Abstract: A data management device includes a converter and a storage unit. The converter, in response to an instruction to move image data of a first format generated by image capture by an image capture unit and stored in a predetermined first memory area to a second memory area, converts the image data from the first format to a second format. The storage unit stores the image data converted into the second format in the second memory area. The converter does not perform the conversion in the case in which the storage source of the image data to be moved is not the first memory area.

Abstract: A reading system includes a reading apparatus and a terminal apparatus. The reading apparatus includes following components. An identification unit identifies a first user. A reading unit reads an original document. A reception unit receives, from the terminal apparatus, authentication information of a second user and an instruction. An authentication unit performs authentication using the authentication information. A permission unit permits, if authentication is successful, the reading unit to read an original document in accordance with the instruction. The terminal apparatus includes following components. A first acquisition unit acquires, from the reading apparatus, identification information of the first user. The acceptance unit accepts an operation of the second user. The second acquisition unit acquires identification information of the second user.
