Method of determining fraudulent use based on behavioral abnormality starts with processor receiving first location data and first proximity information from first mobile device. First proximity information includes identification of mobile devices within proximity sensitivity radius of first mobile device. Processor determines whether first location data and first proximity information are included in historical location data and historical proximity information, respectively, associated with first mobile device. When first location data and first proximity information is not included, processor determines whether subsequent location data and subsequent proximity information received from first mobile device over predetermined period of time is included. Processor signals to monitor fraudulent use of first mobile device when subsequent location data and subsequent proximity information received from first mobile device over predetermined period of time is not included in historical location data and historical proximity information, respectively, associated with first mobile device. Other embodiments are described. |

1. A method of determining fraudulent use of a first mobile device based on behavioral abnormality, the method comprising:
receiving, by a processor, a first location data and a first proximity information from the first mobile device, wherein the first proximity information includes an identification of mobile devices that are within a proximity sensitivity radius of the first mobile device; displaying, by a display device, the first mobile device's location based on the first location data; determining, by the processor, whether the first location data and the first proximity information are included in a historical location data and a historical proximity information, respectively, associated with the first mobile device, wherein the historical location data and the historical proximity information associated with the first mobile device is included in a historical database; and when the first location data and the first proximity information are not included in the historical location data and historical proximity information, respectively, associated with the first mobile device,
monitoring, by the processor, a fraudulent use of the first mobile device including: determining, by the processor, whether subsequent location data and subsequent proximity information received from the first mobile device over a predetermined period of time are included in the historical location data and historical proximity information, respectively, associated with the first mobile device; updating, by the processor, the historical database by storing the first location data and the first proximity information in the historical location data and historical proximity information, respectively, associated with the first mobile device, when the subsequent location data and the subsequent proximity information received from the first mobile device over the predetermined period of time is included in the historical location data and historical proximity information, respectively, associated with the first mobile device; and; signaling, by the processor, a fraudulent use of the first mobile device when the subsequent location data and the subsequent proximity information received from the first mobile device over the predetermined period of time are not included in the historical location data and historical proximity information, respectively, associated with the first mobile device. |
