Abstract: An information processing device may include a data memory configured to store a security datum; a program memory configured to store a processing program; and a processor configured to execute the processing program. The processing program requires the security datum to execute the processing program. The security datum is stored at a memory address in the data memory. The program memory is configured to store a reference address table linking the security datum with the memory address in the data memory at which the security datum is stored. The processor is configured to, when executing the processing program, access the reference address table to identify the memory address of the security datum corresponding to the processing program, access the required security datum at the memory address, and execute the processing program. The reference address table is different from a second reference address table in a second information processing device.

Whether or not the medium is ejectable is determined by transporting the medium in the ejecting direction by means of the transporting means. The media information stored in memory is controlled so as to be deleted when it is determined that the medium is not ejectable. In this way, as long as it is not confirmed that the medium is ejectable, the media information recorded in the medium is not output to the host device.

Abstract: A method for downloading software from a host device to an electronic device through a communication line, which, even when the download is interrupted, can simplify the procedure to restart the download while maintaining security. In the method, a certificate of authenticity data, which the card reader has obtained from the HOST computer, is stored in the non volatile memory. The download of the software from the HOST computer to the card reader is executed. The verification of authenticity data is obtained by calculation with respect to the downloaded software. This verification of authenticity data is then compared with the certificate of authenticity data obtained from the HOST computer, and the downloaded software is run when the certificate of authenticity data matches the verification of authenticity data.
