Abstract

The present invention relates to a mobile terminal capable of user identification based on artificial intelligence technology. The present invention includes an artificial intelligence unit for generating a usage pattern related to an operation performed on the mobile terminal and generate a control command for executing any one of a plurality of operation modes having different security standards based on the generated usage pattern, and a control unit for executing any one of the plurality of operation modes in response to a control command generated by the artificial intelligence unit. The artificial intelligence unit monitors situation information regarding an operation performed on the mobile terminal, compares the generated payment pattern with the monitored situation information, and generates a control command for executing any one operation mode based on a comparison result.

First claim

What is claimed is:

1. A mobile terminal, comprising:
a memory configured to store a plurality of functions of the mobile terminal; and
a controller configured to:
learn a usage pattern of a legitimate user for a specific function by monitoring user patterns that include first input associated with the legitimate user occurring during different operation states, wherein the operation states include a specific state and a state in which an input for executing the specific function is to be received,
set the usage pattern of the legitimate user as a pre-learned pattern corresponding to the specific function,
determine whether a first user is the legitimate user based on a comparison of an input pattern with the pre-learned pattern, wherein the input pattern includes second input associated with the first user occurring during the operation states,
execute the specific function in a first mode having a first security standard when the first user is determined to be the legitimate user, and
execute the specific function in a second mode having a second security standard higher than the first security standard when the first user is determined to not be the legitimate user.

2. The mobile terminal of claim 1 , further comprising:
a touch sensor configured to detect a touch, wherein the first input includes a plurality of touch inputs detected by the touch sensor.

3. The mobile terminal of claim 2 , wherein the controller is further configured to:
analyze a touch area of the touch inputs, a touch pressure of the touch inputs, a touch speed of the touch inputs, information on a finger applying the touch inputs, the number of touches of the touch inputs, or touch type of the touch inputs.

4. The mobile terminal of claim 1 , wherein the second mode is a mode in which an operation related to some of a plurality of menus related to the specific function is limited.

5. The mobile terminal of claim 4 , wherein the controller is further configured to:
output notification information for requesting additional authentication when an execution request for an operation related to the limited menus is received.

6. The mobile terminal of claim 5 , wherein the controller is further configured to:
execute the operation related to the limited menus when the additional authentication is performed.

7. The mobile terminal of claim 1 , wherein:
the mobile terminal operates in any one state of a locked state and a released state, wherein the locked state is where an operation of the mobile terminal is limited according to a user input and the released state is where operation control of the mobile terminal is available according to a user input; and
wherein the controller is further configured to:
select any one of a plurality of operation modes having different security levels based on user input applied during the locked state, the selecting occurring when the locked state is switched to the released state based on the user input applied during the locked state.

8. The mobile terminal of claim 1 , wherein the pre-learned pattern further includes a number of times of the first input, an input type of the first input, or an input method of the first input.

9. The mobile terminal of claim 1 , further includes an artificial intelligence processor, wherein the artificial intelligence processor is configured to:
extract common components and difference components from a plurality of usage patterns, and classify a plurality of usage patterns based on the extracted common components and difference components; and
determine whether the first user has legitimate rights by calculating a probability corresponding to execute the specific function by the legitimate user for each extracted common component,
wherein the controller is further configured to execute the specific function in any one of a plurality of operation modes having different security levels based on the determination result,
wherein the artificial intelligence processor is further configured to:
assign different weights to each of the common components;
learn a payment pattern by combining the common components having the different assigned weights;
compare monitored information including at least one of information regarding an input pattern of the payment related control signals and surrounding environment of the mobile terminal at a time of the payment with the learned payment pattern; and
determine whether the payment is executed under a normal payment situation based on the comparison result,
wherein the information regarding the surrounding environment of the mobile terminal at the time of the payment includes at least one of location information, time information, card information of the payment, payment amount information, and payment item information.

10. The mobile terminal of claim 9 , wherein the artificial intelligence processor is further configured to:
detect that a specific item is paid more than a predetermined number of times within a specific time period in a specific place;
identify the specific item in the specific place within the specific time period as the common components; and
assign different weights to each of the specific item, the specific place and the specific time period as the common components.
