Chain of custody software records who handled each piece of evidence, when, and what they did with it, then protects that record so it cannot be quietly changed. The goal is simple: when an item reaches a courtroom, you can prove it is the same item that was collected and that it has not been altered along the way. ROHOVOT builds that guarantee into the everyday workflow your investigators and paralegals already use.
What makes an evidence record tamper-evident?
- Append-only logging — entries can be added but never edited or deleted, so the history cannot be rewritten after the fact.
- Cryptographic hashing — each digital item is fingerprinted with SHA-256 at ingest, and re-hashing at any time proves it is byte-for-byte identical.
- Authenticated attribution — every action is tied to a named, logged-in user rather than a shared account, removing ambiguity about who did what.
- Time-stamped transfers — every handoff between custodians is captured with the date, time, and reason for the transfer.
How does hash verification protect digital evidence?
When you ingest a phone image, a hard-drive clone, or an exported chat thread, the platform computes a cryptographic hash and stores it against the item. That hash is a mathematical fingerprint: change one character in a document, and the fingerprint changes completely. At any later point — before production, before a deposition, or on the stand — you can re-run the hash and demonstrate the file is unchanged. This is the backbone of digital evidence integrity, and it lets an examiner speak to authenticity with confidence rather than assurances. Our work is backed by California BSIS PI License No. 190161, so the platform is built around the standards our own licensed investigators rely on.
Why does a clean audit log keep evidence admissible?
Before a court admits evidence, it wants to know that the item is authentic and that its handling can be accounted for. An append-only audit log answers both questions in one place: it shows an unbroken line of custody and demonstrates that no gap or unexplained access exists. Federal courts weigh authenticity under the rules of evidence, and a complete custody record is the most direct way to satisfy that threshold — you can read the framework at Federal Rule of Evidence 901. Because our custody tools live in the same platform as your case files, the record builds itself as your team works, rather than being reconstructed from memory later.
