There are additional ways you can restrict access to your PC and monitor what�s going on. Most of these methods are fairly inexpensive and easy enough to install and use so that you can do them yourself. For instance, you can install some type of biometric device, such as a fingerprint scanner or voice recognition system that will permit a limited number of authorized users and refuse access to those who are unauthorized. You can buy the U.are.U fingerprint scanner by digitalPersona at most computer stores. Similarly, you can by SAFtylatch by SAFlink, a voice security program that will only permit use of the PC after the user�s voiceprint matches one in the program�s database. You can install Watchdog software from Charles River Media and get a log of all the activity that takes place on the PC
