Abstract

An operation method in an electronic device for mitigating location tracking, and a non-transitory storage medium are provided. The electronic device includes a communication module, a memory and at least one processor electrically connected to the communication module and the memory, wherein the at least one processor is configured to identify a type of at least one executed application, randomly select at least one information element to be included in a frame for wireless communication for the at least one executed application, based on the identified type, generate at least one frame comprising the at least one selected information element, and control the communication module to transmit the at least one generated frame through the wireless communication.

First claim

The invention claimed is:

1. An electronic device comprising:
communication circuitry;
memory; and
at least one processor electrically connected to the communication circuitry and the memory,
wherein the at least one processor is configured to:
identify an application type of at least one executed application,
select a random number of information elements for the application type from among designated random numbers,
randomly select at least one information element to be included in a frame for wireless communication for the at least one executed application,
based on the selected random number of information elements, set a frame body field including the at least one selected information element,
generate at least one frame including the frame body field, and
control the communication circuitry to transmit the at least one generated frame through the wireless communication,

wherein the frame body field consists of a combination of at least one information element, the combination of the at least one information element including the at least one selected information element, and
wherein a frame body field of an application is changed according to an application type of the application.

2. The electronic device of claim 1 , wherein the at least one processor is further configured to randomly select a sequence value to be configured in a sequence control field included in header information of the at least one frame.

3. The electronic device of claim 1 , wherein the at least one generated frame, as a management frame, corresponds to at least one of a probe request frame, an authentication request frame, or an association request frame.

4. The electronic device of claim 1 , wherein the at least one processor is further configured to classify and group the at least one executed application according to the application type, based on at least one of a purpose of an association or a disassociation of a user, or a purpose of location identification.

5. The electronic device of claim 1 , wherein the at least one processor is further configured to:
randomly configure an address information field and a sequence control field included in header information of the at least one frame; and
generate the at least one frame comprising the address information field, the sequence control field, and the frame body field comprising the at least one selected information element.

6. The electronic device of claim 1 , wherein the at least one processor is further configured to randomly select the at least one information element, based on at least one of types of information elements.

7. The electronic device of claim 1 , wherein the at least one processor is further configured to, when the application type of the at least one executed application is identified as a first type having a purpose of an association or a disassociation of a user, select an information element of network address information necessary for the wireless communication and randomly select at least one optional information element from among designated optional information elements.

8. The electronic device of claim 1 ,
wherein the at least one processor is further configured to, when the application type of the at least one executed application is identified as a second type having no purpose of an association or a disassociation of a user and having a purpose of location identification, randomly select at least one optional information element (IE) from among designated optional information elements, and
wherein the at least one selected optional IE is configured with a random value.

9. The electronic device of claim 1 ,
wherein the at least one processor is further configured to, when the application type of the at least one executed application is identified as a third type having neither a purpose of an association or a disassociation of a user nor a purpose of location identification, randomly select at least one optional information element from among designated optional information elements, and
wherein an information element combination comprising the at least one selected optional information element for the third type is different from combinations comprising those for other types, based on at least one of a type of at least one selected option information element and a number of at least one selected option information element.

10. The electronic device of claim 1 , wherein the wireless communication corresponds to wireless communication in a wireless-fidelity (Wi-Fi) communication scheme.

11. The electronic device of claim 1 , wherein the at least one processor is further configured to identify the application type of the at least one executed application in response to detection that transmission of the frame through the wireless communication for the at least one executed application is to occur.

12. A method performed by an electronic device, the method comprising:
identifying an application type of at least one executed application;
selecting a random number of information elements for the identified application type from among designated random numbers;
randomly selecting at least one information element to be included in a frame for wireless communication for the at least one executed application;
based on the selected random number of information elements, setting a frame body field including at least one frame comprising the at least one selected information element;
generating at least one frame including the frame body field; and
transmitting the at least one generated frame through the wireless communication,
wherein the frame body field consists of a combination of at least one information element, the combination of the at least one information element including the at least one selected information element, and
wherein a frame body field of an application is changed according to an application type of the application.

13. The method of claim 12 , further comprising:
randomly selecting a sequence value to be configured in a sequence control field included in header information of the at least one frame.

14. The method of claim 12 , wherein the at least one generated frame, as a management frame, corresponds to at least one of a probe request frame, an authentication request frame, or an association request frame.

15. The method of claim 12 , further comprising:
classifying and grouping the at least one executed application according to the application type, based on at least one of a purpose of an association or a disassociation of a user or a purpose of location identification.

16. The method of claim 12 , further comprising:
randomly configuring an address information field and a sequence control field included in header information of the at least one frame,
wherein the generating of the at least one frame comprises generating the at least one frame comprising the address information field, the sequence control field, and the frame body field comprising the at least one selected information element.

17. The method of claim 12 , wherein the randomly selecting of the at least one information element comprises randomly selecting the at least one information element, based on at least one of the types of information elements.

18. The method of claim 12 , wherein the randomly selecting of the at least one information element comprises, when the application type of the at least one executed application is identified as a first type having a purpose of an association or a disassociation of a user, selecting an information element of network addre
