Digital evidence that can prove it hasn't been touched.
TATHYA hashes every piece of digital evidence the moment it's collected, links each subsequent action into an immutable chain, and gives courts a way to verify — independently — that nothing was altered along the way.
The problem this replaces
Evidence gets tampered
Files copied between systems, re-saved, or edited lose their evidentiary value the moment their integrity can't be proven.
Chain of custody breaks
Manual custody logs — spreadsheets, paper registers — are themselves editable, and disputes over "who touched what, when" stall cases for months.
Cases collapse in court
Without a Section 65B-ready certificate and a defensible integrity trail, digital evidence can be challenged and thrown out entirely.
Built for every seat in the case
Investigating Officer
Register cases, collect and hash evidence on intake, and hand off a chain that's already verifiable — no extra paperwork.

Oversee every case in your jurisdiction, grant lawyers access to the right cases, and suspend accounts when needed.
Lawyer / Prosecutor
Pull court-ready evidence reports with IT Act section mapping, and verify integrity without ever needing write access.
Court Verifier
Look up any evidence ID and get an independent pass/fail integrity verdict plus the full access timeline — in seconds.
Real-time defensibility
When evidence is challenged, TATHYA recomputes every hash in its chain from scratch and produces a human-readable integrity trail — the same check a court can run independently.
