Abstract: An application-executing method using fingerprint recognition includes obtaining an image of a first fingerprint through a fingerprint sensor and recognizing the first fingerprint, executing a first application corresponding to the first fingerprint in a first screen when the first fingerprint is recognized, obtaining an image of a second fingerprint through the fingerprint sensor and recognizing the second fingerprint, determining whether the second fingerprint is recognized within a predetermined time after the first application is executed, and, based on a determination result, when it is determined that the second fingerprint is recognized within the predetermined time after the first application is executed, generating a second screen by splitting the first screen, and executing the first application on one of the second screen, and a second application corresponding to the second fingerprint on the other of the second screen.

Abstract: Provided are a method, apparatus, and computer-readable recording medium for conveniently recognizing a fingerprint. A fingerprint recognition method according to an embodiment of the present invention includes: checking a position-state of a fingerprint sensing unit to set a flag value; collecting a plurality of fingerprint image segments sequentially acquired by the fingerprint sensing unit; and changing a matching order of the fingerprint image segments according to the flag value to perform the fingerprint recognition.

Abstract: An application-executing method using fingerprint recognition wherein an application-executing device executes an application using fingerprint recognition, includes recognizing a fingerprint from a fingerprint image obtained through a fingerprint sensor in a locking state of the application-executing device, activating a specific area that is part of a locking state screen of the application-executing device when the fingerprint is recognized, displaying a list of a plurality of applications in the specific area, receiving selection information of at least one application from the list of the plurality of applications, and executing an application according to the selected information.

Abstract: Provided are a method of restricting the use of a file, an electronic device, and a recording medium. The method of restricting the use of the file includes receiving an input of setting a region by a touch drag operation or a touch draw operation on a screen, receiving an input of a fingerprint of a user, and setting a lock on at least one file included in the region by matching the at least one file and the input of the fingerprint.

Abstract: Provided are a method of displaying a message using a fingerprint, a user terminal, and a recording medium. The method includes displaying message reception notification of a received message in a screen lock state, sensing an input fingerprint so as to confirm the received message, and displaying the message while maintaining the screen lock state when the sensed fingerprint is authenticated.

Abstract: Provided are a user terminal having an enhanced privacy protection function, a method of using a lock function of the user terminal, and a computer-readable recording medium. The user terminal includes a lock function executing unit that receives an execution command from a service server to execute a lock function, a fingerprint input displaying unit that displays a fingerprint input requesting window when an operation command is input, a fingerprint sensor unit that receives fingerprint information, and a lock function releasing unit that releases the lock function when the fingerprint information input through the fingerprint sensor unit is identified with preregistered fingerprint information.
