The Mobile terminal according to the embodiment of the present invention may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, and various forms of User Equipment (UE), Mobile Stations (MS), terminal devices (terminal device), and the like, which have wireless communication functions. For convenience of description, the above-mentioned devices are collectively referred to as a mobile terminal.
The following describes embodiments of the present invention in detail.
In order to better understand the embodiment of the present invention, the working principles of fingerprint recognition, iris recognition and face recognition in the embodiment of the present invention are first described. Referring to fig. 1a, fig. 1a is a schematic view illustrating an operation principle of multi-biometric identification according to an embodiment of the present invention. The multi-biometric identification in fig. 1a is applied to a mobile terminal, which is exemplified by a mobile phone. As shown in fig. 1a, the iris camera 110, the fingerprint recognition module 120, the front camera 130 and the display screen 140 are all disposed on the front side of the mobile phone 10, wherein the fingerprint recognition module 120 is used for collecting fingerprint images, the iris camera 110 is used for collecting iris images (the iris images may be black and white iris images, and when the iris camera 110 works, light supplement may be performed through a front infrared flash), and the front camera 130 is used for collecting face images.
Optionally, an Application Processor (AP) 150 and a memory 160 may also be included in fig. 1 a. The AP150 is used to verify the collected fingerprint image, iris image, and face image. The AP150 and the memory 160 are not directly visible from the appearance of the handset 10, and are shown in dashed lines in fig. 1 a.
In the embodiment of the present invention, the AP150 may match the fingerprint image collected by the fingerprint identification module 120 with the preset fingerprint template stored in the memory 160, and if the matching is successful, it is determined that the fingerprint identification is verified. The AP150 may match the iris image collected by the iris camera 110 with a preset iris image stored in the memory 160, and if the matching is successful, it is determined that the iris recognition verification is passed. The AP150 may match the face image collected by the front camera 130 with a preset face image stored in the memory 160, and if the matching is successful, it is determined that the face recognition verification is passed. The biometric identification of the embodiment of the invention can be used for scenes of screen unlocking, mobile phone payment unlocking and the like which need to be unlocked and subjected to security authentication.
Referring to fig. 1b, fig. 1b is a schematic structural diagram of a mobile terminal according to an embodiment of the present invention, as shown in fig. 1b, the mobile terminal 100 includes an Application Processor (AP) 101 and a first biometric module 102, wherein the AP101 is connected to the first biometric module 102 through a bus 103.
And the AP101 is configured to acquire a security level of WiFi to which the mobile terminal 100 is connected, and acquire a first target biometric identification manner corresponding to the security level of WiFi according to a correspondence between the security level and the biometric identification manner. Among them, WiFi (English: Wireless-Fidelity, Chinese: Wireless Fidelity) may also be called a Wireless network.
In the embodiment of the present invention, the security level of the WiFi to which the mobile terminal 100 is connected may be determined according to a preset rule. For example, the security level of WiFi may be set to "lower" if it is first connected and set to "higher" if it is not first connected and the connection frequency is higher, depending on whether it is first connected. For another example, the security level of WiFi may be set to "higher" if the WiFi is corporate WiFi or home WiFi and set to "lower" if the WiFi is neither corporate WiFi nor home WiFi, depending on whether the WiFi is corporate WiFi or home WiFi. Specifically, if the same WiFi is connected when detecting that N consecutive days (where N is an integer greater than or equal to 2) are 1 am, the WiFi is set as a home WiFi; if the same WiFi is connected at 10 am for M consecutive days (where M is an integer greater than or equal to 2 and less than or equal to 5) on the working day, the WiFi is set as the working WiFi.
The security level of the WiFi to which the mobile terminal 100 is connected may also be set by the user. The user clicks the WiFi setting interface, and then the WiFi hotspot name list of the historical connection of the mobile terminal 100 can be displayed, and the user sets in sequence.
The correspondence between the security level and the biometric method may be stored in advance in a memory (e.g., a nonvolatile memory) of the mobile terminal 100, and the security level may be set to "high", "low", and "medium". Referring to table 1, table 1 is a table of correspondence between security levels and biometric methods according to an embodiment of the present invention.
TABLE 1
| Level of security | Biometric identification method |
| Is higher than | Face recognition |
| Medium and high grade | Fingerprint identification |
| Is lower than | Iris recognition |
As can be seen from table 1, the higher the security level, the lower the security of the biometric method employed, and the faster the unlocking speed. The user experience can be improved.
The security level of the WiFi to which the mobile terminal 100 is connected may also be displayed numerically. For example, the security level is less than 3, and the corresponding biometric identification mode is iris identification; the security level is 3-7, and the corresponding biological identification mode is fingerprint identification; the safety level is higher than 7, and the corresponding biological identification mode is face identification.
Optionally, the security level of WiFi is determined based on the connection frequency of WiFi and the accumulated connection duration of WiFi.
For example, if the connection frequency of WiFi with a security level of L is f, and the cumulative connection duration of WiFi is t, L ═ a × f + b × t, where a and b are corresponding weighting coefficients, e.g., a ═ b ═ 0.5.
In the embodiment of the invention, the safety level of the WiFi is determined based on the historical connection frequency of the WiFi and the historical accumulated connection duration of the WiFi. The mobile terminal 100 may count the connection frequency and the accumulated connection duration for each WiFi connected for a period of time (e.g., for the past month). Generally, the higher the connection frequency of WiFi, the higher the security level is relatively, and the longer the cumulative connection time of WiFi, the higher the security level is. The embodiment of the invention can calculate the safety level of the WiFi according to the connection frequency of the WiFi and the accumulated connection duration of the WiFi, and the calculation mode is simple.
The first biometric module 102 is configured to collect first target biometric information according to a first target biometric identification manner.
In this embodiment of the present invention, if the first target biometric identification method is face identification, the first biometric identification module 102 is a face identification module, and the first target biometric information is a face image. The face recognition module can include leading camera and leading flash light, and leading camera is used for shooing the face image, and the leading flash light carries out the visible light filling when being used for leading camera shooting face image.
If the first target biometric identification mode is fingerprint identification, the first biometric identification module 102 is a fingerprint identification module, and the first target biometric information is a fingerprint image. Fingerprint identification module is used for gathering the fingerprint image.
If the first target biometric identification mode is iris identification, the first biometric identification module 102 is an iris identification module, and the first target biometric information is an iris image. The iris identification module can comprise an iris camera and an infrared flash lamp, the iris camera is used for shooting iris images, and the infrared flash lamp is used for infrared light supplement when the iris camera shoots the iris images.
The AP101 is further configured to verify whether the first target biological information is valid biological information, and perform an unlocking operation when the first target biological information is valid biological information.
In the embodiment of the invention, if the first target biological information is the face image. The method for the AP101 to verify whether the face image is a legal face image is specifically as follows:
the AP101 verifies whether the face image is matched with a face image template stored in advance;
when the face image is matched with the face image template stored in advance, the AP101 determines that the face image passes the face recognition verification, and may perform operations such as unlocking.
When the face image is not matched with the face image template stored in advance, the AP101 determines that the face image cannot pass the face recognition verification, and may output prompt information for prompting that the face recognition fails.
In an embodiment of the present invention, the face image template may include face features, such as eye features (e.g., eyeball size and shape, eye distance, etc.), nose features (nostril distance, nose tip length, etc.), mouth features (lip thickness, lip length, etc.), combination features (distance between nostril to left eye and right eye, distance between left eye to lip, etc.).
Optionally, before verifying whether the face image matches with the face image template stored in advance, the AP101 may convert the face image into a standardized image, where the standardization process includes pixel standardization, image size standardization, and the like.
If the first target biological information is a fingerprint image, the way for the AP101 to verify whether the fingerprint image is a valid fingerprint image is specifically:
AP101 draws the fingerprint characteristic information in the fingerprint image of fingerprint identification module collection to the fingerprint characteristic information that will draw matches with the fingerprint template of predetermineeing of storage in the memory, if match, then confirms to pass through fingerprint identification. The fingerprint template is generated by extracting fingerprint characteristic information from one or more fingerprint images acquired in advance and according to the extracted fingerprint characteristic information.
If the first target biological information is the iris image, the mode of the AP101 verifying whether the iris image is a legal iris image is specifically as follows:
the AP101 verifies whether the iris image is a legal iris image, and may specifically be:
the AP101 extracts iris characteristic points in the iris image and codes the iris characteristic points to obtain iris characteristic codes;
the AP101 compares whether the iris feature code is matched with the iris feature code stored in advance;
if the iris image is matched with the legal iris image, the AP101 confirms that the iris image is the legal iris image;
if not, the AP101 confirms that the iris image is an illegal iris image.
When the iris image is a legal iris image, the AP101 confirms that the iris identification verification is passed; an unlocking operation can be performed.
Alternatively, when the iris image is an illegal iris image, the AP101 confirms that the iris identification cannot be verified.
Optionally, the AP101 is further configured to set the unlocking manner of the mobile terminal as the first target biometric identification manner after obtaining the first target biometric identification manner corresponding to the security level of the WiFi according to the correspondence between the security level and the biometric identification manner.
By implementing the mobile terminal 100 shown in fig. 1b, the biometric identification mode may be determined according to the security level of the WiFi connected to the mobile terminal 100, and the biometric identification mode corresponding to the security level of the WiFi is used to unlock the mobile terminal, so that the security of unlocking the mobile terminal 100 may be improved.

In this embodiment of the present invention, the geographic location information of the mobile terminal 100 may include longitude and latitude of the mobile terminal 100, for example, in a certain longitude range and a certain latitude range, corresponding to a biometric identification mode. For example, a region centered at home or a region centered at company corresponds to a face recognition mode or a fingerprint recognition mode; and the other areas correspond to the iris recognition mode.
And if the first target biological identification mode is the same as the second target biological identification mode, the biological identification mode determined according to the WiFi connected with the mobile terminal is the same as the biological identification mode determined according to the geographic position information of the mobile terminal, and the mobile terminal performs unlocking verification by adopting the same biological identification mode.
Optionally, the AP101 is further configured to verify whether the first target biometric information is valid biometric information when the first target biometric identification manner is different from the second target biometric identification manner and the security of the first target biometric identification manner is greater than the security of the second target biometric identification manner.
