A user is enabled to easily access a data area on a network, and to use the data area with security, wherein a recording medium records an address for accessing a prescribed area of a storage apparatus installed in an other apparatus and keys to be used for encrypting data. When the recording medium is installed in the apparatus, the address is read-out from the recording medium and, based on the read-out address, accessing to the prescribed area is started. When the user actually accesses the recording medium, the prescribed area is accessed. In the apparatus to which the recording medium is installed, processing such as a path conversion is carried out as required so that the user is able to operate without mentioning such procedure.
