In recent years, mobile phones have undergone several transformations. In a first phase, when the prevalent use function was that of voice communication, manufacturers aimed at portability thanks to miniaturization technologies. Then, with the massification of the web and apps, the function of use shifted towards navigation and games, and this required brighter screens and larger dimensions. This evolution has been supported by progress in the field of microprocessors: increasingly compact, powerful and specialized (currently in a smartphone next to the CPU, there is also a GPU, which is responsible for graphic calculations). Today the most important part of a smartphone is becoming the camera (or rather the cameras) so much so that it would be more correct to talk about a smart camera or a "computer with sight".
The launches of the iPhone The new fetishes of Apple and Canada Phone Number Google are a concentration of technologies, the most advanced of which serve to improve the camera, which becomes the central element of the device. No longer just a component that serves to faithfully reproduce reality, but also to improve security and enable augmented reality functions. Camera as a security device In the iPhone All this, which Apple calls Face ID, is possible thanks to a system, called TrueDepth Camera System, composed of a dot projector, an infrared camera and an illuminator, coordinated by the A11 Bionic processor.
This three-dimensional footprint map is encrypted and stored in the "Secure Enclave". When the user stares at the device, from any position, the A11 Bionic chip (capable of performing up to 600 billion operations per second) compares the map with the image returned by the camera to verify the correspondence. Day after day, the machine learning algorithms processed by the chip are also able to record changes in the face and update the model. The system would be more secure than the one implemented by Samsung on the Galaxy S8, with the possibility of only one error in 1,000,000 attempts.
