The technical solution provided by the embodiment of the present application adopts mixed biometric information for comprehensive identification. The technical solution can effectively improve the accuracy of identification without increasing the complexity of the operation, thereby enhancing the security of the security system and improving User experience.

FIG. 1 shows a flowchart of an identification method according to an embodiment of the present application. The method may be applied to a server side or a terminal side. As shown in FIG. 1, the identification method includes the following steps S101-S103 :

In step S101, first biometric information of an object to be identified is acquired, and first identity recognition is performed on the object to be identified according to the first biometric information;

In step S102, in response to the success of the first identity recognition, acquiring second biometric information of the object to be identified;

In step S103, a second identity is performed on the object to be identified according to the second biometric information.

As mentioned above, with the development of data technology and social progress, the public has higher and higher requirements for security systems. At present, the identity recognition in security systems usually uses 2D recognition technologies such as face recognition, fingerprint recognition, or pupil recognition, but due to the high misrecognition rate of the 2D recognition technology, it is far from meeting the increasing requirements of the public for security systems. .

In view of the above problems, in this embodiment, an identification method is proposed. This method uses mixed biometric information for comprehensive identification, that is, adopts a dual identification mechanism. This technical solution does not increase the complexity of the operation. It can effectively improve the accuracy of identity recognition, thereby enhancing the security of the security system and improving the user experience.

In an optional implementation manner of this embodiment, the first biometric information includes one or more of the following feature information: a face image, a pupil image, and a fingerprint image, wherein the face image, the pupil, Both the image and the fingerprint image can be a three-dimensional image or a two-dimensional image. The three-dimensional image has a high accuracy rate but a large amount of calculation, and a two-dimensional image has a small amount of calculation but a low accuracy rate. Those skilled in the art can provide a first biological The feature information is selected, which is not specifically limited in this application.

In an optional implementation manner of this embodiment, the second biometric information is voiceprint data, and the voiceprint data refers to a sound wave spectrum carrying speech information displayed by an electroacoustic instrument. Because the vocal organs used by people in speech: tongue, teeth, throat, lungs, and nasal cavity are all different in size and shape, that is, the voiceprint patterns of any two people are also different, and the acoustic characteristics of each person's speech It has both relative stability and variability. Therefore, voiceprint data can be used to achieve identity recognition.

In an optional implementation manner of this embodiment, the acquisition of the first biometric information may be performed by using an image acquisition device such as a camera or a camera.

In this embodiment, if the first identity is successful and the second identity is unsuccessful, it is temporarily considered that there may be an impact event when obtaining biometric information, so the first biometric information may be repeatedly obtained for the first identity recognition. After the first identity is successfully obtained, the second biometric information is repeatedly obtained for the second identity recognition, or in order to save the calculation amount and the calculation time, the second biometric information may also be obtained directly for the second identity recognition.
