Abstract
Upon data access, an attribute-data extraction unit extracts location data and a password from attribute data which is added in advance to subject data to be accessed. At the time of requesting for an access to the data, the extracted password is compared with a password which is inputted from an input unit, and the extracted location data is compared with current location data detected by a location-data detection unit. An access permission unit permits access to the data in accordance with the comparison results obtained by the password comparison unit and the location-data comparison unit. By virtue of the process, it is possible to more strictly protect confidential information in a data processing apparatus.
