Comparison
Vishwaas AI vs KavachOne.
Both record consent. Only one makes alteration self-evident.
Both platforms record that consent happened. The question a DPBI inquiry asks is different: can you prove the record wasn't changed afterwards? That comes down to the evidence mechanism — so we compare mechanisms, not slogans.
The real question
Recording consent is easy. Proving it is the product.
A timestamp-and-IP log records that consent happened. It does not prove the record is the same one written that day. Under DPDP, that distinction is the difference between an assertion and evidence.
| Criterion | KavachOne | Vishwaas AI |
|---|---|---|
| Consent evidence mechanism | ✕Timestamp + IP log | ✓SHA-256 hash chain + RSA signatures + RFC 3161 timestamps |
| Tamper-evidence | ✕None — rows can be edited in place | ✓Any post-hoc change visibly breaks the chain |
| DBA can silently alter a record | ✕Yes — flag and timestamp are mutable | ✓No — append-only retention refuses UPDATE/DELETE |
| Independent verification | ✕Trust the vendor's database | ✓Independently verifiable against the chain + RFC 3161 timestamp |
| India data residency | ✕Varies / not guaranteed | ✓ap-south-1, no cross-border transfer |
| Consent Manager (Rule 4) posture | ✕Unstated | ✓India-incorporated, built to register |
| 22-language notices | ✕English-first, manual translation | ✓Native Eighth Schedule coverage |
Why it matters
A record you can edit is an assertion — not proof.
Picture the inquiry, not the demo.
The DPBI inquiry scenario
A data principal complains that they never consented to a marketing purpose. The Board asks for the consent record. You produce a row: granted, a timestamp, an IP address. The Board's next question is the one that matters — how do we know this row wasn't written last week? With a timestamp-and-IP log, you cannot answer it; the row is exactly as easy to fabricate after the fact as it was to capture at the time. With a hash chain, the answer is structural: this record carries the hash of the one before it, an RFC 3161 authority countersigned the time, and any later edit breaks every link downstream. The record stops being something the regulator has to take on trust and becomes something they can independently verify.
