Built for defensible custody
Six capabilities that turn evidence handling from a liability into an asset.
Immutable audit trail
Every custody event is sealed into a SHA-256 hash chain. Alter one record and the whole chain breaks — tampering becomes mathematically obvious.
AI missing-docket prediction
Bring your own OpenAI or Gemini key and let Zephyr flag evidence at risk of being lost, mishandled, or tampered with before it costs you a case.
QR & RFID tracking
Tag every item with a scannable QR or RFID reference and move it through your facility with a single scan from any phone.
Mobile evidence capture
Photograph and register evidence at the scene. Images are stored securely and bound to the item's custody record from second one.
Biometric verification
Gate sensitive actions like sealing or releasing evidence behind an on-device biometric check using your device's Face ID, Touch ID or Windows Hello.
Chain integrity checks
Verify the full custody chain of any item on demand and see instantly whether it is intact or exactly where it was broken.
Three steps to an unbroken chain
Register the evidence
Open a case, capture a photo, assign a QR or RFID tag. Zephyr writes the genesis block of the custody chain automatically.
Log every movement
Transfers, check-outs, analysis and seals are appended as new blocks — each cryptographically linked to the one before it.
Prove it held
At any point, verify the chain and run AI risk analysis to demonstrate an unbroken, defensible chain of custody in court.
