Qingniu Dunan

The Qingniu Dunan zero-knowledge platform serves enterprises and individuals alike: one-stop coverage of visitor registration, interview registration, and encryption protection for core data assets. Built on zero-knowledge technology to make data usable yet invisible — with isolated privacy, end-to-end audit trails, and compliance-grade traceability, safeguarding sensitive information for both government & enterprises and individuals.

What is zero-knowledge? Sensitive data — across visitors, interviews and core assets — is encrypted at the source. The platform only stores ciphertext and can never read plaintext. Decryption keys are held solely by the customer: data belongs to the customer, and the platform knows nothing.
