Data security authentication system and related multi-function memory card and computer program product

摘要

A multi-function memory card is disclosed including: a memory card interface for coupling with a memory card connection port of a terminal device; a storage module for storing one or more specific files transmitted from the terminal device; a protocol converter for retrieving the one or more specific files from the storage module and extracting data contained in the one or more specific files; and a smart card module for conducting an operation on extracted data from the protocol converter using a private key to generate one or more response data and transmitting the one or more response data to the protocol converter; wherein the protocol converter converts the one or more response data into one or more response files and writes the one or more response files into the storage module so that the one or more response files are accessible by the terminal device.

1. A data security authentication system comprising:
a terminal device comprising: a memory card connection port; and a processor module, coupled with the memory card connection port, for converting one or more data into one or more specific files and writing the one or more specific files into a storage module via the memory card connection port; the one or more specific files written to a specific physical address if it has a predetermined filename or extension and to other physical address if it doesn't have a predetermined filename or extension; anda multi-function memory card comprising:
a memory card interface for coupling with the memory card connection port; the storage module, coupled with the memory card interface, for storing the one or more specific files; a protocol converting circuit, coupled with the storage module, for retrieving the one or more specific files from the storage module based on the filename or extension which is associated with the specific physical address and extracting data contained in the one or more specific files; and a smart card module, coupled with the protocol converting circuit, for conducting an operation on extracted data from the protocol converting circuit using a private key to generate one or more response data and transmitting the one or more response data to the protocol converting circuit; wherein the protocol converting circuit converts the one or more response data into one or more response files and writes the one or more response files into the storage module, then the processor module reads the one or more response files from the storage module via the memory card connection port and extracts the response data contained in the one or more response files.
