ABSTRACT:
Smartcards are gaining acceptance as a secure medium for storing information, typically of a personal and confidential nature. Unfortunately, the process of storing information to the smartcard is a time consuming task, often taking much longer than to read the same amount of information from the card. The non-volatile memory within the smartcard is typically of the FLASH type and does not facilitate fast writing a fast writing process thereto. In order to speed up this process, a comparative writing algorithm is utilized which only writes changed data to the smartcard memory, thus eliminating the need for storing duplicate information.
