Abstract

An authentication method using a password of an electronic device is provided. The method includes receiving a password. The method also includes determining whether the received password coincides with a password stored in advance. The method further includes determining whether an input condition at the time of password input coincides with a password input condition stored in advance when the received password coincides with the password stored in advance. The method includes executing a function when the input condition at the time of password input coincides with the password input condition stored in advance.

Claims

1. An authentication method using a password of an electronic device, the method comprising:

receiving a password;

determining whether the received password coincides with a password stored in advance;

determining whether an input condition at a time of password input coincides with a password input condition stored in advance when the received password coincides with the password stored in advance; and

executing a function when the input condition at the time of password input coincides with the password input condition stored in advance.

2. The method of claim 1, further comprising:

deactivating an input field to which the password is input or blocking execution of the function when the input condition at the time of password input does not coincide with the password input condition stored in advance.

3. The method of claim 1, further comprising:

displaying a password error message or requesting a password input retrial when the received password does not coincide with the password stored in advance.

4. The method of claim 1, wherein the password includes at least one of a signature scheme, a personal identification number scheme, and a pattern scheme.

5. The method of claim 4, wherein the password input condition includes an invisible password in addition to the signature scheme, the personal identification number scheme, and the pattern scheme at the time of password input.

6. The method of claim 5, wherein the password input condition includes at least one of a rotation state of the electronic device, a grip state of the electronic device, a password input means, a password input time, a password input place, recognition of a user'"'"'s face, recognition of a user'"'"'s gesture, recognition of a user'"'"'s fingerprint, recognition of user'"'"'s voice, a control environment setting state of the electronic device, a power saving mode state of the electronic device, and a mobile device management (MDM) activation state of the electronic device.

7. The method of claim 1, wherein the function includes at least one of a removal request of a lock screen, switching from an off screen to an on screen, a display request of a home screen provided by the electronic device, an execution request of an application being executed by the electronic device, an execution request of at least one application provided by the electronic device, or an execution request of at least one function of the application being executed by the electronic device.

8. The method of claim 1, further comprising:

setting the password input condition;

storing the set password input condition;

setting the password; and

storing the set password.

9. An electronic device comprising:

a user input unit configured to receive a password from a user;

a memory unit configured to store a password stored in advance and an input condition of the password stored in advance;

a control unit configured to determine whether the received password coincides with the password stored in advance, determine whether an input condition at a time of password input coincides with the input condition of the password stored in advance when the received password coincides with the password stored in advance, and execute a function when the input condition at the time of password input coincides with the input condition of the password stored in advance; and

a display unit configured to display the function executed by the control unit.

10. The electronic device of claim 9, wherein, when the input condition at the time of password input does not coincide with the input condition of the password stored in advance, the control unit is configured to deactivate an input field to which the password is input or block execution of the function.

11. The electronic device of claim 9, wherein, when the received password does not coincide with the password stored in advance, the control unit is configured to display a password error message on the display unit or request a password input retrial.

12. The electronic device of claim 9, wherein the password includes at least one of a signature scheme, a personal identification number scheme, and a pattern scheme.

13. The electronic device of claim 12, wherein the password input condition includes an invisible password in addition to the signature scheme, the personal identification number scheme, and the pattern scheme at the time of password input.

14. The electronic device of claim 13, wherein the password input condition includes at least one of a rotation state of the electronic device, a grip state of the electronic device, a password input means, a password input time, a password input place, recognition of a user'"'"'s face, recognition of a user'"'"'s gesture, recognition of a user'"'"'s fingerprint, recognition of user'"'"'s voice, a control environment setting state of the electronic device, a power saving mode state of the electronic device, and a mobile device management (MDM) activation state of the electronic device.

15. The electronic device of claim 9, wherein the function includes at least one of a removal request of a lock screen, switching from an off screen to an on screen, a display request of a home screen provided by the electronic device, an execution request of an application being executed by the electronic device, an execution request of at least one application provided by the electronic device, or an execution request of at least one function of the application being executed by the electronic device.

16. The electronic device of claim 9, wherein the control unit is configured to set the password input condition, store the set password input condition in the memory unit, set the password, and store the set password in the memory unit.

17. A method of configuring an electronic device for password authentication, the method comprising:

setting a first password input condition;

storing the first password input condition;

setting a first password; and

storing the first password.

18. The method of claim 17, further comprising:

receiving a second password;

determining whether the second password coincides with the first password;

determining whether a second password input condition at a time of receiving the second password coincides with the first password input condition when the second password coincides with the first password; and

executing a function when the second password input condition at the time of receiving the second password coincides with the first password input condition.

19. The method of claim 18, wherein the first password and the second password includes at least one of a signature scheme, a personal identification number scheme, and a pattern scheme.

20. The method of claim 17, wherein the function includes at least one of a removal request of a lock screen, switching from an off screen to an on screen, a display request of a home screen provided by the electronic device, an execution request of an application being executed by the electronic device, an execution request of at least one application provided by the electronic device, or an execution request of at least one function of the application being executed by the electronic device.
