Face anti-spoofing methods help ensure that no data gets into the wrong hands. So, if you want to protect your (clients’) data, don’t forget to power up your system with liveness detection or let us develop a reliable solution for you.

The systems could be patch to send an alarm when the GPS-calculated jumps by an unreasonable amount, and transmit both the old (last known position) and new positions to the base station. Design and Performance Evaluation of GPS Spoofing Signal Detection Algorithm at RF Spoofing Simulation Environment Soon, Lim1 ; Deok Won, Lim ; Sebum, Chun ; Moon Beom, Heo ; Yun Sub, Choi ; Ju Hyun, Lee ; Sang Jeong, Lee Disclosed herein are system, method, and computer program product embodiments for detecting spoofing of a navigation device. A plurality of anti-spoofing techniques are provided. The plurality of anti-spoofing techniques detect interference with data provided by one or more navigation devices for a plurality of threat situations. Spoofing attacks had been predicted and discussed in the GPS community, but no known example of a malicious spoofing attack has yet been confirmed. However, some analysis suggests that the capture of a Lockheed RQ-170 drone aircraft in northeastern Iran in December 2011, was the result of such an attack. how typical civil GPS receivers respond to an advanced civil GPS spoofing attack, and four techniques to counter such attacks: spread-spectrum security codes, navigation message authentication, dual-receiver correlation of military signals, and vestigial signal defense.

Figure 1: A GPS receiver V works by observing the signals from a set of satellites. The relative delays of the signals s i(t) can be used to solve four equations which determine the 3-dimensional position L and the time offset δ of the receiver V . The clock offset δ adds a fourth unknown scalar.

A major part of improving anti-jam capabilities and increasing security is the development of a new military signal called M-Code. While transmitted in the same frequencies as the current system, M-Code is broadcast from a high spoofing signals. Multi-antenna anti-spoofing techniques mostly focus on detecting the spoofing threat and limited work has been done for spoofing mitigation. McDowell (2007) has proposed a mitigation approach that utilizes an antenna array. This method compares the estimated AOA of both authentic and spoofing PRNs after they are fully Sub-frame 4: provides ionospheric model parameters (in order to adjust for ionospheric refraction), UTC information (Universal Coordinate Time), part of the almanac, and indications whether the Anti-Spoofing, A/S, is activated or not (which transforms P code into the encrypted Y code).

The U.S. military has also deployed since 2004 their Selective Availability / Anti-Spoofing Module (SAASM) in the Defense Advanced GPS Receiver (DAGR). In demonstration videos the DAGR was shown to detect jamming and maintain its lock on the encrypted GPS signals during interference which caused civilian receivers to lose lock. Also GPS is experimenting with satellite based anti-spoofing for civil users with their recent Chimera authentication system. European Galileo satellites provide an open authentication service on the E1 signal and a commercial authentication service on the E6 signal.
