Abstract

According to an aspect of the invention, a security token is conceived, in particular a smart card, comprising a tactile sensing user interface, wherein said tactile sensing user interface is adapted to capture a stream of position data corresponding to a sequence of positions of a finger engaging with said tactile sensing user interface and representing a stream of input data for a data processing device, said security token being adapted to transmit said stream of position data to a host system for further processing.

First claim

The invention claimed is:

1. A security token, in particular a smart card, comprising a two-dimensional tactile sensing user interface and an NFC interface, wherein said two-dimensional tactile sensing user interface is adapted to capture a stream of two-dimensional position data corresponding to a sequence of positions of a finger engaging with said two-dimensional tactile sensing user interface and representing a stream of input data for a host application running on a data processing device of a host system, said security token being adapted to transmit said stream of two-dimensional position data to said host system via said NFC interface for further processing.

2. A security token as claimed in claim 1 , further being adapted to encrypt the stream of two-dimensional position data before transmitting said stream of position data to the host system.

3. A security token as claimed in claim 1 , further being adapted to format the stream of two-dimensional position data as application protocol data units before transmitting said stream of position data to the host system.

4. A security token as claimed in claim 1 , further being adapted to provide a single-factor or multi-factor user authentication function.

5. A data processing system comprising the security token as claimed in claim 1 and the host system, wherein the host system comprises a data processing device, and wherein the host system is adapted to receive the stream of two -dimensional position data via the NFC interface and to convert said stream of two-dimensional position data into the stream of input data for said data processing device.

6. A data processing system as claimed in claim 5 , wherein the host system comprises a computer program or a secure element for converting said stream of two-dimensional position data into the stream of input data for said data processing device.

7. A data processing system as claimed in claim 5 , wherein the input data comprise alphanumeric symbols.

8. A data processing system as claimed in claim 5 , wherein the input data comprise data representing a movement of a pointing device and/or data representing a selection operation performable on a pointing device.

9. A data processing system as claimed in claim 5 , wherein the input data comprise special keys as defined on a keyboard and/or special character keys as defined on a keyboard.

10. A data processing system as claimed in claim 5 , wherein the data processing device is one of the group of: a personal computer, a portable computer, a web tablet, a terminal, a mobile device, a vehicle, an industrial process control device.

11. A method of processing data, wherein a two-dimensional tactile sensing user interface comprised in a security token, in particular in a smart card, captures a stream of two-dimensional position data corresponding to a sequence of positions of a finger engaging with said two-dimensional tactile sensing user interface and representing a stream of input data for a host application running on a data processing device of a host system, and wherein the security token transmits said stream of position data to the host system via an NFC interface for further processing.

12. The method of claim 11 , wherein the input data comprise data representing a movement of a pointing device and/or data representing a selection operation performable on a pointing device.
