AI Verification Infrastructure
Can you prove what your AI system did?
Evidentia turns AI outputs and usage records into independently verifiable Proof records without publishing raw customer data.

Scenario
AI-assisted risk review
A regulated company uses AI to support a risk review. The output may be useful, but a later audit asks a harder question. Can the original record be verified without trusting internal logs?
Sample data only. No raw sensitive customer data is shown or sent.Interactive proof flow
Logs explain. Evidence proves.
Run the sequence to see how a record becomes independently verifiable evidence.

The verification result confirms Proof metadata integrity. It does not judge whether the AI output was correct.
- Hash matches
- Signature valid
- Timestamp present
- Record unchanged
- Verification independent
