Chain of custody that holds up to scrutiny.
Wrap native evidence formats in a signed envelope with cryptographic hashes, chain-of-custody events, and derivation lineage. Export court-readable verification reports without replacing the underlying evidence files.
- Native evidence preserved, not converted
- Signed chain-of-custody events
- Court-oriented verification reports
- Demonstrate authenticity and process integrity
- Track derivation across copies and conversions
- Keep original native evidence formats intact
- Produce reviewable reports for legal proceedings
Why justice & evidence teams need data-centric trust
Custody gaps
Reconstructing custody and transfers is error-prone and contestable.
Derivation tracking
Copies, conversions, and extractions lose their provenance.
Integrity doubt
Digital files are trivially altered without tamper-evidence.
OSDF solution architecture
Purpose-built capabilities layered on the open OSDF core and verification engine.
Evidence envelope
Preserve E01 images, video, photos, and reports with hashes.
Custody events
Signed transfer events link each custodian to a prior hash.
Private ledger
Detailed custody history under agency control with witnesses.
Court reports
Readable certifications for attorneys, courts, and opposing experts.
What you gain
- Demonstrate authenticity and process integrity
- Track derivation across copies and conversions
- Keep original native evidence formats intact
- Produce reviewable reports for legal proceedings
Designed for assessment
OSDF supports controls and evidence - a compliant deployment also depends on your environment, policies, and operations.
Evidence handling
Aligns with NIST guidance on hashing and chain-of-custody documentation.
CJIS-oriented
Designed to be assessed in the context of the full deployment environment.
Bring verifiable trust to justice & evidence
