The capacitive touch screen works by utilizing current induction of a human body, generally, the capacitive touch screen is a four-layer composite glass screen, the inner surface and the interlayer of the glass screen are respectively coated with a layer of Indium Tin Oxide (ITO), the outermost layer is a thin silica glass protective layer, the ITO coating of the interlayer is used as a working surface, and four electrodes are led out from four corners of the coating. The inner ITO layer is a shielding layer for ensuring a good working environment. When a finger touches, due to the action of the human body's electric field, the user and the touch screen surface form a coupling capacitance, which is a direct conductor for high frequency currents, so that the finger draws a small current from the contact point.

Fingerprint identification is to transmit a trace amount of radio frequency signals through a sensor, penetrate through the epidermal layer of a finger to detect the texture of the inner layer, and obtain a fingerprint image. When the radio frequency signal penetrates through the skin of a person, the human body can generate chemical reaction, different substances contact different chemical reactions generated by the radio frequency signal to return different signals, so that a fingerprint image is obtained, the passing rate of the fingerprint image for difficult finger identification such as dry fingers can reach 99%, and the anti-counterfeiting fingerprint capability is strong. The fingerprint identification principle of the radio frequency signal only reacts on human dermis skin, so that the problem of artificial fingerprints is fundamentally solved, and the radio frequency signal has a wide temperature zone and is suitable for cold or hot areas. In addition, high quality images can be generated based on radio frequency signals, and therefore, fingerprint identification by radio frequency technology is a very reliable and powerful solution. In addition, the high quality image also allows the sensor volume to be reduced without sacrificing the reliability of authentication, thereby reducing the hardware cost and enabling the idea of radio frequency identification of fingerprints to be applied to the field of portable technology.

After the user authentication is passed, the obtained user fingerprint characteristic information can be used for encrypting the personal information of the user and then storing the personal information.
The fingerprint information analysis refers to analyzing fingerprint biological characteristic information, sending a trace amount of radio frequency signals through a radio frequency transceiver, detecting chemical reactions of underlying tissues of the skin after radio frequency irradiation, detecting changes of the surface layer of the skin of the finger, and acquiring related information. Due to factors such as black cells on the finger, red cells and moisture on the finger, the absorption and the generated chemical reaction of the radio frequency signal are different, and the returned signal is also different. The embodiment of the invention realizes fingerprint analysis by analyzing the reaction condition of different biological characteristics to the radio frequency signal and then correlating the characteristics with the relationship between the human body state.

The substance such as enzyme of human body is sensitive to a certain radio frequency signal, when the radio frequency signal stimulates the substance, the substance generates a certain frequency signal, and the embodiment of the invention utilizes a radio frequency transceiver to detect the change of the frequency so as to analyze and acquire the skin information.
