GateKeeper, a Bluetooth wireless device worn on a lanyard, is the standard in military-grade encrypted access control. It protects data on your computer screen by reading your proximity, locking the computer as you leave it and, without passwords, turning the computer back on when you return. GateKeeper also provides the option to enable two-factor authentication to login. Its application for the corrections industry is obvious, as sensitive data accessed by correctional personnel needs to be secured from compromise. GateKeeper can do that.
