When the user's input is interrupted for a predetermined time, the terminal 200 switches the state to the lock mode as shown in a) of FIG. 3.

In the lock mode state, when a user's fingerprint input is detected through the fingerprint recognition module 120 (S10), the controller 140 first drives the fingerprint recognition module 120 to detect the user's fingerprint. . In operation S20, fingerprint identification information is extracted from the detected fingerprint of the user. When the fingerprint identification information is extracted, the user information DB 130 is searched to detect user information that matches the extracted identification information. (S40)

In operation S40, when user information that matches the fingerprint identification information is detected (S50), the terminal 200 is switched to an operation mode and a recommended menu screen corresponding to the identification information is illustrated in FIG. 5. Output to display 110. (S60-S70)

In the process S10, a user who attempts a fingerprint input may be classified into three cases. i) when a user (main user) directly inputs a fingerprint; ii) a user who is stored in the DB 130 enters a fingerprint; and iii) a user who is not stored in the DB 130 It may be divided into a case of inputting a fingerprint.

i) First, when the user who inputs the fingerprint is the user, that is, the main user, the controller 140 switches the terminal 200 to the operation mode (S60), and the recommendation engine 150 uses the terminal 200. The basic menu screen provided by is displayed on the terminal as it is. (S70)

ii) If the user who inputs the fingerprint is the user (eg, daughter (5 years old)) of the user stored in the DB 130, the controller 140 switches the terminal 200 to the operation mode (S60). The recommendation engine 150 outputs a recommendation menu preset by the user to the display 110. If there is no recommendation menu preset by the user, the recommendation engine 150 transmits the user information detected by the DB 130 to the recommendation server 300. In addition, the recommendation menu provided from the recommendation server 300 is output to the display 110. 5B shows a menu screen provided from the recommendation server 300 on the terminal.

iii) In addition, if the user who inputs the fingerprint is a user's periphery that is not stored in the DB 130, the controller 140 outputs a predetermined information input window to the display 110 to display user information from the user. Get input. In operation S90, the input user information is transmitted to the recommendation server 300, and the terminal 200 is switched to the operation mode. (S60)

The recommendation engine 150 transmits the received user information (for example, the user's name, age, gender, interests, etc.) to the recommendation server 300, receives a recommendation menu screen, and displays the recommendation menu on the terminal. (S70)

Through the above processes (S10 ~ S70), the locked terminal 200 is switched to the operation mode, and displays the recommended menu screen. And, once, the terminal 200 is switched to the operation mode is connected to the recommendation server 300 and transmits the information of the current user. (S80)

When the user information is received from the terminal 200, the recommendation server 300 selects contents suitable for the user, that is, customized contents (eg, an app) or information according to the gender, age, and interest of the user, and thus the terminal ( 200). In addition, the recommendation engine 150 of the terminal that receives the customized content (for example, an app) from the recommendation server 300 executes the content provided from the server 300 according to a user's approval or selection, or stores it in a memory. Save it. (S80)

When someone tries to unlock the terminal by inputting a fingerprint, the controller 140 automatically photographs the user and stores the photographed image in a predetermined memory space in the terminal 200 as a connection history. By checking the stored connection history, the main user of the terminal 200 can determine which users have attempted to access and attempt to unlock the terminal.

The user-customized service system in the mobile terminal 200 described above may be implemented in hardware or may be implemented in an app.
