Abstract:
1. A data processing apparatus comprising: a registering unit configured to register a first processing mode in association with a first erasing method and to register a second processing mode in association with a second erasing method; a selecting unit configured to select one of the first processing mode and the second processing mode, the first processing mode comprising one of (i) a copy mode and (ii) a transmission mode, and the second processing mode comprising one of the copy mode and the transmission mode and being different from the first processing mode; a processing unit configured to process the image data in the one of the first processing mode and the second processing mode selected by the selecting unit; a specifying unit configured to automatically specify one of the first erasing method and the second erasing method, which is associated with the one of the first processing mode and the second processing mode selected by the selecting unit; and an erasing unit configured to erase the image data processed by the processing unit by using the one of the first erasing method and the second erasing method specified by the specifying unit, wherein each of the first erasing method and the second erasing method comprises a method for overwriting erasure data over data blocks of the image data stored in a storage unit, and wherein the second erasing method has a greater reliability than the first erasing method.
