A control method for an image forming apparatus configured to perform transmission of information includes performing retransmission of the information a predetermined number of times in a case where the transmission of the information fails, wherein an entry about the retransmission of the information is added to a notification table managed by the image forming apparatus, clearing the entry from the notification table, in a case where the retransmission of the information is completed the predetermined number of times or a case where the image forming apparatus receives a response to the retransmission of the information, and clearing the entry from the notification table in a case where user information necessary for the retransmission of the information is changed.

An image forming device executes a plurality of applications, and includes a scan controlling unit configured to instruct an image reading unit to read image data, and store the image data in an image data storage unit according to a request from the application; a display data generating unit configured to generate a display data of the image data stored in the image data storage unit, and store the display data in a display image data storage unit according to the request from the application, the display image data storage unit being inaccessible from the application; a display controlling unit configured to display the display data in a display unit according to the request from the application; and a deleting unit configured to delete the display data from the display data storage unit in response to a termination notice of use of the display data from the application.

A data communication apparatus which does not have a function for receiving, via a mail server, e-mail sent by an external device includes a setting unit configured to set a POP account for the mail server, a reading unit configured to read a document to generate image data, a sending unit configured to send the generated image data as an e-mail via the mail server after performing authentication based on the POP account set by the setting unit, and a notification unit configured to transmit to the mail server, a delete instruction to delete an e-mail stored in a mailbox on the mail server.

In a digital camera having a wireless communicator with a server, a storage controller treats full size image data and display size image data unequally if the full size image data has been already sent to the server. For example, the display size image data is not allowed to be replaced by new digital image data unless the digital camera is not in use over a prescribed time. Own image data and other's image data are treated equally. Image data received from outside and retrieved from inside memory are treated equally. Search key for own image data and related search keys existing in the outside are indicated in a comparable manner. The digital camera receives search key from neighboring advertiser to send it for Internet search of advertisement. Search key received from neighboring notable site is sent for Internet search of photographs of the notable site taken by others.

A read unit of a scanner device reads the information fixed to a medium by printing. A transmission control unit executes the control of transmitting, to a server, the information of the medium acquired in the form of digital image data. An information acquisition unit acquires the information transmitted from a shredder. An information management unit stores the information acquired by the information acquisition unit in an acquired information database in such a way as to be identified as the information of the medium so as to be managed to be capable of being read out as the information of the medium. An information readout unit acquires a readout indication transmitted from an observer terminal. Then, the information readout unit reads the information of the medium out of the acquired information database via the information management unit.

An information processing apparatus is provided. The apparatus generates a name using characters recognized in image data, assign the name to the image data, and store the image data; makes a request for approval by a user regarding the name, transmit the image data to an external apparatus after the image data is approved by the user, and deletes the image data; in a case where the image data has exceeded a predetermined storage period without the name being approved by the user, in a case where the name satisfies a predetermined condition, transmits the image data to the external apparatus before deleting the image data; and deletes the image data that has exceeded the predetermined storage period without the name being approved by the user.

An image forming apparatus stores image data generated from a document scanned by a scanner on a removable medium. When storage on the removable medium is not completed, part of the image data that has been stored by that time is deleted from the removable medium.

An image forming apparatus includes a state management unit that shifts an authentication state from a non-login state to a login state, a storage unit that stores setting information, and a data management unit that, in a case where a free space of the storage unit is less than a threshold value, deletes the setting information stored in the storage unit at a timing of shifting from the non-login state to the login state and secure a free space greater than or equal to the threshold value in the storage unit.
