When business users are away from their physically secure office environment, they put valuable information at risk by exposing it on their laptop computer screen for others nearby to view. Industrial spies are known to be in airports, train stations, restaurants and other public areas where they might glimse valuable client or industry specific information. Some companies encourage their employees to avoid working while waiting at any of these locations for this very reason, resulting in loss of productivity. Other companies are aware of the risk to their information, but nonetheless allow their employees to work in these public areas because they cannot afford to lose productivity during the long period employees may spend at an airport or train station. The Secure Laptop Viewing System solves this problem with existing technology and hardware. This makes the solution very inexpensive and easy to use. A user would start a graphic polarizing software program on their laptop, enter the serial number from their specially polarized glasses, and then put on the glasses. They would then be the only ones to be able to see what is on their computer screen, through the special glasses. If an individual already had perscription glasses, they could utilize a "clip-on" version of the optics. This would increase security surrounding valuable client and industry specific information and would allow employees to work in busy areas such as airports, train stations and restaurants without worrying about who is looking over their shoulder. Laptop LCDs may be configured to present polarized light through software drivers in a number of ways. This would be optically at the LCD via the way the liquid crystals are activated into displaying light. Or this could be through translation software that would sit at a software driver level and translate an Operating System's messages to the display and modify them so they could be presented to appear polarized. Either way this optical presentation would be unique based on a mathematical formula so that the odds are remote that even someone sitting next to you with the same special glasses could not view your laptop screen. Serial numbers on the glasses would be required as input to the software on the laptop upon starting to determine how to visually present your Operating System to the particular glasses you are wearing.
