SATELLITE SECURITY-SEARCH SYSTEM Russian patent published in 2014 - IPC G08B25/00 B60R25/10 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to a satellite security-search system, which relates to systems for monitoring, tracking and controlling ground, water, sea or air-borne vehicles, which can be used for centralised monitoring of the state and location of serviced vehicles, remote control of units and assemblies of vehicles, and for searching for a vehicle and assisting a driver (owner) and passengers in emergency situations, for example, in case of vehicle theft or hijacking. A system for controlling a vehicle, facilitating search and identifying a hijacked/stolen vehicle in a central control unit 6 of a security/anti-theft subsystem 4 of a user system 1 includes a detachable identifier 21 of the security/anti-theft subsystem, exchange of output and input signals with the central control unit of which occurs in the infrared region based on an asymmetric coding algorithm with key length of more than 65 bytes, initiation of the detachable identifier is carried out with at least three secrete PIN codes, wherein the first PIN code is the working PIN code, the second PIN code is the alarm PIN code and the third PIN code is a service PIN code; PIN codes are entered into the detachable identifier using a key chain 22, also operating in the infrared region based on an asymmetric coding algorithm with a key length of more than 64 bytes. Correct entry of PIN codes should be confirmed by a brief light (sound) signal on the display of the key chain; the central control unit 6 of the security/anti-theft subsystem of the user system comprises a PIN code identification unit 23; the working PIN code is entered every time the identifier of the security/anti-theft subsystem of the user system is installed; the alarm PIN code is entered if the vehicle is hijacked and if the life and wellbeing of the user and passengers is under threat; the service PIN code is entered if there is need for authorised dismantling of the satellite security-search system. The detachable identifier of the security/anti-theft subsystem, key chain and PIN code identification unit are made using technologies which prevent unauthorised access, copying of information using devices and visual analysis of printed-circuit boards.

EFFECT: effective prevention of unauthorised access.
