Keep Confidential Information Private With a Privacy Filter

We are constantly using our computers in school and work, and in this digital age, we’ve become totally dependent on getting our information digitally. However, some of this information is private. Though using hardcore passwords and state of the art encryption goes a long way in protecting against leaked confidential information (One, 2020), there’s no way that would protect you from prying eyes.

Yes, people can simply look over your shoulder and see whatever is displayed on your screen, and this can have very impactful consequences especially if you are constantly handling sensitive data like employees’ payrolls. The worst part is, most people neglect to protect their personal computers against such a threat.

And that is where privacy filters come in. They’re a safe way to prevent visual hacking and keep your screen to yourself.

What’s a privacy filter?

A privacy filter refers to a panel placed over a display, used to protect private data on the screen. It makes it almost impossible for someone to see the screen without facing it dead on.

These filters are low-tech, consisting of a polarized plastic sheet. Polarization functions as an optical filter that blocks out light from certain angles. In this case, all angles except the one right in front of the screen. This is the same technology used for polarized sunglasses and some types of camera lenses (Windows Report | Error-free Tech Life, 2020).

How privacy filters work

We can look at blinds for example. Think of your window with vertical blinds. When open, these blinds enable you to see the outside if you are directly in front of them, however, when you start moving to the side, the surface area of these blinds start blocking your view making it impossible to see through.

Privacy filters work the same way but on a much smaller scale, with a typical filter containing thousands of polarized blinds. The best of these filters have very thin blinds which then allows more light to pass through hence giving you a better viewing experience.

Though the models of these filters differ, most of them usually start blocking the view from your screen at about a 30-degree angle. This is to give you enough headroom so you can still see your screen when tilting your head. However, the screen is usually blacked out at about a 60-degree angle.

What to look for in a privacy filter

Before getting one of these filters, you need to know exactly what you’re looking for to get value for your money. Here are some quick tips:

Application method

You need to ensure that the filter you go for can be applied and reapplied without needing any special attention. How these filters are placed on the screen varies from one model to another so get one that uses reusable micro-suction strips that won’t leave any sticky, unpleasant residue when you take them off.

Size

Since these privacy filters are designed for computers of all shapes and sizes, you may want to know the size of your monitor before opening your wallet.

Warranty

You will also be better off going for a provider that offers a warranty period on these filters. That way you can be sure that you are getting a product that will last.

Reflective color

Standard privacy filters will look black when viewed from an angle. But you can also get filters that give off a golden color when you’re not looking at the screen directly. The golden accent will make the screen more reflective hence you won’t get a dim screen when using it. However, such reflective accents can be an eyesore if you’re mostly using your screen from outdoors.

Remember, our digital devices have made their way up our priority lists and we really can’t do without them. They store all our important information and assist us in browsing the internet as well. These devices are also crucial when it comes to working, running our business and even doing our homework. If you normally use your screen in the presence of people such as fellow employees or students, you may really want to install these privacy filters to keep your information safe.
