The iPhone 8 with Touch ID is not safe because Apple wants to remove the Home button from its future smartphone model, but it could find an ingenious way to keep it. A new patent registered to those from Cupertino describes a new technology that would allow fingerprint scanning in the iPhone 8 using a series of acoustic sensors mounted under the screen.
According to this technology, the respective sensors would be placed at various points under the screen and based on acoustic waves, or pulses, that propagate under the screen, would allow fingerprints to be scanned in the iPhone 8. Apple should implement sensors under the iPhone 8 screen that generate these waves, but also others to capture them, to be able to scan the fingerprint.
According to the patent, the iPhone 8 could distinguish a fingerprint based on mismatches in acoustic impedance. The iPhone 8 would analyze all the data using a special sensor, and according to the patent, Apple could configure this sensor to be able to identify various parts of the human body, depending on the typical needs.
iPhone 8 – here's how Touch ID could transform
Considering the advanced technology behind these sensors, the patent also tells us that the iPhone 8 could remain without proximity sensors. Apple could use the acoustic ones to figure out how far the user's head is from the iPhone 8 and could block or unlock the screen when making phone calls.
Considering that we are talking about acoustic sensors, the patent tells us that they could be mounted anywhere in the iPhone 8 case for scans. Whether we are talking about the implementation directly under the iPhone 8 screen, or under the edges of the front panel, the final result will be the same, and the fingerprints will be read, theoretically, as accurately as in the case of a fingerprint reader.
"An acoustic imaging system includes multiple transducers disposed to circumscribe a portion of substrate. An acoustic imaging system also includes a controller and an image resolver. The transducers convert electrical signals into mechanical energy and/or mechanical energy into electrical signals."
Basically, considering the way the iPhone 8 is thought, the Apple company is looking for ways to keep Touch ID while giving up the fingerprint reader. Of course, this achievement is not easy, but Apple has everything it needs to give us iPhone 8 and Touch ID.
