Abstract:
1. A data communication apparatus comprising: an acquiring device that acquires a key to be used for encryption; a searching device that searches at least one encryption scheme corresponding to the key acquired by said acquiring device; a setting device that sets a threshold value of a period of time required for the encryption; a calculating device that calculates, based on a data size of a scanned image file to be transmitted, a period of time required for encryption of the scanned image file to be transmitted, the encryption of the scanned image file being performed by the encryption scheme searched out by said searching device; a first determining device that determines whether or not the period of time calculated by said calculating device is shorter than the threshold value set by said setting device; a display device that displays the encryption scheme together with the period of time required for encryption of the scanned image file as a selectable candidate when the period of time calculated by said calculating device is determined to be shorter than the threshold value; a second determining device that determines the encryption scheme as the encryption scheme for encryption of the scanned image file to be transmitted when the selectable candidate is selected by a user; and a transmission device that transmits the image file encrypted by the determined encryption scheme to the outside of the data communication apparatus, by using the key acquired by the acquiring device, wherein the data communication apparatus is a copier, a printer, a scanner, a facsimile machine, or a multi-function machine that performs at least two functions selected from the group consisting of copying, printing, scanning, and faxing.
