Abstract
When a valid password is input by a user having a right to access a folder, a decrypted document and image for view are produced from an encrypted document included in the folder and stored in the folder such that they are correlated with the encrypted document. If a request to view a document in this folder is issued by a user having a right to access the folder, a corresponding image for view is displayed on a terminal of the issuer of the request. When a request to acquire a document in the folder in order to save it is issued, a corresponding encrypted document is transmitted to a terminal of the issuer of the request. In a case where a request to acquire a document in the folder in order to print it is issued, a corresponding decrypted document is transmitted to an terminal of the issuer of the request.
