and step S10, detecting the signal intensity of wireless connection with the intelligent bracelet. The strength of the signal wirelessly connected with the intelligent bracelet by the mobile terminal is related to the distance between the mobile terminal and the intelligent bracelet, and the distance is long, the signal is weak, the distance is short and the signal is strong; when the distance is long (namely, when the signal strength is weak), the privacy is easy to leak, and the privacy protection of the preset application program needs to be enhanced, namely, encryption is carried out. Preferably, before step S10, the mobile terminal is connected to the smart band through bluetooth, and enters a preset encryption mode corresponding to the connection relationship in the background of the mobile terminal, where the corresponding encryption mode is that the mobile terminal enters the preset (application) encryption mode when the mobile terminal and the smart band start to be connected.
And step S20, when the signal intensity is lower than a preset threshold value, acquiring the facial features of the current user of the mobile terminal. Specifically, when the signal intensity is lower than a preset threshold, a front-facing camera of the mobile terminal is started to detect the facial features of the current user. And if the signal intensity is changed from strong to weak until the wireless connection between the intelligent bracelet and the mobile terminal is disconnected, controlling a preset application program of the mobile terminal to enter a second preset encryption state.
And step S30, controlling the preset application program of the mobile terminal to enter a preset encryption state according to the acquired facial features.
As a preferred embodiment of the present invention, the implementation manner of step S30 is:
judging the similarity between the acquired facial features and the facial features preset in the mobile terminal;

when the time length of the mobile terminal entering the second preset encryption state reaches T2, controlling a preset application program of the mobile terminal to enter a first preset encryption state;
wherein T1 represents a preset reference time length, D1 represents the similarity, and D2 represents the similarity threshold.
According to the above formula, when the similarity is greater, the time of the mobile terminal entering the first encryption state from the second encryption state is shorter than the time of the duration T2, because the encryption level of the second preset encryption state is higher than the encryption level of the first preset encryption state, the complexity of the encryption password of the second preset encryption state is higher than that of the encryption password of the first preset encryption state, and the decryption is more complex, and if the mobile terminal is an owner user, the similarity is very high, the time of the second preset encryption state is reduced, the faster first preset encryption state today is achieved, the unlocking of the owner user can be more quickly facilitated, and the user experience of the user is improved.
