Abstract

A method for providing a security function includes obtaining a request for executing a function of application through an electronic device if the electronic device is located within a predetermined distance from a user, identifying a success or failure of a first authentication which is previously performed for the user in response to the request, and determining whether to perform a second authentication for executing the function of the application based on the success or failure of the first authentication, wherein determining whether to perform the second authentication comprises performing the second authentication by using a security level lower than a security level related to the first authentication if the success of the first authentication is identified. An electronic device includes a processor configured to determine a success or failure of a first authentication, and decide whether to perform a second authentication with a second security level for executing the function.

Claims

1. A method comprising:

obtaining a request for executing a function of application through an electronic device if the electronic device is located within a predetermined distance from a user;

identifying success or failure of a first authentication which is previously performed for the user, in response to the request; and

determining whether to perform a second authentication for executing the function of the application based on the success or failure of the first authentication,

wherein determining whether to perform the second authentication comprises performing the second authentication by using a security level lower than a security level related to the first authentication if the success of the first authentication is identified.

2. The method of claim 1, further comprising determining whether the electronic device is located within the predetermined distance from user, by using information detected through a sensor operatively coupled to the electronic device.

3. The method of claim 1, wherein the first authentication is performed when the electronic device is located within the predetermined distance from user.

4. The method of claim 3, wherein the electronic device remains within the distance from the user after the first authentication is performed.

5. The method of claim 1, wherein identifying the success or failure of the first authentication comprises receiving the success or failure of the first authentication from an external device for the electronic device.

6. The method of claim 1, wherein the first authentication is performed in an external device when a distance between the electronic device and the external device is within a specified range.

7. The method of claim 1, wherein performing the second authentication comprises performing the second authentication by using a security level higher than or equal to the security level related to the first authentication if the failure of the first authentication is identified.

8. The method of claim 1, wherein performing the second authentication comprises:

comparing a security level assigned to the function with the security level related to the first authentication; and

if the assigned security level is higher than or equal to the security level related to the first authentication and the success of the first authentication is identified, performing the second authentication by using the assigned security level.

9. The method of claim 8, wherein performing the second authentication comprises adjust ing the assigned security level to be lower than the security level related to the first authentication if the assigned security level is lower than the security level related to the first authentication.

10. The method of claim 1, further comprising executing the function without performing the second authentication if the first authentication is successful.

11. The method of claim 1, further comprising:

determining whether the electronic device is worn on a user; and

determining a security level assigned to the electronic device in response to the electronic device being worn on the user.

12. The method of claim 11, further comprising receiving an input whether to adjust the assigned security level from the user, when the electronic device is worn on the user for a time.

13. The method of claim 11, further comprising:

receiving an input whether to change the assigned security level from the user when the electronic device is detached from the user; and

resetting the assigned security level unless the input is received from the user.

14. The method of claim 13, further comprising setting the security level assigned to the electronic device to a security level specified before wearing again or to the reset security level, when the electronic device is worn by the user again.

15. An electronic device comprising:

a processor configured to;

obtain a request for executing a function of application through the electronic device, if the electronic device is located within a predetermined distance from a user;

identify a success or failure of a first authentication which is previously performed for the user, in response to the request; and

determine whether to perform a second authentication for executing the function based on the success or failure of the first authentication,

wherein the processor is configured to perform the second authentication by using a security level lower than a security level related to the first authentication when the success of the first authentication is identified.

16. The electronic device of claim 15, wherein the electronic device is worn on the user.

17. The electronic device of claim 15, wherein the processor is configured to receive the success or failure from an external device for the electronic device.

18. The electronic device of claim 15, wherein the processor is configured to obtain the success or failure of the first authentication which is performed in an external electronic device when the electronic device and the external device for the electronic device are paired.

19. The electronic device of claim 15, wherein the processor is configured to perform the second authentication by using the low security level in response to the success of the first authentication when the electronic device and an external device are paired.

20. The electronic device of claim 15, wherein the processor is configured to perform the second authentication by using a security level higher than or equal to the security level related to the first authentication if the failure of the first authentication is identified.
