Touch ID is Apple’s iPhone and iPad biometric fingerprint recognition system, used to verify Apple Pay payments and to supplement device passcodes and in-app passwords. This has First introduced in 2013, Touch ID is built into the Home button of the iPhone 5s and later, and ipad
Touch ID is built around a capacitive touch sensor that can read and analyze sub-epidermal skin layers to identify each person’s unique fingerprint to make tasks like downloading apps and unlocking iOS devices more convenient.
Apple’s intellectual property has clearly indicated that the next generation of Touch ID is destined for the iPhone. Apple has reportedly decided to use its own authentic algorithm combined with Privaris glass identification technology to redesign a new fingerprint ID solution, according to industry sources. Apple acquired Privaris back in June 2015
Recent reports said that “Apple’s in-house developed fingerprint ID solution will be fabricated at TSMC’s 12-inch line using 65nm process technology, said adding that production for the new OLED iPhone is unlikely to start until September due to the redesigned fingerprint ID solution..
The upcoming OLED iPhone will also feature a built-in fingerprint sensor device, instead of traditional capacitive touch technology, and use biometric authentication systems such as ultrasound, the sources indicated.
One of the more contentious iPhone 8 rumors we’ve seen recently is the claim that with the removal of the Home button, Apple will ditch its Touch ID fingerprint recognition technology and replace it with another form of bio-recognition hardware.
While several possible alternatives have been put forward – such as iris scanning, facial recognition. On the other hand, it’s possible that Apple plans to retain a fingerprint identification system in the context of a wider technology which doesn’t rely on Touch ID as it is currently understood.

Detail description

The acoustic imaging system is configured to resolve an image of a user fingerprint when the user touches he display. The acoustic imaging system operate re by generating acoustic wave that propagate through an external surface of the display and thereafter monitoring reflection attenuation and diffraction to those acoustic wave caused by the users fingerprint after the user touches the display and after a fingerprint image is resolved by the system compare too resolved image –or information derived there from if the processor determines the match , the processor informs the electronic device , after which the electronic cab perform a restricted access task , such as showing private .personal, or confidential information on the display .

A new Apple patent application published on 2 march 2017 .The patent is called “Acoustic imaging system architecture, application no (20170053151)” and describes a method by which a conventional capacitive sensor like Touch ID is replaced by an array of acoustic transducers laid out beneath an iPhone display or in its protective housing
The U.S. Patent and Trademark Office, newly granted U.S. Patent No. 9,582,102 describes an “Electronic device including finger biometric sensor carried by a touch display and related methods.” While the current implementation of Touch ID works using a dedicated fingerprint reader and capacitive ring built into the home button, the patent suggests that future fingerprint scanning could be done on the display itself
Titled “Interactive display panel with IR diodes patent no (US 20150364107 A1 )”, is the another patent – details a touch display that uses specifically microLED-sensing technology, rather than the traditional active matrix hardware utilized by most consumer Smartphone and tablets
Apple bought from the closed biometric security firm in June 2015 that included dozens of patents relating to fingerprint and touchscreen technology, including – in at least one example – the ability to use a touchscreen and fingerprint reader at the same time
Fingerprint recognition using entire iPhone display
Apple is considering a future without a physical home button on its iPhones have been bolstered by a patent granted to the company —one that could allow users to authenticate their fingerprint by touching anywhere on the screen.
The method used to read fingerprints involves the use of multiple layers to make the screen, including one display layer, at least one transparent conductive layer, and another for fingerprint reading. This biometric sensor could include an interconnect layer with “transparent conductive traces,” and a “transparent dielectric layer” between the sensing and interconnect layers.
All of these layers would be sandwiched between the display layer at the bottom of the stack and a top “transparent dielectric cover,” which the patent suggests could be glass. Though it could be limited to a specific area of the display, it is possible for the sensing area to cover the viewable display area, making the entire screen into a single cohesive fingerprint reader.

Fingerprint Sensing MicroLED Displays Sans Touch ID

The U.S. Patent and Trademark Office granted Apple a patent that describes a display capable of reading a user’s fingerprint without a dedicated Touch ID sensor. The patent is interesting given current rumors swirling around the iPhone 8, which is expected to do away with the home button and integrate Touch ID directly into the display, but perhaps more noteworthy is the patent IP’s re-assignment from LuxVue, a little-known company acquired by Apple in 2014 that developed low-power microLED-based displays.

The patent describes a couple of embodiments for the technology, including a microLED display with a higher density of interactive pixels in certain areas of the screen, such as where a virtual home button may be located. Alternatively, said pixels may ramify throughout the display in sufficient number as to make fingerprint identification on any portion of the screen a possibility.

Redesigned Fingerprint ID

Apple is set to feature its own in-house developed integrated fingerprint ID technology in the OLED version of its next iPhone, according to a new report out on 03-03 2017.
Apple’s upcoming “iPhone 8” is expected to feature a virtual home button embedded in the display, but questions persist over the role of Touch ID in such a radical redesign as conflicting reports from analysts, rumors of biometric alternatives.

Finally, the report goes on to claim that the tenth-anniversary edition iPhone will use “biometric authentication systems such as ultrasound”, adding to the possible mix of facial recognition and iris scanning technologies also rumored to be in the works. other features more widely expected for the “iPhone 8” include some form of wireless charging and a glass body.
