Abstract

An electronic device is provided. The electronic device includes a communication module, memory, including one or more storage media, storing instructions, a display, and a processor communicatively coupled to the communication module, the memory, and the display, wherein the instructions, when executed by the processor, cause the electronic device to receive, through the communication module, identification information related to a stylus pen from the stylus pen, in response to a first input of the stylus pen, based on authentication information corresponding to the identification information stored in the memory, display an authentication screen for authenticating the stylus pen, receive, through the authentication screen, a second input of the stylus pen, and based on authentication being met based on the authentication information and the second input, provide content corresponding to the authentication information.

First claim

What is claimed is:

1 . An electronic device comprising:
a communication module; memory storing instructions; a display; and a processor communicatively coupled to the communication module, the memory, and the display; wherein the instructions, when executed by the processor, cause the electronic device to:
receive, through the communication module, identification information related to a stylus pen from the stylus pen,
in response to a first input of the stylus pen, based on authentication information corresponding to the identification information stored in the memory, display an authentication screen for authenticating the stylus pen,
receive, through the authentication screen, a second input of the stylus pen, and
based on authentication being met based on the authentication information and the second input, provide content corresponding to the authentication information.

2 . The electronic device of claim 1 ,
wherein the content corresponding to the authentication information is copied content among at least one content displayed on a display included in an external electronic device, based on a third input of the stylus pen input to the display included in the external electronic device, and wherein the instructions, when executed by the processor, further cause the electronic device to, in response to the first input for pasting the copied content to the display of the electronic device, display the authentication screen.

3 . The electronic device of claim 2 , wherein the content corresponding to the authentication information includes a clipboard corresponding to the authentication information.

4 . The electronic device of claim 3 , wherein the instructions, when executed by the processor, further cause the electronic device to store content related to a fourth input received by the stylus pen after the authentication is met, in association with the authentication information.

5 . The electronic device of claim 3 , wherein the instructions, when executed by the processor, further cause the electronic device to, based on the authentication being not met, store content related to a third input received by the stylus pen after the authentication is not met, in association with the electronic device.

6 . The electronic device of claim 5 , wherein the authentication information is set at a time of initial connection with the stylus pen through the communication module, mapped to the identification information, and stored in the memory.

7 . The electronic device of claim 6 , wherein the instructions, when executed by the processor, further cause the electronic device to maintain a pen setting value including at least one of a pen color, a pen thickness, or a pen type of the stylus pen, which is set in an external electronic device before connection with the electronic device, based on at least one of the identification information or the authentication information.

8 . The electronic device of claim 7 , wherein the instructions, when executed by the processor, further cause the electronic device to, based on authentication of first authentication information among a plurality of pieces of authentication information corresponding to the identification information being met based on the second input, provide first content corresponding to the first authentication information.

9 . The electronic device of claim 8 , wherein the instructions, when executed by the processor, further cause the electronic device to, based on communication with a plurality of stylus pens through the communication module, receive an input from each of the plurality of stylus pens through the display.

10 . The electronic device of claim 9 , wherein the instructions, when executed by the processor, further cause the electronic device to, based on identification information about each of the plurality of stylus pens, distinguish and display the input received from each of the plurality of stylus pens, for each stylus pen.

11 . The electronic device of claim 10 , wherein the instructions, when executed by the processor, further cause the electronic device to, based on the identification information about each of the plurality of stylus pens, generate the input received from each of the plurality of stylus pens as separate layers distinguished for each stylus pen.

12 . A method for controlling an electronic device, the method comprising:
receiving identification information related to a stylus pen from the stylus pen; in response to a first input of the stylus pen, based on authentication information corresponding to the identification information stored in memory of the electronic device, displaying an authentication screen for authenticating the stylus pen; receiving, through the authentication screen, a second input of the stylus pen; and based on authentication being met based on the authentication information and the second input, providing content corresponding to the authentication information.

13 . The method of claim 12 ,
wherein the content corresponding to the authentication information is copied content among at least one content displayed on a display included in an external electronic device, based on a third input of the stylus pen input to the display included in the external electronic device, and wherein displaying the authentication screen includes, in response to the first input for pasting the copied content to the display of the electronic device, displaying the authentication screen.

14 . The method of claim 13 , wherein the content corresponding to the authentication information includes a clipboard corresponding to the authentication information.

15 . The method of claim 14 , further comprising:
storing content related to a fourth input received by the stylus pen after the authentication is met, in association with the authentication information.

16 . One or more non-transitory computer-readable storage media storing one or more computer programs including computer-executable instructions that, when executed by a processor of an electronic device, cause the electronic device to perform operations, the operations comprising:
receiving identification information related to a stylus pen from the stylus pen; in response to a first input of the stylus pen, based on authentication information corresponding to the identification information stored in memory of the electronic device, displaying an authentication screen for authenticating the stylus pen; receiving, through the authentication screen, a second input of the stylus pen; and based on authentication being met based on the authentication information and the second input, providing content corresponding to the authentication information.

17 . The one or more non-transitory computer-readable storage media of claim 16 ,
wherein the content corresponding to the authentication information is copied content among at least one content displayed on a display included in an external electronic device, based on a third input of the stylus pen input to the display included in the external electronic device, and wherein displaying the authentication screen includes, in response to the first input for pasting the copied content to the display of the electronic device, displaying the authentication screen.

18 . The one or more non-transitory computer-readable storage media of claim 17 , wherein the content corresponding to the authentication information includes a clipboard corresponding to the authentication information.

19 . The one or more
