In order to solve the problem that the user worry about leakage of personal biological characteristic information, when transacting financial business, a financial institution initiates an authentication request to a mobile device private to the user and performs biological characteristic authentication in the mobile device, and the authentication result is fed back to the financial institution through the mobile device, and the financial institution approves the authentication result of the mobile device and transacts the financial business. However, when the mobile device collects the biometric information and verifies the biometric information, if the biometric information is invaded by the computer malicious program, the biometric verification result obtained by the financial institution may not be a real verification result, for example, after the financial institution initiates the authentication request, the mobile device collects the biometric information of the user and performs the biometric verification, and the obtained verification result is not passed, but at this time, the computer malicious program invades the mobile device and replaces the verification result with the verification pass, and the financial institution processes the financial service after receiving the verification result tampered by the malicious program, which definitely causes a great potential safety hazard to the processing of the financial service.

For example, the request handling information is processed through an encryption server, the total number N of the biological characteristics to be collected and the second serial numbers of N quantum random numbers corresponding to the target financial service are obtained after the request handling information is processed, for example, the biological characteristics can be a portrait, a fingerprint, an iris, a palm vein and the like, an identity verification message is obtained according to the total number N of the biological characteristics to be collected and the second serial numbers of N quantum random numbers corresponding to the target financial service, then the first serial numbers of at least one quantum random number and the identity verification message are encrypted according to a preset transmission key, and encrypted first data information is obtained.
Step S103, verifying the biological characteristics of the target object based on the first data information by the target device to obtain a first verification result, and sending second data information to the encryption server by the target device when the first verification result represents that the verification is passed, wherein the second data information is encrypted data information, and at least comprises: and the verification result message at least comprises a first verification result.
For example, the target device verifies the biological characteristics of the target object according to the first data information to obtain a first verification result, if the first verification result indicates that the biological characteristics of the target object pass verification, the verification result message including the first verification result and the third serial number of at least one quantum random number are encrypted according to a preset transmission key to obtain second data information, and the second data information is sent to the encryption server through the target device.
Step S104, verifying the second data information through the encryption server to obtain a second verification result, and transacting the target financial business through the target equipment under the condition that the second verification result represents verification pass.
For example, the authenticity of the second data information is verified by the encryption server, a second verification result is obtained, if the second verification result indicates that the verification is passed, the biometric verification of the target object is indicated to be passed, and the verification result of the biometric is also reliable, so that the target financial service can be transacted through the target device.
In summary, in the application, the target device receives the processing request information of the target financial service initiated by the target object, sends the processing request information to the encryption server, the encryption server processes the processing request information to obtain the first data information, then sends the first data information to the target device, the target device verifies the biological characteristics of the target object according to the first data information to obtain a first verification result, and sends the second data information to the encryption server when the first verification result indicates that the verification is passed, the encryption server verifies the second data information and sends the second verification result to the target device, and the target device processes the target financial service when the second verification result indicates that the verification is passed.
