Abstract

A method for creating an electronic fingerprint for a mobile communication device, that includes receiving at a sensor, a first message from the mobile communication device, the first message comprising a mobile device identifier and a network identifier, sending to the server, a second message that comprises at least a part of the first message, and a sensor identifier, calculating a first fingerprint from the second message, and associating the first fingerprint with the a first unique identifier.

Claims

1. A method for creating an electronic fingerprint for a mobile communication device, comprising:

receiving at a sensor, a first message from the mobile communication device, the first message comprising a mobile device identifier and a network identifier;

sending to the server, a second message that comprises at least a part of the first message, and a sensor identifier;

calculating a first fingerprint from the second message; and

associating the first fingerprint with a first unique identifier.

2. The method of claim 1 further comprising:

comparing similarity level of the first fingerprint and a second fingerprint, the second fingerprint having a second unique identifier stored in the server;

associating the first fingerprint with the second unique identifier if the similarity level of the first fingerprint and the second fingerprint is at least above a predetermined threshold level; and

associating the first fingerprint with the first unique identifier if the similarity level is below the predetermined threshold level.

3. The method of claim 2, wherein the first and second unique identifiers are associated with a location of the mobile communication device.

4. The method of claim 1, wherein the first message includes an IEEE 802.11 based probe request.

5. The method of claim 1, wherein the sensor combines at least two first messages to form the second message.
