The following are specific steps of implementing terminal unlocking in this embodiment:
step S10, the terminal receives the light signal transmitted by the light-emitting device through the built-in photosensitive device, and extracts the unlocking information from the light signal;

step A, determining an application associated with a data password according to a preset association relationship between the data password and the application;
and B, starting the application associated with the data password.

And if one of the pre-stored data passwords is detected to be matched with the data password corresponding to the unlocking information, inquiring an application associated with the matched data password, and directly starting the application so as to provide the user with the application.
Further, in order to improve the accuracy of application start, the terminal may execute the steps a to B only when the application start function is started in the setting condition of the terminal.
For a better understanding of the present embodiment, the following are exemplified:
referring to fig. 6, after the terminal executes an unlocking operation and displays an unlocked system main interface in the terminal interface, each application icon is displayed on the system main interface, at this time, the terminal checks whether the data password of the unlocking information is matched with a pre-stored data password, and then judges an application associated with the pre-stored data password to determine the application associated with the data password of the unlocking information, if the application associated with the data password of the unlocking information is an audio application, the terminal can directly start the data password audio application to play audio, for example, playing a song of ten years.
In this embodiment, equivalently, under the condition that the optical signal is successfully unlocked, if the data password included in the optical signal corresponds to the application in the terminal, direct start of the application can be realized, so that convenience in terminal unlocking and application start is realized, repeated operation is not needed, and convenience and intelligence in terminal use are improved.

step C, determining the application related to the optical frequency information according to the incidence relation between the preset optical frequency information and the application;
and D, starting the application related to the optical frequency information.
