Authyr for Evidence · Law Enforcement
Chain of custody that
survives the courtroom.
Every time evidence is collected, transferred, accessed, or analyzed, Authyr issues a cryptographically signed receipt — sealed by mathematics, not policy. Alter any record, even years later, and the chain visibly breaks. Tampering stops being something the defense argues about. It becomes something the math detects.
The problem
Every custody gap is a defense opening.
Paper logs prove someone wrote something down — not that nothing changed afterward.
Database records can be edited by anyone with admin access, and juries are learning to ask who could have.
Digital evidence multiplies — bodycam, phone extractions, photos — and copies travel faster than their hashes get recorded.
The cost lands as suppression motions, lost cases, civil settlements over evidence handling, and overtime spent reconstructing who touched what.
What it's worth
Helping in three directions at once.
Cases stick
Suppression motions die against a chain the defense can verify themselves. Pleas come faster when the other side checks the math and stops betting on a custody challenge. Convictions survive appeal.
Lawsuits shrink
Civil claims over evidence handling — and the settlements that follow — collapse when custody is provable instead of arguable. One avoided settlement pays for this many times over.
Hours come back
No more weekend reconstructions of who handled what before trial. The signed chain is the testimony prep.
Why it survives trial
The defense can verify it too. That's the point.
Authyr is a neutral third party, and verification runs on published mathematics. The DA, the defense, the judge, and an appellate court five years from now all check the same chain and get the same answer — without trusting the department, the lab, or Authyr. Evidence your opponent can independently verify is evidence that stops being the argument.
An integrity layer — not another system to migrate to.
Your evidence room, RMS, and bodycam platform keep working exactly as they do now. Authyr sits alongside: each custody event gets a signed receipt in seconds, and a court-ready packet on demand. No PII required — records reference case and item numbers, never people.
Not a concept
The chain is live today.
The signed-receipt infrastructure is in production now. Open the interactive demo, edit any record with your own hand, and watch the cryptographic chain break in front of you — the same verification any defense expert could run.
