Access Control Based on Bluetooth Technology

By: Olga

Nowadays on the market there are products that offer PC lock solutions- the idea is that you have a small "e-tablet" dongle in your hands and a receiver connected to USB port. It works like a car key.
By using your Bluetooth compatible mobile could do the same - just come in and Windows gets logged on - just step out - and it gets locked/hibernated. There are a few programs that provide such solution. They are: Wireless PC locks (GoldLantern, FrozenCPU, TrippLite), AccessAngel and Rohos Logon Key.
Listing each program's advantages and disadvantages would be time consuming thus I would like to take note of Rohos Logon Key software.
The Rohos Logon Key enables to use wireless devices equipped with BlueTooth for computer security. Your mobile phone or pocket PC, Palm, Nokia plays the role of your wireless key from your computer. It provides automatic Windows access approaching the computer with mobile phone. Computer will be protected with password, but you don't have to enter it manually, thus making life easier for lazybones J
When you step away from computer - Rohos Logon automatically locks the screen.

Using a generous 15-day trial period I was able to work out how the program works and I'm happy to share about it with you.

How it works:
Computer should have BlueTooth adapter.
The Rohos Logon saves your phone ID wirelessly
When the phone is near your computer, the access to it is open: automatic logon or it gets unlocked.
Also if you step away from computer, it will automatically be locked within 2 seconds.

* In comparison with AccessAngel you shouldn't install additional programs onto your computer, mobile phone or Pocket PC.

Here are some tips how to set up mobile or Pocket PC login:

First step:
First, you should install on you computer the Rohos Logon Key
In the main window screen open dialog box "Rohos Options"
In this dialog box for the type of device used as a USB key choose BlueTooth Phone/Pocket PC.

Second step:
Install BlueTooth adapter that is compatible with Windows
In the main window screen click "Set up USB flash drive". In the dialog box should appear the name of BlueTooth device, that was detected within the radius of coverage.
In the dialog box enter your Windows login password. If you haven't used a password so far, it's time to create one :0)
Now you should restart computer

! If you left your phone at home you might use usual password or emergency logon (that's offered by Rohos Logon).

Advantages:
No need to enter password manually for computer login - automatic Windows access
Password info is saved on computer encryptedly
Supports Windows Vista
Multi-logon feature
Personal version is just 25$, for corporate clients there is business version just for 39$.

Disadvantages:
BlueTooth operating radius may be up to 150 meters. Thus, auto-lock may work not as fast as a user would like it to.

The point is that wouldn't it make more sense to use the software solution that daily helps you rather than the ones that do not meet all your needs for easy access and PC security!?

Wireless PC locks - software solutions that provide just PC security (locks - unlocks computer). But for login you have to enter the password manually anyway. The cost from 13$ (better no PC lock than such one) up to 141$ (pretty expensive).

AccessAngel - for computer login you have to enter the password manually anyway. It requires Java 1.4, no trial version, cost 69 euro (private edition) is quiet high for a mere user, doesn't support Windows Vista (though supports 95,98,ME,2000, XP SP1+SP2).
