Abstract
A data protection method includes generating a decryption key acquisition request through a first operation account when encrypted data is received, obtaining the decryption key from a data security area through a second operation account in response that the decryption key acquisition request is an authorized request, using the decryption key to decrypt the encrypted data through the first operation account and obtaining decrypted data, mounting a data partition, and storing the decrypted data in the data partition through the first operation account.
