A method for managing data includes obtaining output device information from an external device, the output device information concerning an output device to which the external device outputs data, upon detecting access to the data stored in a storage device from the external device, estimating, using a processor, a first user who has viewed the data output to the output device based on a relationship for each of the output device information between the first user and a second user who uses the external device, and generating association information which associates the data with identification information identifying the first user to store the association information in the storage device. |
