Why it matters: Regardless of the security and privacy measures we take on our devices, the content reaching us through their screens is ultimately susceptible to shoulder surfing and is often the source of amusement for overly inquisitive peers. Although third-party and in-built privacy screens have tried to address the problem and succeeded to some extent, Apple seems to be developing a solution that visually encrypts the display itself to make it impossible for unwanted observers to figure out the actual screen content.

Shoulder surfing remains a common practice among folk who have little regard for user privacy and often engage in this unethical activity, either for personal amusement or to social engineer their way to someone's sensitive information.
Apple users, however, might not have to worry long about this problem as the company recently filed for a patent that tracks the user's gaze as they operate the device and visually encrypts content to protect it from unwanted observers.

PhoneArena reports that Apple's 'gaze-dependent display encryption' technology could appear in multiple Apple devices in the future, including iPhones, iPads, monitors, the Apple Watch - basically anything with a display and other hardware required for the tech to function.

Using the camera to identify and track the user's gaze, along with special processing circuitry, the device's screen can generate visually encrypted frames when an onlooker is detected.
It remains to be seen if Apple implements this technology in its future products or simply decides to add this patent to its ever-growing pile of unused ones.

iPhone Patent Reveals ‘Gaze-Dependent Display Encryption’

Using the device’s front-facing camera, it could track its owner’s eyes to figure out where he/she may be looking on the screen. In that area, the device would display the real contents there. But others looking at the screen would show fake information as a privacy measure.

The fake content could even look similar to the real content, but be unreadable. The TrueDepth camera on the iPhone X and later already have eye tracking for its Face ID Attention Awareness feature.
