person approval trail
- Placing a legal hold as counsel that immediately freezes deletion of related recordings until the hold is lifted
- Onboarding a new vendor camera system connection with a live connection test and offline asset discovery before recordings enter retention management
Integration#
The Evidence Retention Automation module connects with evidence management, legal hold systems, compliance reporting, and storage management. Connections to vendor camera and video systems are onboarded through a guided flow: each connection is created with its credentials encrypted at rest, verified with a live test against the vendor system, and then used to discover offline assets so recordings can be brought under retention governance from the outset.
Open Standards#
- ISO 8601: All retention period boundaries, disposal dates, hold timestamps, and audit log entries are expressed as ISO 8601 date-time strings with UTC offsets, ensuring unambiguous chronological ordering across jurisdictions.
- RFC 3161 (Internet X.509 PKI Time-Stamp Protocol): Evidence export packages and audit records can be anchored to a trusted Timestamp Authority using RFC 3161 tokens, providing cryptographically verifiable proof of when a retention decision or disposal action occurred.
- ISO 19005 (PDF/A): Disposal audit records and evidence packs are exportable in ISO 19005-1 through ISO 19005-4 archival PDF variants, ensuring long-term readability without external dependencies for regulatory inspection files.
- W3C Verifiable Credentials Data Model v2.0: Chain-of-custody transfers and evidence provenance events are issued as signed W3C Verifiable Credentials, giving disposal and hold records a portable, cryptographically verifiable form.
- FIPS 180-4 (SHA-256 / SHA-512): Evidence integrity is verified at each lifecycle transition using SHA-256 as the primary digest and SHA-512 as a secondary check, so any tampering before or after a retention decision is detectable.
- OAuth 2.0 and JWT Bearer Token: Token-based authentication protects typed, auditable read and write workflows across the platform.
