There is a possibility that the next-generation iPhone will be equipped with a built-in screen’Touch ID’. Since 2017, Apple has been introducing face recognition’Face ID’ instead of Touch ID, which is a fingerprint recognition method, but rumors related to Touch ID continue to emerge. In particular, as the use of masks became more common after Corona 19, as voices complaining of discomfort to Face ID increased, the rumors of the return of Touch ID are getting stronger.
29th (local time) <월스트리트저널>Cited two former Apple employees and reported that Apple is working on a fingerprint recognition technology with built-in screens, and is considering installing both Touch ID and Face ID in one device. It is known that the technology Apple is considering is an optical type rather than an ultrasonic type installed in Samsung’s Galaxy S21.
The iPhone gatekeeper has changed from Touch ID to Face ID. Apple first introduced Face ID instead of Touch ID in’iPhone X’in 2017. Since then, except for the’iPhone SE 2nd generation’ released last year, all of them have Face ID installed. Considering that the 2nd generation of iPhone SE recycled the’iPhone 8’form factor, all newly designed iPhones came out with Face IDs instead of Touch IDs. In the iPad, since 2018, the introduction of Face ID has been spreading around the’Pro’ product line.
However, as the limitations of the face recognition angle and the recognition rate falling in a strong lighting environment were pointed out as disadvantages of Face ID, the voice of searching for a touch ID again increased. In particular, since the face recognition function did not work properly while wearing a mask, weight is being put on the theory of returning Touch ID after the Corona 19 incident. In addition, in the Android camp, the built-in screen fingerprint recognition method is centered on flagship smartphones.
This is not the first time we have heard about the built-in touch ID. It is known that in December 2018, Apple applied for a new patent incorporating Touch ID and Face ID to the European Patent Office (EPO). TF International Securities analyst Guo Ming-chi, famous for Apple’s product prediction, also predicted that Face ID and next-generation Touch ID will be installed on the iPhone in 2021. Last year, Apple applied for a patent on fingerprint recognition with an embedded optical screen to the US Patent Office.

this time <월스트리트저널> Reports also mention that the Touch ID technology Apple is researching is optical. According to all Apple employees cited in the article, the optical touch ID is expected to be more reliable than the existing ultrasonic technology. The ultrasonic sensor is a method of recognizing fingerprints by emitting sound that humans cannot hear, and recognizes the height of the actual fingerprint and extracts the fingerprint through the cycle of the emitted ultrasonic waves returning. In general, it is known that ultrasonic sensors have higher security than optical, which is a method of recognizing images. It is believed that Apple is working on a solution that is more advanced than the existing optical sensor with built-in screen that simply recognizes a two-dimensional fingerprint image.
The employee said that if Apple does not meet the current TouchID security level, it will not adopt optical fingerprint recognition.
