How a Fingerprint Reader Works

!±8± How a Fingerprint Reader Works

Has this ever happened to you? You haven't been to a website in a few weeks and you just can't remember the password and now you have to go back through your email and fish it out. Or, do you do this major no no of security? Use the same username and password for every website and application you can.

It's time you tried a password storing finger print reader. Basically all consumer finger print readers work the same; you install the software and connect the fingerprint device. You then install the fingerprint reader into an available USB port, scan your finger (usually the right index finger), and now as you surf the web the software will ask you if you want to store the user id and password associated with that site.

Now the fun part, once you visit that site again in the future all you need to do is place your finger on the reader and it fills in those pesky user id and password fields for you. No need to ever forget or use the same password again.

So how does this all work?

Before we start it's good to know that this technology exists because we all have our own uniquely identifiable piece of information, our finger prints. While our forerunners did not develop this adaptation for password protection, more for gripping and holding, it's a nice side effect. Since each set of fingerprints in developed in its own way through thousands if not millions of environmental factors there is almost no chance that anyone has, has ever had or will ever had the same fingerprint as you; even if you are an identical twin.

So now the fingerprint reader just has to scan your finger and make sure all the ridges match, sounds easy right? Well, it does take a quite of bit of technology to actually make it work. First the scanner uses either an optical or capacitance scanner to take a "picture" of your finger using either light or electricity respectably.

They then "read" if what it's looking at is a ridge or valley and uses your computers processing power to compare the captured fingerprint with the fingerprints on file, from setup, in your system. They do this by using very complex algorithms and focusing in on the very fine parts of your actual fingerprint and comparing specific features called minutiae.

The scanner doesn't take your whole fingerprint into account when making a match; it just has to find some parts that match both the minutiae and the record of your print on file. Once the threshold of matches is reached voila you have access to that password protected page you wanted and you didn't even have to think about it.

What's The Scoop On The Gunvault GV1000D-DLX Mini Vault Deluxe Gun Safe?

!±8± What's The Scoop On The Gunvault GV1000D-DLX Mini Vault Deluxe Gun Safe?

The Gunvault GV1000D-DLX Mini Vault Deluxe Gun Safe is another of the highest-rated gun safes on the market. It can either use Biometric (fingerprint recognition) or digital code input for access. It comes with a number of safety features which I will cover later in the review. It is easily mountable and solidly built, and Gunvault is one of the premier names in the world of gun safes, so you know you're getting a quality product.

-Dimensions - 8.1 x 4.9 x 12?
-Weight - 9 lbs
-Mountable - Yes
-Powered by - AA batteries or an included AC adapter for backup

Gunvault GV1000D-DLX - Is It Safe?

The Gunvault GV1000D-DLX is a strongly built gun safe; the exterior is constructed of 16-gauge steel and the lock mechanism is very sturdy. While I would highly suggest bolting this gun safe down, it also has a feature that will sound an alarm if it is picked up and in locked mode. Like some of the other gun safes by Gunvault, the GV100D-DLX will completely lock out an intruder after a certain number of failed tries, and it will record all attempts at tampering with the safe itself.

The key input pad is, what Gunvault has patented as a "No-Eyes Keypad", meaning you can easily open it even in complete darkness. The safe does have an audio feedback feature to confirm correct key entries, but this can be disabled. These two features are great to have in the case of an intruder in your home. When it comes to choosing a key code for access, you can chose any combination of the available keys, including even pressing multiple keys at the same time. It would be impossible for someone to guess the combination, as there are a possible 12 million(!) combinations that you can choose from.

The biometric access can store up to 30 different sets of imprints for access. You probably will never need to give that many people access to your gun safe, but it's nice to be able to let your wife, older children, or other residents of your home have reliable access to your firearm or belongings in the case that it's needed. Gunvault has also developed a technology that will continually update and refine the fingerprint templates recorded to make sure that your prints are always recognized.

All in all, the Guvault GV100D-DLX Mini Vault Deluxe is a great product that you can't really go wrong with. If you're on the market for a small, discrete gun safe for storage of your firearm of other personal belongings, this is a great one at a very affordable price.

What we liked about the Gunvault GV100D-DLX:

-Very secure safe; fingerprint recognition always updates itself
-Very affordable for such a secure safe
-Easily accessible even in complete darkness

What we didn't like:

-Takes batteries to operate (although AC adapter is included)
-Needs a little bit of practice to be able to open quickly (but it really does open fast)
