Apple has always held a special reverence for the privacy of its customers and tried to do everything to ensure their right to privacy. Biometrics, encryption – this, of course, is good, but neither one nor the other, unfortunately, does not protect against banal peeping. Therefore, Cupertino developed and patented a special technology for tracking the user’s gaze in order to display information on the screen only in the area where he is looking. This will avoid situations where someone outsider can peep into the screen and see what is not intended for his eyes.
The method of hiding information on the screen, described in a new patent by Apple, involves tracking eye movements in real time. The camera or special sensors will detect the direction of view, outline the visible area and display information only within it. For this, you can, for example, use the TrueDepth system, which underlies Face ID. As a result, the one who decides to peep into the screen, for example, over your shoulder, most likely does not fall into the same area because he will not be able to take the same position as the owner of the device and will not see sensitive data.
How to hide information on the iPhone screen
Of course, it would be foolish to draw a real circle with information on the screen, along the edges of which there would be a white or dark background. Therefore, the iPhone will draw and rebuild all the boundaries exclusively “in the mind”, and it is planned to mislead spies by demonstrating inaudible information that will be shown around the area where the user is looking and will change to real as he glides across the screen with a look. Ideally, it is planned to achieve such a speed of data updating so that the device owner himself does not notice fake information in principle and, if desired, could seamlessly move his eyes to any part of the screen.
It may seem that this kind of technology is incredibly difficult to implement and is unlikely to appear on Apple smartphones and tablets in the near future, but this is not entirely true. In fact, technologies like this have been used by different manufacturers for a long time. For example, BlackBerry smartphones use the Privacy Shade feature. It darkens the screen and highlights the information only in the area of the screen over which the user moves his finger. Not exactly what Apple wants to do, but the idea is pretty close. In addition, there are special protective glasses and films on the market that work on the principle of ATM screens, dimming the display when viewed from an angle.
How to protect yourself from spying on a smartphone
Apple itself already has the necessary developments, which allow, firstly, to track eye movements using TrueDepth sensors, and, secondly, to display information on certain areas of the screen. It will be possible to replace the information for those who are peeping with the help of augmented reality, which will simply impose some kind of confusion on the screen, if you look at it at an angle different from the angle at which the owner is looking at it. It turns out that the matter remains small – the implementation, but it can be the most difficult stage that can drag on for several years. And this is not to mention the fact that Apple, in principle, may not want to engage in the embodiment of this technology.
Is such a function necessary from a practical point of view? Well, if Apple can implement it exactly as described in the patent – with the display of fake information for smoothing – then, perhaps, yes. In this performance, it will certainly enjoy popularity not only among deputies, members of the board of directors and other high-ranking personalities, but also among ordinary users. At least, I would really like to know that no one is looking at me on the screen while I am conducting correspondence on work or with members of my family. But if Apple simply obscures the information, then it can, on the contrary, attract unnecessary attention from outsiders, which, in my opinion, is completely impossible to allow.
