Problems solved by technology

But the deficiencies that still exist in this device and method are: First, the method only involves three modes of infrared spectrum biometrics technology, hand type biometrics technology, and fingerprint biometrics technology, and the above three modes all belong to Hand features, biometric features other than the above three features cannot be collected and applied

But the weak point that this method still exists is: one, this method only comprises the combined authentication of voice and face feature value, and voice and face feature all have higher falsification, cause the anti-counterfeiting of this system to be relatively low. Difference

However, the system still has shortcomings: the system needs to be built in a wide area network, and even the comparison of biometric values ​​needs to send a comparison request to the database server through the local area network, which consumes a lot of network resources.

However, the system and method still have disadvantages as follows: First, the intelligent biometric collection and processing terminal described in the system is a biometric collection and processing terminal with a built-in or external biometric collection device. After obtaining the biometric information of the user, the corresponding intelligent biometric collection and processing terminal can only perform preprocessing such as calculation, extraction of characteristic data, comparison and storage of the information, and information comparison needs to transmit the preprocessing results to the identity authentication service module through the network For comparison, when the network is interrupted or the identity authentication service module fails, identity authentication cannot be performed

However, the shortcomings of this module are: the module has a single function and can only integrate one biometric mode. Once integrated, other modes cannot be converted, which leads to the defect of limited application.

But the deficiencies that still exist in this device are: First, because this device is integrated in the mobile terminal, in order to achieve the characteristics of portability and flexibility, the integration of the data acquisition module will be greatly restricted, and the application is limited to IC card, fingerprint, face and iris

Second, the device integrates four limited types of biometric acquisition modules in the mobile terminal in advance, so the model of the acquisition module cannot be flexibly selected, and the replacement of equipment is restricted

Third, the output module of the device only completes the output of the interface and voice during human-computer interaction, and does not save the recognition results. When other application systems need to obtain their recognition results through network connections, the network interruption and application system failure The original record retention and resume function cannot be guaranteed, resulting in data loss

Fourth, in this method, there is a setting about multiple biometric items and order in the setting of the configuration file, and the combined authentication involving multiple biometric items in the authentication method must be authenticated in the order set in advance. It is easy to forget the order, even if the system prompts to identify the order, it cannot take care of the user's individual usage habits

[0010] With the rapid development of biometric technology, different types, different brands and models of biometric acquisition devices have emerged, and there are many types. Because there is no standard communication protocol at present, each device must be manually installed before use. Self-contained driver and application system
