Abstract

A secured communication channel is established between two or more information handling systems by defining attributes for encrypting information with physical inputs made at touch devices of the information handling systems. Inputting the physical gesture at a touch device of each information handling system allows evaluation of one or more attributes at each information handling system so that the shared secret of the physical gesture form the basis for encrypted communications. The touch device includes touch screens or touch pads and the attributes include gesture speed, plural distinct gesture touch points, movement of touch points relative to each other, or other attributes that are determinable from physical gesture inputs at each information handling system.

Claims

1. An information handling system comprising:

plural processing components operable to process information;

a touch device operable to accept one or more physical gestures of an end user and to save one or more predetermined attributes of the one or more physical gestures;

a security module interfaced with the touch device, the security module operable to apply the predetermined attributes to define a secured communication channel with one or more other information handling systems having physical attributes created with the same one or more physical gestures; and

a reference module operable to present a visual image as a reference for performing the one or more physical gestures at the touch device, the reference aiding input at the touch device of the same one or more physical gestures.

2. The information handling system of claim 1 wherein the touch device comprises a touch screen operable to present visual images.

3. The information handling system of claim 1 wherein the predetermined attributes comprise the speed of the gesture at the touch device.

4. The information handling system of claim 1 wherein the predetermined attributes comprise a number of distinct touch points.

5. The information handling system of claim 1 wherein the predetermined attributes comprise a predetermined rotational movement.

6. The information handling system of claim 1 wherein the secured communication channel comprises encrypted Transmission Control Protocol/Internet Protocol (“

TCP/IP”

) communications.

7. The information handling system of claim 1 wherein the secured communication channel comprises a wireless network.

8. A method for securely communicating information between plural information handling systems, the method comprising:

inputting a physical gesture at a touch device of a first information handling system;

presenting a visual image at a display of a second information handling system, the visual image providing a guide for performing the physical gesture at a touch device of the second information handling system;

inputting the physical gesture at the touch device of the second information handling system; and

creating a secure communication channel between the first and second information handling systems by encrypting and decrypting information communicated between the first and second information handling systems using one or more attributes of the physical gesture.

9. The method of claim 8 wherein the touch device comprises a touchpad that accepts mouse inputs.

10. The method of claim 8 wherein the touch device comprises a touch screen operable to present information as visual images.

11. The method of claim 8 wherein the physical gesture attributes comprise a speed of the physical gesture.

12. The method of claim 8 wherein the physical gesture attributes comprise a number of simultaneous touch points.

13. The method of claim 8 wherein the physical gesture attributes comprise a rotation of one or more touch points.

14. The method of claim 8 wherein the secure communication channel comprises a wireless interface between the information handling systems.

15. A system for secure communications between information handling systems, the system comprising:

a touch device operable to accept physical gesture inputs and to save attributes of the physical gesture inputs, the touch device having a display for presenting images;

a security module interfaced with the touch device and operable to apply the attributes to encrypt communications sent from the information handling system and to decrypt communications received at the information handling system; and

a reference module operable to present a reference image at the display, the reference image guiding an end user input of the physical gesture inputs.

16. The system of claim 15 wherein the attributes comprises motion of plural touch points relative to each other.

17. A method for securely communicating information, the method comprising:

presenting a visual image at a display of an information handling system, the visual image providing a guide for performing a physical gesture at a touch device of the information handling system;

inputting the physical gesture at the touch device of the information handling system; and

applying attributes of the physical gesture to generate an encryption key at the information handling system, the encryption key providing access to encrypted information of the information handling system.

18. An information handling system comprising:

plural processing components operable to process information;

a touch device operable to accept one or more physical gestures of an end user and to save one or more predetermined attributes of the one or more physical gestures;

a security module interfaced with the touch device, the security module operable to apply the one or more predetermined attributes to access encrypted information; and

a reference module operable to present a visual image as a reference for performing the one or more physical gestures at the touch device, the reference aiding input at the touch device of the one or more physical gestures.
