Abstract

An apparatus and method in a portable terminal for an integrated login input are provided. The integrated login input method includes, displaying a plurality of images during registration of a password, displaying a plurality of images, selecting one of the plurality of displayed images, determining a coordinate system according to an encryption level to be set for the password and applying the determined coordinate system to the selected image, changing a tilt of the portable terminal by an angle and detecting the changed tilt, receiving a selection of the user on a region of the selected image, and combining the detected tilt and coordinates corresponding to the region where the user'"'"'s selection is generated and registering the combination as the password.

Claims

1. An integrated login input method in a portable terminal, the method comprising:

displaying a plurality of images during registration of a password;

selecting one of the plurality of displayed images;

determining a coordinate system according to an encryption level to be set for the password and applying the determined coordinate system to the selected image;

changing a tilt of the portable terminal by an angle and detecting the changed tilt;

receiving a selection of the user on a region of the selected image; and

combining the detected tilt and coordinates corresponding to the region where the user'"'"'s selection is generated and registering the combination as the password.

2. The method of claim 1, wherein the coordinate system comprises at least one of a Cartesian coordinate system, a cylindrical coordinate system, a spherical coordinate system, and a toroidal coordinate system.

3. The method of claim 1, wherein the coordinate system applied to the image is such that coordinates of the coordinate system change with the tilt of the portable terminal.

4. The method of claim 1, wherein the coordinates corresponding to the region where the user'"'"'s selection is generated are acquired by applying a filter to the coordinate system according to tilts along three axes including an x axis, a y axis, and a z axis in the angle.

5. The method of claim 1, wherein the receiving of the selection of the user comprises receiving a tapping on a touch screen of the portable terminal.

6. The method of claim 1, further comprising, activating an auto-fill function during input of information after driving an Application Programming Interface (API) of a program to which login is to be performed.

7. The method of claim 1, wherein the displaying of the plurality of images is performed during registration of a password due to joining of a particular Social Networking Service (SNS) and further wherein the registering of the combination as the password comprises registering the combination as the password for the SNS.

8. The method of claim 1, further comprising,

determining whether a password has already been stored when driving an Application Programming Interface (API) of a program to be executed;

if the password has already been stored, displaying the image, to which the coordinate system is applied, on a display screen of the portable terminal;

determining a change in the tilt of the portable terminal;

comparing the changed tilt with the tilt stored during registration of the password, and, if they match, receiving a user'"'"'s selection on a region of the displayed image; and

if the user'"'"'s selection matches coordinates input by the user during registration of the password, logging in to the program to be executed.

9. The method of claim 8, wherein the program comprises a Social Networking Service (SNS).

10. The method of claim 8, further comprising using an auto-fill function of an IDentification (ID) and a password at the time of login to the program.

11. The method of claim 1, wherein the tilt of the portable terminal is perpendicular to an enlargement or reduction rate of the image.

12. The method of claim 8, wherein the determining of the change of the tilt comprises applying a weight value to the filter-applied coordinates system applied to the image as the tilt of the portable terminal increases from 0 degrees.

13. The method of claim 12, wherein, when the portable terminal is positioned perpendicular to the ground, the tilt of the portable terminal is measured as 0 degrees.

14. An integrated login input apparatus in a portable terminal, the apparatus comprising:

a tilt sensor for acquiring a tilt according to a tilt state of the portable terminal; and

a controller for applying a coordinate system to an image selected through a display unit of the portable terminal on the display unit, for detecting the tilt acquired by the tilt sensor and coordinates corresponding to a region of the displayed image selected by a user, for combining the tilt and the coordinates to store the combination as a password, and for performing an auto-fill function with a value stored in the memory when driving an Application Programming Interface (API) of a program to be executed.

15. The apparatus of claim 14, wherein the coordinates are acquired by applying a weight value to a filter-applied coordinate system applied to the image as the tilt of the portable terminal increases.

16. The apparatus of claim 14, wherein the controller registers the password in the same manner when the password is forgotten.

17. The apparatus of claim 14, wherein the coordinate system comprises at least one of a Cartesian coordinate system, a cylindrical coordinate system, a spherical coordinate system, and a toroidal coordinate system.

18. The apparatus of claim 14, wherein the coordinate system applied to the image is such that coordinates of the coordinate system change with the tilt of the portable terminal.

19. The apparatus of claim 14, wherein the coordinates corresponding to the region where the user'"'"'s selection is generated are acquired by applying a filter to the coordinate system according to tilts along three axes including an x axis, a y axis, and a z axis in the angle.

20. The apparatus of claim 14, further comprising a touch screen, wherein the controller detects the selection of the user by receiving a tapping on the touch screen.

21. The apparatus of claim 14, wherein the controller activates an auto-fill function during input of information after driving an Application Programming Interface (API) of a program to which login is to be performed.

22. The apparatus of claim 14, wherein the combining of the tilt and the coordinates to store the combination as a password comprises storing the combination as a password for a Social Networking Service (SNS) and further wherein the API is driven for the SNS as the program to be executed.
