ABSTRACT:
An end-user oriented, file encryption control apparatus and method involving simple manipulations. File encryption is performed by conducting intuitive drag and drop manipulation with respect to an icon modeled after a safe. From the password for user authentication, an encryption key used for file encryption and decryption is automatically generated. All manipulations concerning the encryption key are concealed from users. A user interface section for performing encryption and decryption by conducting intuitive drag and drop manipulation with respect to an icon modeled after a safe, an automatic encryption key generation section for automatically generating an encryption key from a password, and a file encryption processing section for conducting file encryption processing without conducting authentication using a password are included. A file encryption function excellent in manipulation convenience is thus provided.
