Abstract

The invention discloses a face verification system and a method based on visible light communications. The face verification method includes that a sending end internally arranged in a mobile terminal scans face information, converts the face information into digital information which representing the face information, and sends the digital information out through visible light signals; and a receiving end receives the visible light signals, extracts the digital information carried by the signals, and compares the digital information with preset verification information, and corresponding actions are implemented when the extracted digital information matches with the preset verification information. According to the face verification system and the method based on visible light communications, the face information is collected through the mobile terminal, compared with fingerprint collection by using fixed devices, counterfeit and deceive are not easy, information leakage can be prevented, and security is improved; further, the face information can be sent through the visible light signals, and user identification information is not easy to disclose due to the linear transmission of the light signals, so that security of face verification systems can be further improved.

Description

technical field [0001] The present invention relates to the technical field of visible light communication, in particular to a face verification system and method based on visible light communication. Background technique [0002] Wireless optical communication technology, also known as visible light communication, communicates through high-frequency flickering of LED light sources. Light represents 1, and no light represents 0. Its transmission rate is as high as gigabits per second. Wireless optical communication transmits data through visible light. Compared with microwave technology, it has quite abundant spectrum resources, which is unmatched by general microwave communication and wireless communication. At the same time, visible light communication can be applied to any communication protocol and any environment; In terms of reliability, there is no need to worry about the content of communication being stolen; the equipment of wireless optical communication is flexibl...
