Abstract

An authentication method of an electronic device is disclosed. A plurality of key inputs is received from a user via activation of input keys. At least one key input from the key inputs is validated based on a predefined criterion to obtain a password. The password is compared to a registered password to obtain an authenticated password.

Claims

1. An electronic device, comprising:

an operational module comprising a plurality of input keys;

a control module operable to perform authentication by;

receiving a plurality of key inputs from a user via activation of the input keys;

validating at least one key input from the key inputs based on a predefined criterion to obtain a password; and

comparing the password to a registered password.

2. The electronic device according to claim 1, further comprising a memory module operable to store the registered password.

3. The electronic device according to claim 1, further comprising a display module operable to display an input mark in response to activation of each of the input keys regardless of whether the predefined criterion is met.

4. The electronic device according to claim 1, wherein the predefined criterion is based on a relationship between the at least one key input and an input to an input module.

5. The electronic device according to claim 1, wherein the control module is further operable to invalidate the at least one key input, if an input key associated with the at least one key input is activated.

6. The electronic device according to claim 4, further comprising a housing, wherein the input keys and the input module are located on different surfaces of the housing from each other.

7. The electronic device according to claim 1, wherein the predefined criterion is met, if the input key associated with the at least one key input is activated while a displayed object is displayed on a display module.

8. The electronic device according to claim 1, wherein the predefined criterion is met, if at least one of the input keys is continuously activated.

9. An electronic device, comprising:

a housing;

a plurality of input keys located on a front surface of the housing;

a side key located on a side surface of the housing;

a memory module operable to store a registered password; and

a control module operable to perform an authentication by;

receiving a plurality of key inputs from a user via activation of the input keys;

validating at least one key input from the key inputs to obtain a password, if the side key is not activated before receiving the at least one key input; and

comparing the password to the registered password to obtain an authenticated password.

10. An authentication method of an electronic device comprising:

receiving a plurality of key inputs from a user via activation of input keys;

validating at least one key input from the key inputs based on a predefined criterion to obtain a password; and

comparing the password to a registered password.

11. The method of claim 10, further comprising displaying an input mark in response to activation of each of the input keys regardless of whether the predefined criterion is met.

12. The method of claim 10, wherein the predefined criterion is based on a relationship between the at least one key input and an input to an input module.

13. The method of claim 10, wherein the predefined criterion comprises invalidating the at least one key input, if an input key associated with the at least one key input is activated.
