Referring to fig. 1B, fig. 1B is a schematic flow chart of an unlocking control method according to an embodiment of the present invention, and as shown in the figure, the unlocking control method includes:
s101, a mobile terminal acquires a plurality of pieces of biological information of a plurality of users, wherein the plurality of pieces of biological information comprise first biological information of a first user and second biological information of a second user;
the mobile terminal may acquire a plurality of pieces of biological information of a plurality of users through the front camera module, or may acquire a plurality of pieces of biological information of a plurality of users through the rear camera module, which is not limited herein.
For example, as shown in fig. 1C, the mobile terminal may obtain the first biological information of the first user through the front-facing camera and obtain the second biological information of the second user through the rear-facing camera at the same time, or as shown in fig. 1D, obtain the first biological information of the first user and the second biological information of the second user through the front-facing camera at the same time.
In one possible example, the mobile terminal includes a camera device, such as a front camera and a rear camera, and the acquiring the multiple pieces of biological information of the multiple users includes: and acquiring first biological information of the first user through the front camera, and acquiring second biological information of the second user through the rear camera.
Therefore, in the example, the camera device does not need additional interaction operation of the user to acquire the biological information, so that the identification process is very convenient, the interaction process is few, the processing efficiency is high, the first biological information of the first user and the second biological information of the second user can be acquired simultaneously through the front camera and the rear camera, the stable acquisition of the biological information of different users is facilitated, and the stability and the efficiency of the unlocking operation of the mobile terminal are improved.

In a possible example, when the unlocking operation is a payment unlocking operation of a first payment amount, the detecting that the first operation and the second operation are both successfully matched includes: when the matching degree of the first operation and the second operation is detected to be larger than a third preset threshold, the first operation and the second operation are successfully matched, and the first payment amount is larger than a preset amount;
when the unlocking operation is a payment unlocking operation of a second payment amount, the detecting that the first operation and the second operation are successfully matched comprises the following steps: when the matching degree of the first operation and the second operation is detected to be larger than a fourth preset threshold, the first operation and the second operation are successfully matched, the second payment amount is smaller than the preset amount, and the third preset threshold is larger than the fourth preset threshold.
Therefore, in this example, when the mobile terminal solves the to-be-unlocked operation under the payment condition, the preset threshold of the matching degree is determined according to the payment amount grades, which is beneficial to improving the intelligence of the unlocking operation of the mobile terminal, the safety of large-amount payment and the rapidity of small-amount payment.
