Sending verification password responsive to mobile device proximity

1. A method, comprising:

detecting proximity between a mobile device and a remote device associated with a transaction reserved by a user of the mobile device, wherein detecting the proximity comprises:

detecting a first location of the mobile device;

extracting a verification password and a second location associated with the transaction from a document on the mobile device associated with the transaction; and

comparing the first and second locations to determine the proximity; and

sending the verification password to the remote device responsive to detecting the proximity.

2. The method of claim 1 , wherein detecting the proximity further comprises detecting context information associated with the device indicative of transaction engagement.

3. The method of claim 2 , wherein detecting the context information comprises detecting a transition between a walking mode of the mobile device and a driving mode of the mobile device.

4. The method of claim 2 , wherein detecting the context information further comprises:

monitoring a current noise profile of the mobile device; and

comparing the current noise profile to at least one reference noise profile associated with the service.

5. The method of claim 1 , wherein sending the verification password comprises sending a text message to the remote device.

6. The method of claim 1 , wherein sending the verification password comprises sending an audio message to the remote device.

7. The method of claim 1 , wherein the document comprises one of a web document, a text message, or an email message.

8. A device, comprising:

a module to detect proximity between the device and a remote device associated with a transaction reserved by a user of the device, the module comprising a location module to detect a location of the device; and

a processor coupled to the module, wherein the processor is to detect a first location of the device using the location module, extract a verification password and a second location associated with the transaction from a document on the mobile device associated with the transaction, compare the first and second locations to determine the proximity and, send a verification password to the remote device responsive to detecting the proximity.

9. The device of claim 8 , wherein the module comprises a proximity communication module to communicate with the remote device to determine proximity to the remote device.

10. The device of claim 8 , wherein the processor is to detect context information associated with the device indicative of transaction engagement and send the verification password to the remote device responsive to detecting the proximity and based on the context information.

11. The device of claim 10 , further comprising a motion sensor coupled to the processor, wherein the processor is to detect the context information using data from the motion sensor to detect a transition between a walking mode of the device and a driving mode of the device.

12. The device of claim 10 , further comprising a microphone coupled to the processor, wherein the processor is to detect the context information using data from the microphone to monitor a current noise profile of the device and compare the current noise profile to at least one reference noise profile associated with the service.

13. The device of claim 8 , wherein the processor is to send the verification password by sending a text message to the remote device.

14. The device of claim 8 , wherein the processor is to send the verification password by sending an audio message to the remote device.

15. The device of claim 1 , wherein the document comprises one of a web document, a text message, or an email message.

16. A method, comprising:

detecting proximity between a mobile device and a remote device associated with a transaction reserved by a user of the mobile device, wherein detecting the proximity comprises:

detecting a first location of the mobile device;

receiving a second location associated with the transaction in the mobile device;

comparing the first and second locations to determine the proximity; and

detecting context information associated with the device indicative of transaction engagement by detecting a transition between a walking mode of the mobile device and a driving mode of the mobile device; and

sending a verification password to the remote device responsive to detecting the proximity.

17. The method of claim 16 , wherein sending the verification password comprises sending a text message to the remote device.

18. The method of claim 16 , wherein sending the verification password comprises sending an audio message to the remote device.

19. The method of claim 16 , wherein the document comprises one of a web document, a text message, or an email message.

20. The method of claim 16 , wherein detecting the context information further comprises:

monitoring a current noise profile of the mobile device; and

comparing the current noise profile to at least one reference noise profile associated with the device.
