A mobile terminal unlock method for security protection, comprising:
- obtaining a trigger signal for unlock, and entry of an unlock password when the mobile terminal is in a lock out state;
- generating an unlock signal according to a preset correspondence between the unlock signal and a first password, and sending the corresponding unlock signal, wherein, when generating the first password, the mobile terminal generates corresponding vibration signals according to a preset correspondence between vibration signals and the first password, the first password containing characters, wherein a mobile terminal user presets a vibration mode in which the corresponding vibration signals correspond to characters that form the first password, wherein according to the corresponding vibration signals, the user determines characters for the entry of the unlock password of the mobile terminal after a parsing of the corresponding vibration signals;
- matching the unlock password with the first password;
- determining whether the unlock password is consistent with the first password;
- and
- when a determining result is yes, unlocking a password lock;
- or
- when a determining result is no, obtaining a trigger signal for unlock again;
- wherein the method further comprises:
- when a quantity of times of obtaining the trigger signal for unlock exceeds a maximum quantity of unlock error times, enabling a global positioning system GPS, obtaining positioning data of a mobile terminal, sending the positioning data to a mailbox bound to the mobile terminal, so that a user can track a location of the mobile phone according to information about the positioning data after obtaining the positioning data, and stopping obtaining the trigger signal for unlock within a specified time, wherein the maximum quantity of unlock error times is a total quantity of times that the mobile terminal user is allowed to enter an incorrect password and that is preset by the mobile terminal user, and the specified time is a time for which the mobile terminal is automatically locked after an unlock failure and that is preset by the mobile terminal user;
- wherein the preset correspondence between the unlock signal and the first password comprises a one-to-one correspondence, preset by the user and stored in the mobile terminal, between the unlock signal and the first password, wherein the first password contains at least one type of character:
- a digit, a letter, or a symbol.
