Document authentication is accomplished by acquiring document image data, generating a set of features of the document, and generating an assist channel that includes information on how to generate the set of features. The bottom portions are pivotally connected and positioned perpendicularly with respect to one another for assembly of the hamper. The cover allows access to an existing power port while providing a plurality of connectors for connection to on-board systems. If so, a copy of the object is assigned to the cursor, and the copy is subsequently pasted at another location in the user interface upon the input control ceasing to be held after the cursor is moved to the other location. In the scan server of the present invention, scan setting and the OCR preprocessing are described in a scan ticket, and the image forming device performs, on a scanned image, the OCR preprocessing described in the scan ticket received from the scan server. When apertures are made in the relatively thick insulating film portions above the drain and source formation regions for the high-breakdown voltage transistor, etching is performed not to narrow widths of the sidewalls formed on the sides of the gate for the low-breakdown voltage transistor.
