Store-Network License, Hygiene & Insurance Compliance
Verify that each store in a chain or franchise validly holds the required licenses, food-hygiene, and insurance without receiving the originals, and because revocation stays trackable, you can confirm not just what was submitted but that it is valid now.
🔔 Plan · Lemma Compliance →For chain HQ and area managers
Verify licenses, food-hygiene, and insurance across many stores without collecting certificate PDFs — eliminating forgery, expiry, and reuse risk.

Each store presents only a proof that it "validly holds the required license, hygiene, and insurance." Originals aren't handed over. Attributes are issuer-signed; HQ and auditors verify without seeing the contents, and revocation (expiry, withdrawal) is trackable.
(A lawful verification process for each license/insurance is assumed.)
Choose on three criteria.
Only work that needs all three at once — pass without exposing, independent verification, tamper-proof — is Lemma's domain.
| Method | Pass without exposing | Independent verification | Tamper-proof |
|---|---|---|---|
| Access control only | △ | ✗ | ✗ |
| Masking / anonymization | △ | ✗ | ✗ |
| Encryption only | ✓ | ✗ | ✗ |
| Lemma (ZK proof)the only one with all 3 | ✓ | ✓ | ✓ |
What's next
We enter through AI-adoption and data-governance support and a PoC, and stay alongside you through to operations.
- A 30-minute review — identify checks where forgery/expiry risk concentrates.
- Narrow to 1–2 decisions to prove — e.g. "holds a valid permit," "insurance valid." Not the originals.
- Design issuers and revocation — connection to government/insurer/hygiene issuers, expiry/revocation handling.
- Prove one path via a (quote-based) PoC.
- Hands-on support from rollout through operations — existing plan tiers (Civic / Critical / Compliance) serve only as a cost reference; setup and pricing are designed together.
Tell us the one license with the heaviest verification risk, in the first 30 minutes. No disclosure of sensitive data required.
