发明名称 IMAGE FORMING APPARATUS AND METHOD OF USER AUTHENTICATION
摘要 An image forming apparatus includes a user authentication function that authorizes a user to operate saved print data with a password without requiring an input of the password while ensuring a security level. When a user is going to operate a document by using the image forming apparatus, and if the user logged in the image forming apparatus is a creator of the document, the image forming apparatus performs control not requiring the user to input an operation password for print data. Moreover, by managing information on users who have unlocked the operation password as document information, the image forming apparatus also performs control not requiring even users other than the creator of the document to input the operation password if the users have unlocked the operation password ever before.
