METHOD FOR CONTROLLING IC CARD DATA BROWSING, INFORMATION TERMINAL EQUIPMENT, COMPUTER PROGRAM AND SERVER

摘要

PROBLEM TO BE SOLVED: To safely browse data in an IC card even at the time of the off-line of information terminal equipment. SOLUTION: The user of a mobile device (information terminal equipment) downloads an enciphered viewer script 90 for browsing data in an IC card built in or mounted on the mobile device from a server. This encipherment is performed based on a PIN(personal identity number) inputted by a user. The mobile device receives the compressed and enciphered viewer script 90, and stores the enciphered viewer script 90 in a non-volatile memory 14 as it is. Thereafter, at the time of browsing the IC card data off-line, a viewer script 93 obtained by decoding and defrosting the viewer script 90 based on the inputted PIN is analyzed and executed by a viewer engine so that a standard HTML(hypertext makeup language) document 95 can be generated. Immediately after the HTML document 95 is generated, the scripts 93 (and 91) are erased. The HTML document 95 is displayed at a display by a normal browser function.
