Identification of proximate mobile devices
First Claim
1. A method of identifying proximate mobile devices, the method comprising:
- providing a sensory identifier (ID) comprising two consecutive signals, when a first and second mobile device are proximate to each other;
the first mobile device detecting said providing of the sensory identifier (ID), said detecting producing a time stamp comprising a time interval between two consecutive signals;
the second mobile device detecting said providing of the sensory identifier (ID), said detecting producing a time stamp comprising a time interval between the two consecutive signals;
the first mobile device sending a request message (Q(ID)) associated with detection of the providing of the sensory identifier (ID) to the second mobile device; and
the second mobile device, upon receipt of the request message, sending an acknowledgement message (A(ID)) to the first mobile device so as to establish mutual identification when both the first and second mobile device have detected the same providing of the sensory identifier (ID).

Abstract
A method of identifying proximate mobile devices, the method comprising the steps of: providing a sensory identifier (ID), a first mobile device (1) detecting the sensory identifier (ID), a second mobile device (2) detecting the sensory identifier (ID), the first mobile device (1) sending a request message associated with the sensory identifier (ID) to the second mobile device (2), and the second mobile device (2) sending an acknowledgement message to the first mobile device (1) so as to establish mutual identification. The sensory identifier (ID) may comprise a visual identifier, such as a bar code, and/or an audio identifier, such as a sound signal. An audio identifier may be produced by tapping the mobile devices together.

25. A mobile device, comprising:
-
a detector configured to detect a sensory identifier (ID) comprising two consecutive signals, said signals generated when two of the mobile device are proximate to each other; a processor configured to execute software on non-transitory media, the software configured to produce a time stamp comprising a time interval between the two detected consecutive signals; a transmitter configured to send a request message (Q(ID)) associated with detection of the sensory identifier (ID) to another of the mobile device, and to send upon receipt of the request message, an acknowledgement message (A(ID)) to the device that sent the request message (Q(ID)), so as to establish mutual identification between two of the mobile devices, when both devices have detected the same sensory identifier (ID).
