Recently, fingerprint recognition solutions giant Synaptics has announced an important message: the first optical fingerprint sensor under the screen is expected to achieve mass production by the end of this year. When it comes to whether ultrasonic fingerprints and live detection fingerprints are safer than other options, Synaptics says these technologies do make the sensor safe than any sensor without any protection, but only protects one of the fake fingerprints.In fact, Synaptics said that the majority of notebook computers on the fingerprint identification solution is not safe, personal information security depends largely on the encryption method between the fingerprint sensor and PC exchange information. In the sensor that false fingerprints break, Synaptics also add thermal sensors. In addition, there is a enhanced Match-in-Sensor solution that does not require the fingerprint image to be transmitted to the sensor itself. Synaptics believes that these technologies are credible and will continue to enhance the fingerprint sensor solution, making Synaptics solutions the market"s most secure solution. At the same time, Synaptics demonstrated finger model produced by use of conductive paper, which is easy to break the iPhone 7, a laptop computer fingerprint identification system. Synaptics thinks anti-fingerprint technology does not depend on photodiodes and sensors, and believes the best way to prevent false fingerprints is to use machine learning.In the mobile phone manufacturers, with the hot speculation of full-screen mobile phone concept, there is a trend from capacitance to optical fingerprint sensor.
