Abstract
In a data encryption method, a request to input an encryption password set is made upon receipt of an encryption request to encrypt data, and the data are encrypted such that the encrypted data can be decrypted using one of the encryption password set and a predetermined supervisor password set upon receipt of the encryption password set. Thus, during decryption, one of the encryption password set and the supervisor password set can be used for decryption, thereby providing a restoring mechanism.
