Medicolegal Evidence Chain

Anchor every result.
Defend it in court.

Bind each lab result to the analyst who signed it and to an immutable custody trail on a private medicolegal evidence chain. When an insurer or opposing counsel alleges tampering, the record answers with cryptographic proof instead of a disputed paper file.

The Foundation

The Execution Mechanics

Turn a contestable paper report into a signed, tamper-evident exhibit ready for litigation.

01.

Result Anchoring

The Evidence Chain module hashes each finalized result and seals it to the sample and the run, so any later edit to a value breaks the digest and is detectable.

02.

Analyst Attestation

The signing analyst binds a verified credential to the result at release, turning an anonymous printout into an accountable, individually attributed statement.

03.

Immutable Custody Trail

The Provenance Notary records every handoff of the specimen from collection to disposal, so no gap in possession can be alleged without evidence.

04.

Credentialed Identities

The DID and VC Ledger issues verifiable identities to collectors, analysts, and reviewers, so every action on a sample is tied to a known, credentialed party.

05.

Selective Disclosure

A court or insurer receives a verifiable extract proving integrity and custody for one case, without exposing the wider laboratory information system.

06.

Dispute Resolution

A tampering allegation is tested against the anchored hash and custody log in a single query, settling in hours what once took months of discovery.

The Evidence Lifecycle

Follow one specimen from collection through analyst release to a contested claim resolved on cryptographic proof.

Smart Contract Anatomy

Cerulea decomposes medicolegal integrity into modular contracts. Each layer registers, seals, attributes, and verifies a result without any single laboratory controlling the record.

Applicability Across the Spectrum

Tamper-evident result integrity is a horizontal capability. Here is how different actors in the medicolegal chain put it to work.

Diagnostic Laboratories

Release results that carry their own proof of integrity and authorship, so a lab defends its findings against tampering claims from a signed record rather than an internal audit that outsiders cannot trust.

  3. 3Dispute Records

Courts & Regulators

Receive a verifiable case extract that proves both the value and its chain of custody, replacing contested paper exhibits and expert testimony about handling with a single on-chain verification.

Network & Execution Architecture

Whether you are bridging a legacy laboratory information system or capturing collector attestations from the field, Cerulea routes both into one evidentiary record.

Track A: Laboratory System Bridging

For accredited labs on legacy LIS platforms. Finalized results are hashed and sealed as on-chain evidence through the API gateway without changing the analyst's workflow.

Track B: Field Custody Capture

For collectors and couriers on mobile. A signed app records each collection and handoff from a device wallet and routes it directly to the evidence chain.

Technical Methodology

The legacy timeline reflects regulated laboratory integration benchmarks. Wiring the LIS, building result-sealing and attestation logic, and shipping a court-facing verification portal for an average deployment takes a baseline of 8 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your custody and attestation rules into pre-audited WebAssembly binaries and provisions the private evidence ledger and verifier instantly.
