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.

Claims

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.
