The embodiment of the invention provides an unlocking control method and a related product, which are used for solving the technical problem of insufficient operation convenience caused by the fact that one of a plurality of pieces of biological verification information is required to be verified again after verification fails.
The mobile terminal described in the embodiment of the present invention is provided with a biometric identification device, and the biometric identification device specifically includes at least a fingerprint identification module, an iris identification module, a face identification module, and may further include a voice identification module, a vein identification module, a sclera identification module, and other biometric identification modules.

Embodiments of the present invention will be described below with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a mobile terminal 100 according to an embodiment of the present invention, where the mobile terminal 100 includes: the casing, the touch-control display screen, the mainboard, battery and subplate, be provided with infrared light source 21 on the mainboard, infrared camera 22, leading camera 23, treater 110, memory 120 and customer identification Module (Subscriber Identity Module, SIM) draw-in groove etc. be provided with the oscillator on the subplate, integrative sound chamber, VOOC dodges and fills interface and fingerprint sensor Module 24, the iris identification Module of this mobile terminal 100 is constituteed to above-mentioned infrared light source 21 and infrared camera 22, the facial identification Module of this mobile terminal 100 is constituteed to above-mentioned leading camera 23, the fingerprint identification Module of this mobile terminal 100 is constituteed to above-mentioned fingerprint sensor Module 24.
When the biometric device is an iris recognition module, the infrared light source 21 is configured to emit infrared light to irradiate the iris of the user to form reflected light, the infrared camera 22 is configured to collect the reflected light to form an iris image, and after the processor 110 acquires the iris image, the processor 110 performs processing procedures such as iris image quality evaluation, iris region positioning (including coarse positioning and fine positioning), iris preprocessing, iris feature point extraction, and iris template generation on the iris image, and the generated iris template is biometric information to be verified.
Based on the mobile terminal 100 described in fig. 1, the following operations may be performed:
in an embodiment of the present invention, the biometric device is configured to acquire M pieces of biometric authentication information.
Wherein M is an integer greater than 1. And each verification operation is provided with a verification sequence and a biometric identification module called in each verification step, and after the verification operation is triggered, the mobile terminal starts a corresponding biometric identification device to acquire biometric verification information to obtain a plurality of biometric verification information.
For example, the biometric device called for screen unlocking verification is a fingerprint identification module and a face identification module, and when a user touches the touch display screen integrated with the fingerprint identification module after waking up the screen, the touch display screen notifies the fingerprint identification module to collect fingerprint verification information and notifies the face identification module to collect face verification information after detecting the touch operation.
In the embodiment of the present invention, the memory 120 is used for storing preset conditions. The processor 110 is configured to verify the M pieces of biometric authentication information; when at least one piece of biological verification information in the M pieces of biological verification information fails to be verified, obtaining verification data corresponding to the M pieces of biological verification information; and when the verification data meets the preset condition, confirming that the verification is successful.
The preset condition is not limited in the embodiment of the present invention, and the preset condition may include at least one of the following: the verification sequence, the matching threshold of each piece of biometric verification information and the preset biometric verification information, the acquisition time of each piece of biometric verification information, the ratio of the number of successfully verified biometric verification information to M, and the like.
It can be seen that, in the embodiment of the present invention, when M pieces of biometric authentication information are authenticated, at least one piece of biometric authentication information fails to be authenticated, the authentication data corresponding to the M pieces of biometric authentication information is obtained, and when the authentication data satisfies the preset condition, it is determined that the current authentication operation is successfully authenticated, and then the authentication does not need to be performed again, thereby improving the security of the authentication data and the convenience of the operation.
The processor 110 obtains a matching value between each piece of biometric authentication information in the M pieces of biometric authentication information and the preset biometric authentication information, and obtains M matching values. Judging whether the preset condition is met according to the average value or the weighted average value, the maximum matching value, the minimum matching value or a plurality of the M matching values, wherein the preset condition is not limited in the embodiment of the invention.
Optionally, the verification data includes M matching values; the preset condition is that at least two matching values in the M matching values meet the corresponding matching conditions. That is, the preset condition is satisfied as long as two of the matching values satisfy the matching condition.
For example, assume that the matching threshold for the fingerprint recognition module is 85%, the matching threshold for the voice recognition module is 80%, and the matching threshold for the face recognition module is 88%. When the matching value of the face image and the preset face image is 80%, the matching value of the fingerprint image and the preset fingerprint image is 88%, and the matching value of the sound information and the preset sound information is 90%, two matching values satisfy the corresponding matching conditions, that is, it is confirmed that the preset conditions are satisfied, that is, the verification is successful.
In one possible example, the verification data comprises a verification order and M matching values; the memory 120 is further configured to store a preset verification sequence and a first threshold; the processor 110 is further configured to obtain an evaluation value of the verification data according to the M matching values when the verification order is consistent with the preset verification order; and confirming that the verification data satisfies the preset condition when the evaluation value is greater than or equal to the first threshold.
The evaluation value may be a weighted average value of a plurality of performance parameters, the verification performance parameters may include verification time, a matching value, power consumption, and the like, and the evaluation value calculated according to a plurality of dimensions of the verification data may improve description accuracy of the evaluation value, thereby improving security of the verification data.
Optionally, the memory 120 is further configured to store a weight corresponding to each matching value; in terms of the processor 110 obtaining the evaluation value of the verification data according to the M matching values, the processor 110 is specifically configured to: and acquiring the evaluation value according to each matching value in the M matching values and the weight value corresponding to the matching value.
For example, assuming that the first threshold is 0.8, the preset verification sequence is the fingerprint identification module, the voice identification module and the face identification module in sequence, wherein the matching threshold corresponding to the fingerprint identification module is 80% and the weight is 0.6; the matching threshold corresponding to the voice recognition module is 80%, and the weight is 0.3; the matching threshold corresponding to the face recognition module is 80% and the weight is 0.1. If the matching value of the fingerprint image collected by the fingerprint identification module and the preset fingerprint image is 88%, the matching value of the voice fragment collected by the voice identification module and the preset voice fragment is 78%, and the matching value of the face image collected by the face identification module and the preset face image is 82%, the voice identification module fails to verify, and if the verification sequence is consistent with the preset verification sequence, the evaluation value of 88% + 0.6+ 78% + 0.3+ 82% + 0.1 is calculated to be 0.844 and is greater than a first threshold, the verification data is confirmed to meet the preset condition, namely, the verification is successful. By calculating the evaluation values of the plurality of matching values, the description accuracy of the evaluation values can be improved, thereby improving the security of the verification data.
In one possible example, the biometric identification device further comprises an alternative biometric acquisition module; the memory 120 is further configured to store preset target biometric authentication information and a second threshold; the biometric identification device is further configured to control the candidate biometric identification module to acquire target biometric verification information after the processor 110 obtains the evaluation value of the verification data according to the M matching values; the processor 110 is further configured to obtain a target matching value between the target biometric authentication information and the preset target biometric authentication information when the evaluation value is smaller than the first threshold; and when the target matching value is greater than or equal to the second threshold value, confirming that the verification data meets the preset condition.
The alternative biometric module in the embodiment of the present invention is not limited, and may be a preset biometric module, one of historical multi-biometric modules, a biometric module obtained according to an absolute value of a difference between the evaluation value and the first threshold, or the like. It should be noted that the alternative biometric module includes at least one biometric module, thereby improving the security of the authentication.
For example, assuming that the evaluation value is 0.706, as shown in table 1, the relationship between the evaluation value range and the candidate biometric module, the candidate biometric module may be obtained as a voice recognition module and a face recognition module.
TABLE 1
| Evaluation value range | Alternate biometric module |
| [0,0.2] | Fingerprint identification module, voice identification module and iris identification module |
| [0.2,0.4] | Fingerprint identification module, voice identification module and face identification module |
| [0.4,0.6] | Voice recognition module and iris recognition module |
| [0.6,0.8] | Voice recognition module and face recognition module |
| [0.8,1.0] | Fingerprint identification module |
That is, when the evaluation value is less than the first threshold, the candidate biometric identification module may be enabled to collect the target biometric authentication information, and when a target matching value between the target biometric authentication information and the preset target biometric authentication information is greater than or equal to the second threshold, it is confirmed that the preset condition is satisfied, and authentication is performed by the candidate biometric identification module without a user having to tangle an authentication sequence and an authentication step in which authentication fails, thereby improving security of authentication data and convenience of operation.
For example, assuming that the first threshold is 0.85, the preset verification sequence is the fingerprint identification module, the voice identification module and the face identification module in sequence, wherein the matching threshold corresponding to the fingerprint identification module is 80% and the weight is 0.6; the matching threshold corresponding to the voice recognition module is 80%, and the weight is 0.3; the matching threshold corresponding to the face recognition module is 80% and the weight is 0.1. If the matching value of the fingerprint image collected by the fingerprint identification module and the preset fingerprint image is 88%, the matching value of the voice fragment collected by the voice identification module and the preset voice fragment is 78%, and the matching value of the face image collected by the face identification module and the preset face image is 82%, the voice identification module fails in verification, and if the verification sequence is consistent with the preset verification sequence, the alternative biometric identification module is obtained if the calculated evaluation value is 88% 0.6+ 78% 0.3+ 82% 0.1-0.844 and is smaller than a first threshold value. If the alternative biometric identification module is the iris identification module and the second threshold value is 90%, the iris identification module is used for collecting the iris image, and when the matching value of the iris image and the preset iris template is greater than 90%, the verification data meets the preset condition, namely the verification is successful, and the verification operation can be successfully verified without re-verification, so that the convenience of operation is improved. By calculating the evaluation values of the plurality of matching values, the description accuracy of the evaluation values can be improved, thereby improving the security of the verification data.
Optionally, a target matching value between the target biometric authentication information and preset target biometric authentication information is obtained; when the target matching value is smaller than a second threshold value, determining a second evaluation value according to the target matching value and a weight value corresponding to the target matching value; confirming that the verification is successful when the second evaluation value is greater than the evaluation value. That is, when the verification of the candidate biometric module fails, as long as the second evaluation value of the matching value of the candidate biometric module is greater than the evaluation value, the verification is confirmed to be successful, thereby improving the recognition rate of the verification.

It can be seen that, in the embodiment of the present invention, when M pieces of biometric authentication information are authenticated, at least one piece of biometric authentication information fails to be authenticated, the authentication data corresponding to the M pieces of biometric authentication information is obtained, and when the authentication data satisfies the preset condition, it is determined that the current authentication operation is successfully authenticated, and then the authentication does not need to be performed again, thereby improving the security of the authentication data and the convenience of the operation.
In one possible example, the verification data contains M matching values; the preset condition is that at least two matching values in the M matching values meet the corresponding matching conditions.
In one possible example, the verification data contains a verification order and M matching values; the memory stores a preset verification sequence and a first threshold; when the verification sequence is consistent with the preset verification sequence, the processor acquires evaluation values of the verification data according to the M matching values; and confirming that the verification data satisfies a preset condition when the evaluation value is greater than or equal to the first threshold.
