Abstract:
1. An electronic device including a connecting unit configured to be connected with a storage medium that is removable, the electronic device transmitting data with the storage medium that is connected with the connecting unit, the electronic device comprising: a registration unit configured to register information that specifies the storage medium that is permitted to transmit data with the electronic device, among the storage media connected with the connecting unit; and a control unit configured to control whether to permit the electronic device to transmit data with the storage medium that is connected with the connecting unit based on the information that is registered in the registration unit, wherein the storage medium is allocated with identity information that is uniquely determined, the registration unit registers the identity information allocated to the storage medium in the electronic device as information that specifies the storage medium that is permitted to transmit data with the electronic device, the registration unit registers identity information allocated to the storage medium with which transmitting of data is not limited as first identity information, and identity information allocated to the storage medium with which transmitting of data is permitted only when the electronic device is used by a specified user as second identity information, the registration unit registers the identity information that is allocated to the storage medium permitted to transmit data with the electronic device and permission information that specifies a function permitted to be used, among functions provided in the electronic device, the identity information and the permission information corresponding to each other, the permission information including a first, a second, a third and a fourth sub-fields, wherein the first sub-field stores information that shows whether to permit printing data of the storage medium or not, the second sub-field stores information that shows whether to permit writing data of an image data that is read by an image reading unit in the storage medium or not, the third sub-field stores information that shows whether to permit reading data of the storage medium and storing the data in an image data storing unit, and the fourth sub-field stores information that shows whether to permit writing data stored in the image data storing unit in the storage medium or not; if the identity information that is allocated to the storage medium connected with the connecting unit belongs to the identity information registered in the registration unit, the control unit limits use of data transmitted with the storage medium connected with the connecting unit, which is performed using a function other than the function specified by the permission information corresponding to the identity information; and when the storage medium of the identity information that is not registered in the registration unit is connected with the connecting unit, it is only permitted to write the image data that is read by the image reading unit in the storage medium.
