The Fake BTS Detection and Location On Smart Phones

Fake BTS uses a lack of security mechanisms of GSM network to directly attack users by sending spam and fraud SMS messages. The traditional methods of detection are that the police or the operators go for investigation after receiving the report. This method's success rate is poor because Fake BTS is of high mobility. In this paper, we develop an effective detection and location method based on Android operating system. In particular, our detection method is based on abnormal ratio of signal intensity. Additionally, we present a novel method for accurately locating Fake BTS while incurring negligible impact on end-user devices. Our application will help users away from millions of spam and fraud SMS messages per day. Meanwhile, our location algorithm will help the police arrest hundreds of illegal operators.
