Privacy information management method and device, computer equipment and storage medium

The invention discloses a privacy information management method and device, computer equipment and a storage medium, and belongs to the technical field of big data and the field of financial science and technology. The to-be-encrypted data matched with the data encryption instruction is identified, the first secret key is utilized to encrypt the to-be-encrypted data, the first secret key and the ciphertext data are sent to the second client, the first ciphertext data are decrypted by using the first secret key, the to-be-hidden data matched with the data hiding instruction in the first ciphertext data are identified, and the to-be-hidden data in the first ciphertext data are hidden. And encrypting the to-be-hidden data by using the second key, and after the encryption is completed, sending the second key to a key management center. The invention further relates to the technical field of block chains, and the first public key can be stored in a block chain node. According to the data management method and devi
