When the computing device 200 receives a request to unlock the mobile terminal, the computing device 200 will request its identity code from the target mobile terminal 100, and the target mobile terminal 100 transmits its identity code to the computing device 200, and the computing device 200 will receive the The identity code of the target mobile terminal 100 detects whether the identity code of the target mobile terminal 100 is stored in the identity codes of the plurality of mobile terminals stored in the password recording module 210. If found, the target mobile terminal 100 is listed in the password recording module. In the stored list of unlockable mobile terminals, the password recording module 210 obtains the universal screen lock password from the password record module 210 and encrypts it, and transmits the encrypted universal screen lock password to the unlock module 120 through the data transmission channel. .

The unlocking module 120 receives the universal screen lock password data sent by the computing device 200, decrypts the universal screen lock password, and then transmits the decrypted universal screen lock password to the screen lock module 130 to perform screen unlock processing using the universal screen lock password. .

Through this encryption mechanism, the security of data communication between the computing device 200 and the target mobile terminal 100 is improved, ensuring that the target mobile terminal 100 only processes unlock commands that can be authenticated by encryption.

The screen lock module 130 is used to set the screen lock of the mobile terminal. When the target mobile terminal 100 is in the screen lock state, the target mobile terminal 100 is unlocked only by inputting the unlock password or receiving the unlock command sent by the unlocking module 120, so that the target mobile terminal 100 returns to the normal use state.
