Apple is always slow to bring advanced technology to the iPhone, but when it does, it is a feature that is well received by the public.
With the iPhone X, Apple turned the public's attention to technology that has not made any mark on the phone for decades. It is the face recognition for unlock screen and mobile payments roles. Despite a big bet, but with Apples can be compensated properly, especially paving for the technology easier to use biometrics in the future more secure on smartphones.
Apple is turning facial recognition into "hot".
The Cupertino giants tend to slow down the "modern" features on the iPhone compared to other manufacturers. But each time, the company contributes to "polish" them and convince users that everything is now perfect to use. Someone can simply fool smartphone with a picture of the owner's face.
Apple named its Face ID feature, which will only be available on the iPhone X release in November, using sensors to simulate 3D faces. An infrared ray is projected onto the user's face with a microscope projector to sample around 30,000 points. All of them are recorded by the TrueDepth camera to form a complete face map that accurately collates previously stored data.
Apples with Face ID confirmed safe to test level 1 million new faces, there may have one overlapping cases. The technology behind it is not new. Anil Jain, a professor at the University of Michigan who studies bio-metrics and computer vision, emphasizes that this feature mimicked a method previously called a light structure to record facial expressions in three dimensions. Something that he used to identify objects in the 1980s.
The iPhone X is equipped with a special sensor system for exceptional accuracy.
However, Apple still have thoroughly researched to provide this form works well on smartphones. There are many ways to authenticate faces, but generally the accuracy depends on factors that affect real-time image quality, such as lighting conditions, the interval between capture and validation, or Outdoor elements include scarves, sunglasses.
Besides efforts to ensure the accuracy of Face ID, Apple also claims it works well even in the dark, glasses, hats or even for bearded users. This is the driving force for many companies to integrate face recognition on their phones or try to cram everything into the hardware, even using "simulator" like FaceTec.
"People still tend to copy what Apple does, and 3D has the effect of eliminating amateur imitators. You can not just take the picture and hope it does everything, "said by Kevin Bowyer, a professor of biology at Notre Dame University.
There will be many biometric technologies applied, or co-applied in the future.
Face ID is more difficult to imitate than fingerprint fingerprint identification because Apple uses a special sensor system to filter out many factors that serve the verification process.
In addition, future trends will add more features using bio-metric technology, such as the near-infrared light microscopy that already appears on Samsung phones. According to Jain, manufacturers can integrate all of face, iris and fingerprint sensors on a device for enhanced security. The cost of hardware will not be pushed too high. It helps the user have enough options when necessary online transactions, even if any party that requires authentication method 3 above.
