Comparison
Vishwaas AI vs Redacto.
'Prove it' is our architecture, not our tagline.
Every privacy vendor says their consent records are defensible. Few will tell you the mechanism. Our whole pitch is that you should never take a proof claim on trust — including ours. So here is the named architecture behind every claim, and an invitation to ask any vendor for the same.
Named, not narrated
If a vendor can't name the mechanism, there isn't one.
The test is simple: ask what cryptographic mechanism makes the record tamper-evident. A named standard you can verify is a different thing from an unspecified promise of 'proof'.
| Criterion | Redacto | Vishwaas AI |
|---|---|---|
| Consent evidence mechanism | ✕Unspecified 'audit trail' | ✓Named: SHA-256 hash chain + RSA signatures + RFC 3161 |
| Tamper-evidence | ✕Asserted, not demonstrated | ✓Structural — a broken chain is visible to any verifier |
| Independent verification | ✕Requires trusting the vendor | ✓Independently verifiable without trusting Vishwaas |
| Trusted timestamp authority | ✕Not stated | ✓RFC 3161 third-party timestamp on every event |
| Storage model | ✕Standard mutable database | ✓Append-only retention — the ledger only grows |
| India data residency | ✕Varies / not stated | ✓ap-south-1, no cross-border transfer |
The four mechanisms
Every proof claim we make, named.
Ask any vendor to match this list, item for item.
SHA-256 hash chain
Each consent record carries the SHA-256 hash of the record before it. Change any record after the fact and the chain visibly breaks at that position and every position after — tampering stops being deniable.
RSA digital signatures
Each record is signed with RSA-2048 keys held inside an AWS KMS HSM. The signature is cryptographic proof of origin and integrity — and the signing key never leaves hardware.
RFC 3161 trusted timestamps
An independent timestamp authority countersigns each event, binding it to calendar time. Verification never depends on trusting Vishwaas — it stands on the third-party timestamp.
Append-only retention
Schema-level enforcement refuses UPDATE and DELETE on consent records. Even a database administrator cannot backdate or remove a row — the ledger only grows for the full 7-year retention.
