3-D face scanning could to unlock iPhone
Intent is to replace the Touch ID fingerprint scanner
SAN FRANCISCO — Apple is working on a feature that will let you unlock your iPhone using your face instead of a fingerprint.
For its redesigned iPhone, set to go on sale later this year, Apple is testing an improved security system that allows users to log in, authenticate payments, and launch secure apps by scanning their face, according to people familiar with the product. This is powered by a new 3-D sensor, added the people, who asked not to be identified discussing technology that’s still in development. The company is also testing eye scanning to augment the system, one of the people said.
The sensor’s speed and accuracy are focal points of the feature. It can scan a user’s face and unlock the iPhone within a few hundred milliseconds, the person said. It is designed to work even if the device is laying flat on a table, rather than just close up to the face. The feature is still being tested and may not appear with the new device. However, the intent is for it to replace the Touch ID fingerprint scanner, according to the person. An Apple spokesperson declined to comment.
In testing, the face unlock feature takes in more data points than a fingerprint scan, making it more secure than the Touch ID system, the person said. Apple introduced Touch ID in 2013 with the iPhone 5s for unlocking the phone and it added support for authenticating payments and logging into apps a year later.
Apple is not the first to use different forms of biometric authentication. In its latest phones, Samsung included iris scanners that let users unlock their phones and make payments by scanning their eyes. Samsung’s feature on its Galaxy S8 smartphone launched to poor reviews as users were able to trick the sensor with printed photocopies of a person’s eyes. Apple’s sensor has 3-D depth perception, which means the system is less likely to be duped by 2-D pictures.
The new iPhone’s debut this fall will mark the biggest upgrade in years to the company’s most important product.
Apple launched the iPhone 7 and iPhone 7 Plus last fall, focusing on camera and speed upgrades while using the same design as the previous iPhone 6s (which essentially added a pressure-sensitive screen to the 2014 iPhone 6’s design). The iPhone generates nearly two-thirds of Apple’s sales, and has become a central hub for products like the Apple Watch, Apple TV, and the new HomePod.
In addition to the face unlock feature, Apple is testing next-generation iPhone prototypes that include a dedicated chip for processing artificial intelligence tasks and screens that can display content at a higher frame rate.
The AI chip is internally called the Apple Neural Engine and would improve battery life by handling tasks like image recognition and typing suggestions, Bloomberg News reported in May.
The faster screens in testing are the same as the ProMotion displays in Apple’s latest iPad tablets, one of the people said.
For the device’s decade anniversary, Apple is also testing a new glass casing, steel edges, and a larger display that fits into a smaller overall body, Bloomberg News reported in April.
The new phone will have glass on both the front and back that curves at the edges.
Between the glass front and back is a stainless steel frame that houses power and volume controls, according to the report.
The front and back glass looks continuous because of how thin the steel surrounding frame is, people familiar with the device said.
