Abstract

A device may comprise a display and a processor. The processor may obtain a first set of one or more touches on a remote surface of a remote device based on a signal received on a communication link between the device and the remote device. receive information associated with the first set of one or more touches through the signal. detect a gesture on the display, and determine whether the information is to be used to obtain content based on the gesture.

Claims

1. A method comprising:

detecting, by a device that includes a touch screen, information transmitted in response to a first set of one or more touches of a remote graphical object, on a remote device, where the first set of one or more touches form a first pattern;

identifying a first set of one or more parameters, associated with the first pattern, where the first set of one or more parameters are used to encrypt the information;

detecting a second set of one or more touches on the touch screen, where the second set of one or more touches form a second pattern;

identifying a second set of one or more parameters associated with the second pattern;

decrypting the encrypted information based on a comparison of the first set of one or more parameters to the second set of one or more parameters; and

providing the decrypted information to a user of the device.

2. The method of claim 1, where the encrypting information and the decrypting the encrypted information include:

identifying a gesture formed by the first set of one or more touches and by the second set of one or more touches.

3. The method of claim 2, where the information is transmitted, to the device, over a physical wireless communication link.

4. The method of claim 2, where identifying the first set of one or more parameters or the second set of one or more parameters includes at least one of:

measuring a duration of time to complete the gesture;

measuring a size of a finger for each touch;

measuring a speed of a finger movement;

measuring changes in capacitance of the display;

determining a shape of a finger for each touch;

measuring distances between fingers;

determining a fingerprint;

or

obtaining a three-dimensional image of a finger.

5. The method of claim 2, where identifying the gesture includes:

identifying the gesture as at least one of a one-finger gesture, a two-finger gesture, a continuous gesture, a discontinuous gesture, or as at least one tap.

6. The method of claim 1, further comprising:

receiving, from the device, a request for data that is referenced in the information; and

sending the data in response to the request.

7. The method of claim 6, where sending the data in response to the request includes:

sending the data over a communication link that is different from a wireless communication link over which the encrypted information is transmitted.

8. The method of claim 6, further comprising:

receiving, in response to sending the data, a payment at an account.

9. A device comprising:

a touch screen;

a memory to store a first set of one or more parameters associated with decrypting information; and

a processor configured to;

detect one or more touches on a remote radio-frequency identification (RFID) tag,

receive, in response to the one or more touches, encrypted information from the remote RFID tag,

identify a pattern formed by a gesture on the touch screen,

identify a second set of one or more parameters associated with the pattern,

decrypt the information based on a comparison of the first set of one or more parameters to the second set of one or more parameters associated with the pattern, and

provide the decrypted information to a user of the device.

10. The device of claim 9, where the remote RFID tag includes one of a passive RFID tag or an active RFID tag.

11. The device of claim 9, further comprising:

a RFID receiver for receiving the encrypted information.

12. The device of claim 9, where the processor is further configured to:

identify a link in the decrypted information;

download data from a location associated with the link; and

provide the data to the user.

13. The device of claim 12, where the processor is further configured to:

transfer a payment to an account in exchange for receiving the data.

14. The device of claim 12, where the processor is further configured to:

receive a discount coupon as the data.

15. A device comprising:

a display; and

a processor to;

obtain, by a signal received on a communication link between the device and a remote device, encrypted information from the remote device, where the encrypted information is encrypted based on a first set of one or more parameters that are associated with a first pattern, formed by a first set of one or more touches on a surface of the remote device;

detect a gesture on the display;

identify a second set of one or more parameters associated with a second pattern formed by the gesture;

decrypt the encrypted information based on the first set of one or more parameters, associated with the first pattern,

matching the second set of one or more parameters associated with the second pattern; and

provide the decrypted information to a user of the device.

16. The device of claim 15, where the remote device includes a passive radio-frequency identification (RFID) tag.

17. The device of claim 15, where the surface of the remote device includes a surface of a touch screen.

18. The device of claim 15, where the information includes a link to data at a content provider.

19. A device comprising:

means for receiving encrypted information that is transmitted from a remote device and that is associated with a graphical object at a remote display included in the remote device, where the information is encrypted based on a first set of at least one parameter;

means for detecting a pattern formed by a gesture on a local display;

means for identifying a second set of at least one parameter associated with the pattern;

means for decrypting the encrypted information based on a comparison of the first set of at least one parameter to the second set of at least one parameter associated with the pattern; and

means for providing the decrypted information to a user of the device.
