METHOD AND SYSTEM FOR INCREASING SECURITY IN THE CREATION OF ELECTRONIC SIGNATURES BY MEANS OF A CHIP CARD
First Claim
1. Method for increasing security in the creation of electronic signatures with a chip card (5) comprising the steps of:
- a) providing a chip card (5) with integrated display (51),b) providing a terminal (2) and a chip card reader/writer (4) for transmitting data to be signed from the chip card (5) to the terminal (2) and from the terminal to the chip card, respectively,c) establishing data communication between the chip card (5) and the terminal (2), with the display (51) being substantially visible to the user during data communication between the terminal (2) and the chip card (5),d) initiating a signature process,e) transmitting to the chip card (5) the data to be signed wherein essential components may be characterized by marks,f) selecting essential data from the data to be signed by means of a selection means on the chip card,g) representing the selected data on the display (51) of the chip card, andh) signing the data to be signed, with the signature being transmitted from the chip card (5) to the terminal (2).

Abstract
The present invention relates to a method and system for increasing security in digital signatures by means of chip card. The method and system of the invention in particular provide for a visual verification of the data to be designed and select essential data therefrom in order to ensure a reliable signing process. The method for increasing security in the digital signing of data with a chip card comprises the following steps: providing a chip card (5) with integrated display (51), providing a terminal (2) and a chip card reader/writer (4) for transmitting data to be signed from chip card (5) to terminal (2) and from the terminal to the chip card, respectively, establishing a data transmission between chip card (5) and terminal (2), with display (51) being substantially visible to the user during data transmission between terminal (2) and chip card (5), initiating a signature process, transmitting the data to be signed to chip card (5), with the essential data being marked, and selecting the marked data, representing the selected data on display (51) of the chip card, and signing the data to be signed, the signature being transmitted from chip card (5) to terminal (2).

2. Method for increasing security in the creation of electronic signatures with a chip card comprising the steps of:
-
providing a chip card (5) with integrated display (51), said chip card being adapted to a pre-determined signature process, providing a chip card reader/writer (4) with visual access to the integrated chip card display (51), said chip card reader/writer being adapted to a pre-determined signature process, establishing data transmission between the chip card reader/writer (4) and the chip card (5), initiating the pre-determined signature process, transmitting the data to be signed from the chip card reader/writer (4) to the chip card (5), marking essential data from the data to be signed, selecting the essential data based on the mark(s), the selection being performed by means of a selection means on the chip card itself, representing these selected data on the display (51) of the chip card (5), signing the data to be signed, with the signature being transmitted from the chip card (5) to the terminal (2).
