• Acoustic Imaging Technology Reported to Replace Touch ID in Future iPhone Models

    Posted on February 24th, 2017 Echo Brown | 16 comments

    In its filing for “Acoustic imaging system architecture,” Apple proposes a method by which a conventional capacitive fingerprint sensor like Touch ID might be replaced by an array of acoustic transducers laid out beneath a device display or its protective housing.

    As described in some embodiments, the transducers in a first mode generate acoustic waves, or pulses, capable of propagating through a variety of substrates, including an iPhone’s coverglass. Operation, or driving, of the transducers is managed by a controller.

    The same transducer hardware then enters a second sensing mode to monitor reflections, attenuations, and diffractions to the acoustic waves caused by a foreign object in contact with the input-responsive substrate. Resulting scan data in the form of electrical signals is read by an onboard image resolver, which creates an approximated two-dimensional map.

    Applied to biometric recognition solutions, Apple’s acoustic imaging system might be configured to read a user’s fingerprint. According to the filing, ridges in a finger pad introduce an acoustic impedance mismatch that causes the mechanical waves generated by a transducer to reflect or diffract in a known manner.

    Like other biometric security solutions, the digital maps obtained by an acoustic imaging system are ultimately compared against a database of known assets to authenticate a user.

    Thanks to its design, the acoustic system can be installed practically anywhere in a device chassis, including directly under a display. Other potential points of integration include a screen’s perimeter or bezel, around buttons and in non-input areas of a housing, like a rear chassis. The latter coupling method would allow an example system to sample a user’s entire handprint.

    Indeed, in some cases the system might be configured to scan for particular body parts like a user’s ear or a skin pattern in order to determine how the device is being held. Depending on the implementation, an acoustic imaging system might also serve as a robust replacement for other legacy components like an iPhone’s proximity sensors.

    The patent application goes on to cover system details like ideal materials, transducer placement, controllers, drive chips, component layouts and more.

    • Nice read, I just passed this onto a friend who was doing a little research on that. And he just bought me lunch since I found it for him smile So let me rephrase that: Thank you for lunch!

    • I like what you guys are usually up too. This type of clever work and reporting! Keep up the great works guys I’ve you guys to our blogroll.

    • Good day! I know this is kinda off topic but I was wondering which blog platform are you using for this website? I’m getting fed up of WordPress because I’ve had issues with hackers and I’m looking at options for another platform. I would be great if you could point me in the direction of a good platform.

      With havin so much content and articles do you ever run into any issues of plagorism or copyright infringement? My site has a lot of unique content I’ve either written myself or outsourced but it looks like a lot of it is popping it up all over the web without my authorization. Do you know any techniques to help prevent content from being ripped off? I’d definitely appreciate it.

      You actually make it seem so easy with your presentation but I find this matter to be actually something which I think I would never understand. It seems too complex and extremely broad for me. I am looking forward for your next post, I’ll try to get the hang of it!

      Also I believe that mesothelioma cancer is a exceptional form of cancers that is often found in those people previously familiar with asbestos. Cancerous tissues form from the mesothelium, which is a safety lining that covers many of the body’s areas. These cells usually form from the lining with the lungs, tummy, or the sac that really encircles the heart. Thanks for revealing your ideas.

      I have seen that car insurance corporations know the automobiles which are liable to accidents along with other risks. In addition they know what form of cars are susceptible to higher risk and also the higher risk they’ve got the higher your premium rate. Understanding the easy basics of car insurance will allow you to choose the right form of insurance policy that can take care of the needs you have in case you happen to be involved in an accident. Thank you sharing the ideas on your blog.

      Hello there! Do you know if they make any plugins to safeguard against hackers? I’m kinda paranoid about losing everything I’ve worked hard on. Any recommendations?
