Apple's new patent exposure: acoustic imaging technology to replace Touch ID

According to foreign media reports, the U.S. patent and Trademark Office (USPTO) on Thursday passed an apple in August 2016 for the "acoustic imaging system architecture" patent, this patent describes a screen using acoustic transducer matrix instead of the Touch ID fingerprint sensor technology. There are rumors that Apple released this year, OLED iPhone Touch ID Home 8 will be replaced with a new key biological recognition technology, but what is this new technology what has not been determined, there may be new fingerprint identification technology, face recognition technology is also possible.

According to today's patent, apple removed the Home key, you can use acoustic imaging technology to achieve fingerprint recognition.

In the patent, apple referred to the acoustic transducer in the first mode can generate sound waves or pulses, and through a variety of substrates, such as iPhone screen glass. The operation and drive of the transducer can be realized by the controller.

Subsequently, the transducer hardware enters the second sensing mode to monitor the acoustic reflection, attenuation and diffraction of the object in contact with the input substrate. The scan data obtained will be read by the on-board imaging resolver in the form of an electrical signal and create a two-dimensional mapping.

Combined with biometric solutions, Apple's Sonic imaging system can be configured to read the user's fingerprint. The same as other biological security solutions, acoustic imaging system will be compared with the data obtained in the database content, complete verification. This system can be installed anywhere in the device, or directly under the screen. Other possible mounting locations include the perimeter or border of the screen, the buttons around it, and the non input areas of the housing, such as the rear shell. If installed in the rear shell position, you can sample the user's entire fingerprint.

The system can be configured to scan a portion of the user's body, such as the user's ear or skin. This kind of acoustic imaging system can replace many traditional sensors, such as distance sensors. At present, it is not clear whether the iPhone 8 will be equipped with such acoustic imaging technology. According to KGI securities analyst Guo Mingchi forecast, iPhone 8 will use face recognition technology to replace Touch ID. Apple iPhone 8 will be equipped with a revolutionary front 3D lens, face recognition function.
