The popular 'Lojak' car tracking system has similar civil liberties issues. I understand that the car owner has no control over it's activation, can't disable it, and there is no indication that it is in operation.Apparently all the "authorities" need to turn it on is the VIN.
Lojak, like uses a pager frequency to activate the transponder. It is easy and inexpensive to build a low-power de-activating transmitter, operated in or near the car, to jam the pager receiver and prevent the unit's operation. --Steve PGP mail preferred, see http://www.pgp.com and http://web.mit.edu/network/pgp.html RSA PGP Fingerprint: FE 90 1A 95 9D EA 8D 61 81 2E CC A9 A4 4A FB A9 --------------------------------------------------------------------- Steve Schear (N7ZEZ) | Internet: azur@netcom.com 7075 West Gowan Road | Voice: 1-702-658-2654 Suite 2148 | Fax: 1-702-658-2673 Las Vegas, NV 89129 | economic and crypto dissident --------------------------------------------------------------------- The push by western governments for financial transparency and banning unrestricted use of cryptography is blatent politicial tyranny.
