Abstract

An authentication process is provided which is rigid in terms of security and provides excellent usability to users. When an encrypted file is read from a secret folder or when a file is written into a secret folder, a file I/O is detected and blocked and an authentication is then performed. If the authentication is successful, the blocking of the file I/O is canceled and a common key established in the secret folder is used to decrypt the encrypted file to be read, or to encrypt the file to be written. The decrypted file is then provided to a user via an application or the encrypted file is then written into the secret folder. This series of processings is executed at every user login even in the case of the same secret folder used. That is, even after an authentication process was successful at the preceding login and a file I/O was permitted for a certain secret folder, once a logout is done, then a re-authentication process is executed at the next login.
