Apple engineers are constantly patenting technologies that at some point could end up in our future iDevices, and the most recent of them describes a technology by which iDevices would lock/unlock themselves by analyzing the face of the user. uses. The system thought by Apple is presented as being useful because some users avoid setting a security code for terminals because they could quickly forget it, and this system would block the device when the user was no longer found by the front camera and would unlock it at the moment which the user would have found by it.
For instance, consider that the device is initially unlocked. In that state, a built-in camera captures one or more images, and the images are then analyzed to determine whether a user's face is present therein. If a user's face is not present in the images captured over a predetermined amount of time, the device automatically locks. Thus, the device is automatically locked when it determines that no user is currently using the device without having to wait for an idle timer to expire or a manual switch off by the user.
The camera could work together with the accelerometer, for example, and when the terminal was moved, the camera would be activated and when the user's face was detected, the device could be unlocked. Although an automatic system is also used by Google, the implementation of Apple's requires that everything be automatic, while with Android OS the user must select the use of the system at each step. What Apple proposes is interesting, it deserves to be taken into account, but it remains to be seen if it will be useful in any way and if it will end up in iDevices.
