Method for increasing security in case of digital signatures using chip card, involves providing chip card with integrated display, terminal and chip card reading and writing device for transmitting data to be signed

摘要

The method involves providing a chip card (5) with an integrated display (51), a terminal (2) and a chip card reading and writing device (4) for transmitting data to be signed from the chip card to the terminal and from the terminal to the chip card. The data transmission between the chip card and the terminal is established, where display is visible to a user while data is transmitted between terminal and the chip card. A signature process is initiated for transmitting the data to be signed to the chip card, where the important data are marked. Independent claims are also included for the following: (1) a chip card with an integrated display for increasing security in the case of digital signatures (2) a system for increasing security in the case of digital signatures .
