1. A data transfer control device that has a controller and that controls transfer of data stored in a memory device in response to a data transfer request,
wherein the controller is configured to:
generate tag information in response to receiving a tag generation request, encrypt the tag information, and transmit the encrypted tag information to a device from which the tag generation request was transmitted,
process data stored at a predetermined address to generate data for transmission in a case in which an address at which data related to the data transfer request is stored includes the predetermined address, the data for transmission comprising data to be transmitted to the device, and the controller being configured to process the data stored at the predetermined address by deleting the data stored at the predetermined address from the data related to the data transfer request such that the data stored at the predetermined address is not included in the data for transmission, and
using the tag information, scramble or encrypt the data for transmission having been processed to delete the data stored at the predetermined address, and transmit the scrambled or encrypted data to the device.
