<p>A method and apparatus is provided for managing private data, such as a phone book, in a multi-function product (MFP) used by multiple users. The method involves receiving user information (500) and performing user authentication (510), and reading data (530) stored in a user area allocated to the authenticated user in a storage unit (130, 450) divided into a number of user areas (200, 210, 220 ...). Accordingly, when private data is managed in an MFP used by multiple users, by dividing a storage unit in which data is stored into a number of user areas, allocating the divided user areas to users, and allowing a user to access only a user area allocated to the user through an authentication process, the private data can be fully prevented from being accessed by other users, and it will be unlikely for a user to be confused because of other user data.
