Electronic device and operation method thereof

1. A method of operating an electronic device, the method comprising:

obtaining dynamic biometric data regarding a movement of a user, wherein the movement of the user indicates an identity of the user;

identifying joint angles of the user that change over a period of time due to the movement of the user;

modifying the dynamic biometric data of the movement of the user, the modification changes a value of one of the joint angles at certain time intervals for removing an identifier included in the dynamic biometric data and de-identifies the identity of the user by preventing the user from being identified based on the movement, wherein the modified dynamic biometric data is for reconstructing a distorted movement of the user; and

transmitting the modified dynamic biometric data to a server for providing a service based on the modified dynamic biometric data.

2. The method of claim 1 , further comprising reconstructing the distorted movement of the user based on the modified dynamic biometric data.

3. The method of claim 2 , wherein the value of the dynamic biometric data is modified such that the reconstructed distorted movement is not unnatural while not able to identify the user.

4. The method of claim 1 , wherein the value of the dynamic biometric data is modified to a value greater than an error rate of the obtained dynamic biometric data at a time of obtaining the dynamic biometric data.

5. The method of claim 2 , wherein the value of the dynamic biometric data is modified such that a continuity of the reconstructed distorted movement of the user is maintained.

6. The method of claim 1 , wherein modifying the value of the dynamic biometric data comprises differently modifying the value of the dynamic biometric data over time.

7. The method of claim 1 , further comprising receiving an input from the user as to whether to perform the de-identification,

wherein de-identifying the dynamic biometric data comprises de-identifying the dynamic biometric data of the user when receiving, from the user, an input for de-identifying the dynamic biometric data.

8. The method of claim 7 , further comprising transmitting the dynamic biometric data to the server without de-identifying the dynamic biometric data, in response to receiving, from the user, an input for not de-identifying the dynamic biometric data or when there is no user input for de-identifying the dynamic biometric data.

9. The method of claim 1 , wherein obtaining the dynamic biometric data regarding the movement of the user comprises receiving, from an external device, the dynamic biometric data obtained by the external device.

10. The method of claim 1 , wherein obtaining the dynamic biometric data regarding the movement of the user comprises capturing the movement of the user.

11. The method of claim 1 , wherein obtaining the dynamic biometric data regarding the movement of the user comprises sensing the movement of the user.

12. The method of claim 1 , further comprises, receiving from the server a service for displaying the movement of the user based on the distorted movement of the user.

13. An electronic device comprising:

a communicator;

a memory configured to store a program for performing an operation of the electronic device; and

a processor configured to:

obtain dynamic biometric data regarding a movement of a user, wherein movement of the user indicates an identity of the user;

identify joint angles of the user that change over a period of time due to the movement of the user;

modify the dynamic biometric data of the movement of the user, the modification changes a value of one of the joint angles at certain time intervals for removing an identifier included in the dynamic biometric data and de-identifies the identity of the user by preventing the user from being identified based on the movement, wherein the modified dynamic biometric data is for reconstructing a distorted movement of the user; and

transmit the modified dynamic biometric data to a server for providing a service based on the modified dynamic biometric data.

14. The electronic device of claim 13 , wherein the processor is further configured to reconstruct the distorted movement of the user based on the modified dynamic biometric data.

15. The electronic device of claim 13 , further comprising an input unit configured to receive an input from the user as to whether to perform the de-identification,

wherein the processor is further configured to de-identify the dynamic biometric data of the user when receiving, from the user, an input for de-identifying the dynamic biometric data.

16. A method of operating a server, the method comprising:

receiving dynamic biometric data regarding a movement of a user, wherein the movement of the user indicates an identity of the user;

identifying joint angles of the user that change over a period of time due to the movement of the user;

modifying the dynamic biometric data of the movement of the user, the modification changes a value of one of the joint angles at certain time intervals for removing an identifier included in the dynamic biometric data and de-identifies the identity of the user by preventing the user from being identified based on the movement, wherein the modified dynamic biometric data is for reconstructing a distorted movement of the user; and

providing a service based on the modified dynamic biometric data.

17. The method of claim 16 , further comprising reconstructing the distorted movement of the user based on the modified dynamic biometric data.

18. The method of claim 16 , wherein the service is for displaying the movement of the user based on the modified dynamic biometric data.

19. A server comprising:

a communicator;

a memory configured to store a program for performing an operation of the server; and

a processor configured to:

obtain dynamic biometric data regarding a movement of a user, wherein the movement of the user indicates an identity of the user,

identify joint angles of the user that change over a period of time due to the movement of the user,

modify the dynamic biometric data of the movement of the user, the modification changes a value of one of the joint angles at certain time intervals for removing an identifier included in the dynamic biometric data and de-identifies the identity of the user by preventing the user from being identified based on the movement, wherein the modified dynamic biometric data is for reconstructing a distorted movement of the user, and

provide a service based on the modified dynamic biometric data.

20. The server of claim 19 , wherein the processor is further configured to reconstruct the distorted movement of the user based on the modified dynamic biometric data.
