Product No. 1

Zero-knowledge smart visitor & interview registration for the AI era —verify, never expose.

Qingniu Dunan

The next-generation visitor management system for smart parks and enterprises: visitor reservations, interview registration, and unified park & enterprise management. Fully encrypted from booking, approval to access — data belongs to the park, the platform stays zero-knowledge.

What is zero-knowledge? Sensitive visitor data — name, ID, face — is encrypted at the source. The platform only stores ciphertext and can never read plaintext. Decryption keys are held solely by the park: data belongs to the park, and the platform knows nothing.
