Identity verification system based on face recognition

The invention discloses a network device based on a customer identity verification system, which aims to solve the problem that the cases resulting from name borrow and false name happen occasionally due to the shortcomings existing in the process of manually verifying the customer identity in the current financial industry. A customer terminal consists of a group of self-service information acquisition and real-time comparison terminals which perform real-time comparison on the information acquired by a camera and a second-generation identity card reader and directly transmit the acquired information and the comparison result to a background server or forward through a middleground server; and a third-party server reads the required information and comparison result directly from the background server database through a communication interface or through the middleground server. Through the invention, the identification accuracy of the customer identity is high, and the cases resulting from name borrow and false name in the banking business are greatly reduced. In combination with the characteristics of the bank, the information can be acquired in a self-service manner and automatically identified and compared to avoid human risk in the banking business, thereby laying a firm foundation for the sustainable development of the bank.
