The custody model

Five stages, each independently verifiable and cryptographically sealed

  1. 01

    Capture

    Fingerprint at the edge

    The moment a camera writes a segment, an SHA-256 digest is computed at the edge appliance and stored separately from the video bytes.

  2. 02

    Preserve

    Object Lock, compliance mode

    Originals are written once and locked. Not even a Wisp administrator can alter or delete them before the retention window closes.

  3. 03

    Compress

    Working copy only

    Encoding to HEVC produces a separate working copy. The original stays untouched; the transform itself is logged and signed.

  4. 04

    Track

    Signed, append-only ledger

    Every access, transform, tier move, and export is timestamped and cryptographically signed into a tamper-evident ledger.

  5. 05

    Retrieve

    Court-ready restore

    When counsel needs it, the full-fidelity original is restored with a complete, verifiable custody trail attached.
