Referring to fig. 1, fig. 1 is a schematic structural diagram of a terminal device 100 according to an embodiment of the present invention, where the terminal device 100 includes: the mobile phone comprises a shell 10, a main board 20, a touch display screen 30, a battery 40 and an auxiliary board 50, wherein an infrared light source 21, an iris camera 22, a front camera 23, a processor 24, a memory 25, a SIM card slot 26 and the like are arranged on the main board 20, a vibrator 51, an integrated sound cavity 52, a VOOC flash charging interface 53 and a fingerprint module 54 are arranged on the auxiliary board, the infrared light source 21 and the iris camera 22 form an iris information acquisition device of the terminal equipment 100, the front camera 23 forms a facial information acquisition device of the terminal equipment 100, the fingerprint sensor module 24 forms a fingerprint information acquisition device of the terminal equipment 100, and the iris information acquisition device, the facial information acquisition device and the fingerprint information acquisition device are collectively called as a biological information acquisition device of the terminal equipment 100.
Wherein, the processor 24 is configured to light up a screen of the terminal device;

the processor 24 is further configured to determine an unlocking time corresponding to the last biological unlocking operation; and when the difference value between the unlocking time and the current system time is smaller than or equal to a first threshold value, taking the biological identification adopted by the latest biological unlocking operation as the biological identification of the current biological unlocking operation.
In an example, the processor 24 is further configured to determine N biometrics for a biometric unlocking operation within a preset time period when a difference between the unlocking time and the current system time is greater than the first threshold, where the preset time period includes the current system time, and N is a positive integer; and when M kinds of biological identification exist in the N kinds of biological identification, the number of times of using the M kinds of biological identification in the preset time period exceeds a second threshold value, and the safety level of the M kinds of biological identification is higher than a preset level, taking one kind of biological identification in the M kinds of biological identification as the biological identification of the current biological unlocking operation, wherein M is a positive integer.
In one example, processor 24 illuminates the screen of the terminal device before it

In one example, the set of templates includes at least one of: one or more fingerprint information templates, one or more iris information templates, and one or more face information templates.
Referring to fig. 2, fig. 2 is a schematic flowchart of an unlocking processing method provided in an embodiment of the present invention, and the method is applied to a terminal device, and includes the following steps:
step S201: the terminal device lights up a screen of the terminal device.
Step S202: when the screen of the terminal equipment is lightened, the terminal equipment starts biological unlocking operation, collects at least one piece of biological information input by a user, and carries out unlocking processing when the at least one piece of biological information is successfully matched with the template set.
Wherein the at least one type of biological information includes at least one of: fingerprint information, iris information, facial information, palm print information, voice print information, and the like.
Wherein the set of templates comprises at least one of: one or more fingerprint information templates, one or more iris information templates and one or more facial information templates, one or more voice print information templates, one or more palm print information templates.
The fingerprint information template may be a fingerprint data template, and the fingerprint data template is a set of correspondence between positions of feature points of a fingerprint surface of a registered user and feature values of the feature points (the feature values may be capacitances, inductances, voltages, currents, relative values, and the like).
The iris information template is an iris data template, and the iris data template is a collective image of correspondence between the positions of characteristic points of the iris of the registered user and characteristic values (the characteristic values may be capacitances, inductances, voltages, currents, relative values, and the like) of specific points.
The face information template is a face data template, and the fingerprint data template is a set of correspondence between positions of feature points of the face of the registered user and feature values of the feature points (the feature values may be capacitances, inductances, voltages, currents, relative values, and the like).
Step S201 and step S202 are executed in parallel, that is, there are two threads in the terminal device, one thread is used for executing step S201, and the other thread is used for executing step S202.
In an example, the method further comprises:
the terminal equipment matches each piece of biological information in the at least one piece of biological information with the template set; when each piece of biological information in the at least one piece of biological information is successfully matched with the template set, the terminal equipment determines that the at least one piece of biological information is matched with the template set; when at least one type of biological information does not match the template set, the terminal device determines that the at least one type of biological information does not match the template set successfully.
For example, assuming that the at least one type of biological information includes iris information and face information, the terminal device matches the iris information with one or more iris information templates of the template set, and matches the face information with one or more face information templates of the template set; when the iris information is matched with one iris information template in the template set and the face information is matched with one face information template in the template set, the terminal equipment determines that the at least one type of biological information is successfully matched with the template set; when the iris information is matched with one iris information template in the template set and/or the face information is matched with one face information template in the template set, the terminal equipment determines that the at least one biological information is unsuccessfully matched with the template set.
In the scheme, the biological identification operation is carried out by directly starting the biological unlocking operation while the screen is lighted, and the biological identification is started only by selecting the biological identification by a user without lighting the screen. Therefore, the time required by the biological unlocking operation can be shortened by adopting the scheme, and the speed of the biological unlocking operation is further improved.
In one example, the terminal device supports multiple biometrics, and before the terminal device collects at least one type of biometric information entered by a user, the method further includes:
the terminal equipment determines unlocking time corresponding to the latest biological unlocking operation;
and when the difference value between the unlocking time and the current system time is smaller than or equal to a first threshold value, the terminal equipment takes the biological identification adopted by the latest biological unlocking operation as the biological identification of the current biological unlocking operation.
Wherein the plurality of biometrics comprises at least one of: fingerprint recognition, iris recognition, facial recognition, voice print recognition, palm print recognition, and the like.
Wherein the last biological unlocking operation is a successful unlocking operation. The last biological unlocking operation refers to a biological unlocking operation which is closest to the current system time. For example, the terminal device records record information of a biological unlocking operation, the record information of the biological unlocking operation records 3 biological unlocking operations, the biological unlocking operation 1 corresponds to unlocking time 1, the biological unlocking operation 2 corresponds to unlocking time 2, the biological unlocking operation 2 corresponds to unlocking time 3, the biological unlocking operation 1 is successfully unlocked, the biological unlocking operation 2 is successfully unlocked, and the biological unlocking operation 3 is not successfully unlocked. If the unlocking time 1 is closest to the current system time, the last biological unlocking operation is the biological unlocking operation 1.
Wherein the first threshold is user-defined.
Alternatively, the first threshold is determined by the terminal device based on the recorded information of the biological unlocking operation. Specifically, the recorded information of the biological unlocking operation includes at least two biological unlocking operations, the unlocking times corresponding to the at least two biological unlocking operations are adjacent in the at least two biological unlocking operations, and the first threshold is determined by the terminal device according to the interpretation times corresponding to the at least two biological unlocking operations. For example, the record information of the biological unlocking operation records 3 biological unlocking operations, the biological unlocking operation 1 corresponds to an unlocking time 1, the biological unlocking operation 2 corresponds to an unlocking time 2, the biological unlocking operation 2 corresponds to an unlocking time 3, the time 1 is adjacent to the time 2, the time 2 is adjacent to the time 3, the time 3 is later than the time 2, and the time 2 is later than the time 1, so that the first threshold value { (time 3-time 2) + (time 2-time 1) }/2. Therefore, the first threshold is limited in the time range between two adjacent biological unlocking operations, and the timeliness of the biological identification selected by the previous biological unlocking operation can be effectively guaranteed.
For example, assuming that the first threshold is 10min, the unlocking time corresponding to the last biological unlocking operation is 16:10pm, the current system time is 16:15pm, and the biological recognition adopted by the last biological unlocking operation is iris recognition. It can be seen that (16:15pm-16:10pm) ═ 5min < the first threshold, then the biometric identification of this biometric unlocking operation is iris identification.
In an example, the method further comprises:
when the difference value between the unlocking time and the current system time is larger than the first threshold value, the terminal equipment determines N types of biological identification used for biological unlocking operation in a preset time period, wherein the preset time period comprises the current system time, and N is a positive integer;
and when the number of times that M kinds of biological identification are used in the preset time period exceeds a second threshold value and the safety level of the M kinds of biological identification is higher than a preset level, the terminal equipment takes one of the M kinds of biological identification as the biological identification of the current biological unlocking operation, and M is a positive integer.
Wherein the N biometrics comprise at least one of: fingerprint recognition, iris recognition, facial recognition, voice print recognition, palm print recognition, and the like.
Wherein the M biometrics comprise at least one of: fingerprint recognition, iris recognition, facial recognition, voice print recognition, palm print recognition, and the like.
The current system time is a middle node of the preset time period, or the current system time is a start node of the preset time period, or the current system time is a stop node of the preset time period, and so on, and the duration of the preset time period may be 1h, 2h, 2.5h, 3h, 3.5h, 1 day, or other values.
Wherein the second threshold is user-defined.
Alternatively, the second threshold is determined by the terminal device based on the recorded information of the biological unlocking operation. Specifically, the record information of the biological unlocking operation includes the number of times that the M kinds of biological identification are used within a preset time length, the second threshold is determined by the number of times that the M kinds of biological identification are used within the preset time length, and the preset time length is how long before the current system time. For example, assuming that the M biometrics includes fingerprint recognition, iris recognition, and facial recognition, the preset time period is the previous month from the current system. If the recorded information of the biological unlocking operation is recorded with: the number of times fingerprint recognition is used for a preset time period is 50, the number of times iris recognition is used for a preset time period is 70, the number of times face recognition is used for a preset time period is 30, and then the second threshold value is (50+70+30)/3 is 50.
It should be noted that, the number of times that the M biometrics are used in the preset time period refers to the number of times that the M biometrics are used for the biometric unlocking operation in the preset time period. The number of times that the M kinds of biometrics are used within the preset time period refers to the number of times that the M kinds of biometrics are used for the biometric unlocking operation within the preset time period.
The preset level is user-defined, or the preset level is user-defined by the terminal device, and so on.
In an example, when M > 1 is assumed, the specific implementation manner of the terminal device regarding one of the M biometrics identifications as the biometrics identification of the present biometric unlocking operation includes: the terminal equipment takes the biological identification with the highest security level in the M types of biological identification as the biological identification of the biological unlocking operation; or the terminal device takes the biological identification with the highest frequency used in the preset time period in the M types of biological identification as the biological identification of the current biological unlocking operation; and the terminal equipment takes the biological identification with the time used for the last time in the M types of biological identification closest to the current system time as the biological identification of the biological unlocking operation, and the like.
For example, assume that the first threshold is 10min, the unlocking time corresponding to the last biological unlocking operation is 16:10pm, the current system time is 16:30pm, the preset time period is 16: 00-17: 00, and the second threshold is 30. It can be seen that (16:30pm-16:10pm) — 20min > the first threshold. The terminal device determines N kinds of biological identification used for the biological unlocking operation within a preset time period of 16: 00-17: 00 according to record information of the biological unlocking operation, if N is 3, the 3 kinds of biological identification comprise fingerprint identification, iris identification and face identification, wherein the number of times of using the fingerprint identification within the preset time period of 16: 00-17: 00 is 40, the number of times of using the iris identification within the preset time period of 16: 00-17: 00 is 45, the number of times of using the face identification within the preset time period of 16: 00-17: 00 is 15, the safety level of the fingerprint identification is level 1, the safety level of the iris identification is level 3, the safety level of the face identification is level 2, wherein the level 3 is higher than the level 2, the level 2 is higher than the level 1, and the preset level is assumed to be level 2. It can be seen that the used times exceed 30 times in the preset time period of 16: 00-17: 00, and the biometric identification with the safety level higher than the level 2 is iris identification, so that the biometric identification of the current biometric unlocking operation is iris identification.
In an example, before the lighting the screen of the terminal device, the method further includes:
the terminal equipment determines matching thresholds corresponding to the multiple biological identifications respectively;
and the terminal equipment respectively determines the safety levels of the multiple biological identifications according to the matching threshold values respectively corresponding to the multiple biological identifications.
When the degree of matching between the biometric information entered by the user and the stored template reaches a certain value during biometric identification, it indicates that the biometric information matches with the stored template, and then the certain value is the matching threshold corresponding to biometric identification. For example, when the degree of matching between the fingerprint information entered by the user and the stored fingerprint template is greater than 80% during fingerprint identification, it indicates that the fingerprint information entered by the user matches with the stored fingerprint template, and then the matching threshold corresponding to fingerprint identification is 80%.
Further, different biometrics correspond to different matching thresholds. For example, the biometric identification includes fingerprint identification, iris identification and face identification, where the fingerprint identification corresponds to a matching threshold of 80%, the iris identification corresponds to a matching threshold of 90%, and the face identification corresponds to a matching threshold of 85%.
Or the matching thresholds corresponding to at least two types of biometrics in the plurality of biometrics are the same. For example, the biometric identification includes fingerprint identification, iris identification and face identification, where the fingerprint identification corresponds to a matching threshold of 80%, the iris identification corresponds to a matching threshold of 90%, and the face identification corresponds to a matching threshold of 80%.
The matching threshold corresponding to each of the multiple biometrics may be user-defined or terminal device-defined, and the present invention is not limited thereto.
In an example, the specific implementation manner of the terminal device determining the security levels of the multiple biometrics according to the matching thresholds corresponding to the multiple biometrics respectively includes: and the terminal equipment determines the security levels respectively corresponding to the multiple biological identifications according to the mapping relation between the matching threshold and the security levels and the matching threshold respectively corresponding to the multiple biological identifications.
For example, assuming various biometric fingerprints, iris recognition and facial recognition, the matching threshold corresponding to fingerprint recognition is 80%, the matching threshold corresponding to iris recognition is 90%, and the matching threshold corresponding to facial recognition is 80%. If the mapping relationship between the matching threshold and the security level is shown in table 1, the security level corresponding to fingerprint identification is level 1, the security level corresponding to iris identification is level 3, and the security level corresponding to face identification is level 2.
When any matching threshold value in the matching threshold value range I is larger than any matching threshold value in the matching threshold value range J, the security level I corresponding to the matching threshold value range I is larger than the security level J corresponding to the matching threshold value range J, and the matching threshold value range I and the matching threshold value range J are any matching threshold value range in the mapping relation between the matching threshold value and the security level.
