APPARATUS AND METHOD FOR STATISICAL USER AUTHENTICATION USING INCREMENTAL USER BEHAVIOR
First Claim
Patent Images
1. An apparatus for statistical user identification, the apparatus comprising:
- an update unit configured to update a confidence value that statistically represents whether a user is identified as being a user that has permission to use a terminal, based on a user event that occurs when the user manipulates the terminal; and
a statistical authentication unit configured to, in response to a user requesting execution of an application that requests authentication, determine whether to execute the requested application by comparing the confidence value with a reference value that is defined for the requested application.

Abstract
Provided are an apparatus and method for statistical user identification that improves a user'"'"'s convenience while ensuring security. The apparatus may store a confidence value that statistically represents whether a user is identified as a user that has permission to use a terminal, based on a user event that occurs when the user manipulates the terminal. The apparatus may determine whether to execute a user requested application by comparing the confidence value of the user with a reference value that is defined for the requested application.

10. A method of statistical user identification, the method comprising:
-
updating a confidence value that statistically represents whether a user is identified as being a user that has permission to use a terminal, based on a user event that occurs when the user manipulates the terminal; and upon occurrence of a user event requesting execution of an application that requests authentication, determining whether to execute the requested application by comparing the confidence value with a reference value that is defined for the requested application. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A method for statistical user identification, the method comprising:
-
detecting a user event that occurs when a user manipulates a terminal; comparing feature information of the detected user event with feature event of a user model and updating a confidence value that statistically represents whether a user has permission to use the terminal, based on a comparison result of the feature information; determining whether the detected user event is a user event requesting execution of an application which is executable in the terminal and which requests authentication; and determining whether to execute the application by comparing the updated confidence value with a reference value that is a previously defined for each application, if the detected user event is the user event requesting execution of the application. - View Dependent Claims (18)

19. A terminal for statistical identification of a user that manipulates the terminal, the terminal comprising:
-
a storage unit configured to store a confidence value that statistically represents whether the user has permission to use a respective application; and a statistical authentication unit configured to determine whether the user has permission to execute a requested application by comparing the user'"'"'s confidence value with a reference value that is defined for the requested application. - View Dependent Claims (20, 21, 22, 23, 24)
