| Capability | Persona | LKP |
|---|---|---|
| Returning user cost | $1.50 to $3.00+ per check | 0.5¢ (€0.005) per proof reuse |
| Data minimization | Collects high-resolution images & biometric meshes | Mathematical proof only (0 bytes raw PII) |
| Integration complexity | Complex workflow builder with enterprise setup | 3 simple API calls or 1 line of JavaScript |
| Sybil & duplicate account detection | Invasive tracking, fingerprinting, and PII matching | Cryptographic nullifier token with zero tracking |
| Pricing transparency | Custom quotes and annual minimum commitments | Transparent public pricing and 500 free reuses |

Frequently asked questions
Is LKP as secure as Persona?
LKP provides superior security against data breaches. Because user credentials are encrypted with AES-256-GCM in hardware passkey vaults and verified using Groth16 zk-SNARKs, there is no central database of unredacted identity documents for hackers to breach.
How does LKP verify age without seeing the exact birthdate?
Zero-knowledge proofs allow a user to mathematically prove the statement 'current_date - birth_date >= 18' is true without disclosing the actual date of birth or name.
