How it works
Authenticate, transfer, and verify — in three steps.
Authenticate
Create Authenticated Chain of Custody Forms to record any transaction of physical and digital evidence. Start from forms shaped by feedback from real investigators, labs, and counsel.
Transfer
Transfer custody to anyone in a verifiable 3-step process where both parties acknowledge the handoff — with proof stored in cryptographically secured, immutable records.
Verify
Any third party can verify a transaction without you sharing the underlying information. Our system stores only the hash values needed for authentication.
Why CustodyTrack?
Improve transparency and accountability, enhance data security and efficiency, and strengthen the integrity record behind your evidence — with reference to FRE 901, ISO/IEC 27037, and NIST SP 800-86 — all without having to develop your own blockchain or invest in expensive in-house computing resources.
Transparency & accountability
Every custody event is recorded in a clear, ordered timeline that both parties acknowledge.
Data security & efficiency
We store hash values and minimal metadata — not your evidence contents — so records are private by design.
Standards-based integrity
Records are designed with reference to recognized evidence and digital-forensics guidance — FRE 901, ISO/IEC 27037, and NIST SP 800-86 — so integrity is independently verifiable, without building your own infrastructure.
The tamper-evident seal
Think of it as a wax seal for digital records: if anything changes, the seal breaks and verification fails.
