Screen Keeper (Computer Monitor Privacy Protector)

The Screen Keeper is a personal, automated, computer privacy system, which blanks and locks your computer screen when you are away from your system. While most other system systems lock your computer based on the amount of time since the last activity, the Screen Keeper system is based on proximity. Walk away from your system and it will automatically blank the screen and lock out input. Come back and it automatically unlocks and restores your computer screen!

The Screen Keeper system comes with a dongle receiver, which plugs into your computer's USB port. A small, low-power RF transmitter can be attached to your clothing or put into your pocket. Whenever you are within a few meters of your system it will be active and you can use it normally. Whenever, the transmitter moves to 4-9 meters away, your screen is automatically blanked and the system locked to prevent tampering.

The distance at which the system is locked and blanked is adjustable over three ranges (short, middle, long). The software also allows you to let the monitor go into power-saving standby mode whenever you are away for the specified amount of time. The transmitter device will also go into power-saving standby mode whenever you are away for a while. To reset the device, simply turn it off, then back on and it will be ready to activate your system whenever you are within the appropriate range.

The single CR2025 battery in the transmitter device will last about a year, based on a standard 5-days/week, 8-hours/day work schedule. For best results, the receiver dongle should be placed on top of the desk, next to the keyboard, which may require the use of a USB extension cable.

Potential problem in Win8

Pros: Easy to use, small, pretty much what I was looking for. Though, wish it worked off my phone's bluetooth for a proximity data.

Cons: In Windows 7 the screenkeeper can be defeated in some cases. Also, the top lid unglued from being in my pocket (moist and sweaty environment), now need to put it on crazy glue.

For win7, if you choose to CTRL+ALT+DEL, you will get a choice to log off. If you have something open but not saved, it might unload the screen keeper from memory and then the screen would go to the desktop to ask you if you want to save it before logging off. Then you can cancel "log off" and use desktop without screenkeeper at all. This depends if the system will remove screenkeeper from memory before the program that has something unsaved. But in win7, it is potentially defeatable. Thus, it is just a toy.

Strictly a privacy keeper.. not security

Pros: Screen saver when you leave..
Require password if you don't have the device with you.

Cons: Logs back in when the device gets closer to computer.
It's privacy for your screen, when you are away.

not what I was looking for..
I was looking for extra security guizmo, that would still require password. But would make sure it locks computer when you leave. A physical device that you'd need on top of the basic usual password. Making a workstation 2-factor authentication station.

Screen Flicker

  • nhibbard,

Pros: Works as listed with different distances and a screen lock.

Cons: Requires software with minimal features. Devices causes the screen to flicker at times, more so when placed in a pocket rather than around the neck.

I would tentatively recommend to anyone looking to lock their screen for business reasons when they walk away. There are password prompts on startup and when the device is not in proximity to allow for forgetting the device at home. I do wish for an update that is plug and play without installed software.
