Security Exhibition Network Technology News Apple hopes to improve the security of FaceID and other vision-based biometric systems by using unique and difficult-to-replicate vein patterns that reside under the skin to eliminate the so-called "twin problem." Biometric security systems such as FaceID and TouchID provide protection for user data in relatively simple and understandable packaging. This is also a very simple system to use, because users do not need to remember passwords or codes, because their face or fingerprint is actually their account credentials.
Although the security is very good, they still have shortcomings in many aspects. For example, the false positive rate is very small. In terms of face recognition, the false positive rate is only one in a million. Another problem is that people can create highly complex masks to fool FaceID. Normally, this method is far beyond the ability of normal people. Finally, there is a "twin problem". Facial recognition systems like FaceID can provide access to people who look extremely similar, such as twins or family members.
In the U.S. Patent and Trademark Office on Tuesday granted Apple a patent entitled "Vein Matching for Difficult Biometric Authentication Cases," Apple proposed that the vein can be used as an identifier. Although facial features are easy to replicate, the pattern of veins varies greatly among individuals, even among twins. Because they are also under the skin and occupy a three-dimensional space, it is extremely difficult to create a fake face that takes into account the structure of the veins without the extreme cooperation of the subject or the medically invasive operation.
The Apple patent shows that the system includes the use of subcutaneous imaging technology to create a 3D map of the user's veins. For example, the infrared sensor in the camera captures flood and spot patterns from an infrared illuminator that illuminates the user's face. This is somewhat similar to the current working method of FaceID, which emits infrared rays in the form of a pattern on the user’s face and is read by an imaging device, but Apple’s patent is specifically to detect blood vessels instead of appearance. Like other biometric methods, the system must determine Whether the scanned data is close enough to the previous version. If the match is close enough, the system will effectively confirm that the user is authorized and grant access. Apple submits a large number of patent applications every week, but there is no guarantee that the idea will appear in future products or services.
