Problems solved by technology

[0003] With the gradual maturity of biometric identification technology, smart devices also use biometric identification technology for identity authentication to improve the accuracy of identification and ensure information security. Commonly used biometric features on smart devices include fingerprints, face shapes, and irises. The method is mainly developed based on the Android and iOS platforms, and the fingerprint API provided by the Android system and the TouchID API provided by the iOS system do not provide accurate matching (one-to-one correspondence) for finger fingerprints, which will bring certain security risks, resulting in the so-called "Friendly Deception" for

Embodiment 1

[0050] like figure 1 shown, combined with image 3 , 4a , 4b and Figure 5 , now taking the user terminal device side as an example, the biometric identification method of the present invention includes:

[0051] S101. Enable the login function of the application through biometric identification;

[0052] S102. Provide a biometric verification interface so that the user can use a biometric stored in the terminal device to perform a biometric input operation;

[0053] S103. Verify the input biometrics. After the verification is passed, a pair of public and private keys will be generated for the account that logs in to the application, and the private key will be safely stored in the user terminal device; use the built-in device private key of the user terminal device to pair the account's public key and The account number and the index address of the biometric feature of the login account are signed;

[0054] In step S103, the device key is preset in the safe storage area ...

Embodiment 2

[0074] like figure 2 shown, combined with image 3 , 4a , 4b and Figure 5 , at the same time, the biometric identity identification method of the present invention is on the identity authentication server side, including

[0075] S201. Receive the registration request signed by the device private key built in the user terminal device, the registration request includes the account for logging in to the application, the public key generated by the user terminal device for the account, and the index address of the biometric feature of the login account; in the identity authentication server Store the device public key corresponding to the device private key of the user terminal device in advance, so as to verify the registration request signed by the device private key through the device public key, and save the application account contained in the registration request after the verification is passed. The generated public key and the biometrics of the login account.

Embodiment 3

[0084] In a second aspect, the present invention provides a user terminal device for biometric identity identification, the user terminal device has a biometric collection device (such as fingerprint collection, iris collection, voiceprint collection, etc.), and the collected biometrics can be stored and Matching to verify that the biometric feature has the authority to log in to the user terminal device is a well-known technology in the art, and the user terminal device of the present invention should be understood as having the above functions.

[0085] As an improvement, such as Image 6 As shown, the user terminal device of the present invention includes a storage medium 301 and a processor 302, and a computer program is stored in the storage medium, and when the program is run by the processor 302, the following steps are performed:

[0086] When logging in to the application program through biometric identification, a pair of public and private keys is generated for the ...

Abstract

The invention discloses a method for recognizing an identity through a biological feature. At a user terminal device side, a pair of public and private keys are provided for an account which logs in an application in a biological feature recognition mode; the account, a public key of the account and a biological feature index address of a login account are signed through a built-in device private key; a registration request is generated based on the account, the public key of the account and the biological feature index address of the login account; and the registration request is checked through a device public key pre-stored in an identity authentication server, after the check is successful, the account, the public key of the account and the biological feature index address of the login account are stored, thereby checking an authentication request of the terminal device. According to the method, double public and private key authentication and once biological feature comparison check authentication are carried out on the biological feature of the login account, the precise matching of the biological feature of the login account is ensured, the biological feature with the right to logging the terminal device is further authenticated and then the service (such as transaction service related to money) of the application can be used, the friendly cheat is avoided, and the privacy and property safety is improved.

Description

technical field [0001] The invention relates to the technical field of identity verification applied to smart devices, in particular to a method and system for identifying identity with biometric features. Background technique [0002] With the rapid development and popularization of electronic technology and Internet technology, various smart devices such as smart phones, tablets and various wearable devices are advancing by leaps and bounds. While realizing basic communication functions, another important function is to bind bank cards or Credit cards and other online payments, that is to say, in a smart device may not only contain the privacy of communication content, but also bind personal property and store important file information; therefore, while people enjoy a smarter and more convenient life, they are also facing There are increasingly serious risks to privacy and property security. [0003] With the gradual maturity of biometric identification technology, smart...
