Many computer users try very hard to find the perfect software to protect their privacy and the security of their information by setting up encrypted drives, biometric authentication, or similar technological measures. What many people forget to do is set up a simple and very effective privacy protection - the monitor screen filter.
It is not uncommon to sit in a cafe or on the airplane and see a busy businessman or a lawyer busily staring at their laptop screen. Unfortunately, what is also uncommon is the fact that you can easily read what is on their screen, especially with the modern high-contrast laptop screens. I am not aware of statistics but there must be instances of confidential legal or business information being lost due to “shoulder surfing” while it is displayed on somebody’s screen and seen by others.
There is really no software solution to this. Fortunately, there is a very simple and relatively inexpensive tool that all users who display sensitive information on their laptop (or on their desktop, if they share office space with other people) should consider - screen privacy filter. This may be the best $50-$100 spend on information security and privacy.
