Facial recognition as a kind of security mechanism, thermal imaging camera has been widely used in more and more mobile phones. The technology through the analysis of the biometric facial information gathering user, and then with the database (set is created when the) compare the facial features of the model, and use that to unlock the phone. Is expected in 2022, facial recognition in personal and business application scenarios of the size of the market will exceed $7.7 billion. Although facial recognition technology can help to confirm the user's identity, but people also do on caused by the technology of privacy concerns.
The working principle of face recognition
Although facial recognition technology in the interactive kiosk price concrete implementation will have differences, but the basic principle is the same. First of all, users face image as a benchmark. Software will identify the basic shape of the face, including the distance between the eyes and the distance between the forehead to the chin, and any other can be used as a distinguishing characteristic of face sign. Then the user's face data will be saved in the form of mathematical models in the system. Finally, when a user use facial recognition function, cell phone will analyze the user's facial features, and save the maths model of the system. If the two match, the phone will be unlocked. Some mobile phone will keep track of any attempt to unlock the phone facial data, and save it in the cloud (apple devices) or local storage (android).
The advantage of face recognition
The biggest advantage of face recognition is easy temperature check kiosk to use. Users only need to pick up the phone, front camera will quickly scanned for facial and unlock the phone, no need to enter the password or PIN. For many people, they just want device has a simple and easy to use safety protection mechanism, and facial recognition technology to satisfy this requirement. Because of complex code and password are hard to remember, so easy to use as facial recognition, and weak passwords or codes will be easily crack, and greatly reduce the security of the mobile phone.
The safety of face recognition
Unfortunately, the application of new technology, often interactive whiteboard prices accompanied by the emergence of new vulnerabilities. At the university of Toronto in the previous studies disclose the major defect of facial recognition technology. One of the experiments showed that only the corner parts of the pixels to modify, will lead to phone unable to properly identify facial information of users. In another experiment, in the of 110 mobile phones being measured, only with a photo of the user can unlock the 42. More according to the report, even if the user is sleeping, the facial information can also be used to unlock the phone. These findings suggest that as facial recognition technology of mobile security mechanism, can on the user's unconscious or the absence of notice be bypassed.
