Apart from security and privacy measures, we take on our devices. The content that comes to us through their screens is eventually vulnerable to shoulder surfing. And is often the source of entertainment for overly interested peers.
However, third-party and in-built privacy screens have sought to manage and solve the problems to some extent. Apple seems to be preparing a solution that visually encrypts the display itself. This will make it impossible for unnecessary observers to find the actual screen content.
Shoulder surfing remains a regular practice among people who have little heed for user privacy. And usually engage in this wicked work, either for personal entertainment or to social engineer their way to someone’s confidentiality.
We tried to check this phenomenon with products such as HP’s Sure View display technology integrated with some of its laptops. And third-party privacy filters for many form-factor devices. Recently the company filed a patent that trails the user’s gaze as they run the device and visually encrypts content to protect it from undesirable observers. So, the users of Apple may not worry longer regarding this issue.
Apple’s “gaze-dependent display encryption” technology could come up in many devices of Apple in the future, PhoneArena reports. The devices such as Monitors, iPads, iPhones, the Apple Watch, other hardware, and anything with a display required for the tech to work.
Using the camera to detect and track the gaze of the user in addition to the special processing circuitry. The screen of the device can create visually encrypted displays when an onlooker is found. These frames comprise two regions. One that contains unchanged content for the intended user, based on their gaze and proximity from the camera. The second obscured region that displays used content through color altering, text scrambling, and image warping techniques.
When an onlooker’s gaze is far from the display, that content manipulation will take place vigorously, as “display content ceases to be visually encrypted”, the patent suggests. When they check out (intentionally or otherwise), the processing circuitry will start making visually encrypted frames, apparently obscure to the user.
The general concept potentially makes sure that information safely reaches its intended user. It is similar to Compubody Sock that laid down to achieve the same goal for many years. But in a simpler and low-tech fashion.
It needs to be determined that if Apple equips this encrypted display technology in its future products or plans to add this patent to its mounting pile of unused ones. The Face ID tech of the company could eventually advance this feature. Also, improving the user privacy of its devices furthermore. However, Apple‘s products with encrypted displays become more expensive in the future due to processing and financial costs involved in this technology.
