5. The electronic device of claim 2 , wherein the instructions, when executed by the at least one processor individually or collectively, further cause the electronic device to:
based on the content including a background, determine whether a difference between a brightness of information other than the background and a brightness of the background is equal to or greater than a set value, and
based on the difference between the brightness of the information and the brightness of the background being less than the set value, identify a brightness different from the brightness of the background, with a difference within a set range, as the brightness of the object.
6. The electronic device of claim 1 , wherein the instructions, when executed by the at least one processor individually or collectively, further cause the electronic device to:
based on at least one of a color or a brightness of the content being changed, change at least one of the color or the brightness of the object in real time based on the changed at least one of the color or the brightness of the content.
7. The electronic device of claim 1 , wherein the instructions, when executed by the at least one processor individually or collectively, further cause the electronic device to:
based on a type of the content being a video, determine the color of the object as an achromatic color, and
change the brightness of the object in real time in each frame of the video.
8. The electronic device of claim 1 , wherein the instructions, when executed by the at least one processor individually or collectively, further cause the electronic device to:
identify a corresponding area of the content on the rear part based on the position and the size of the content, and
determine an area including the corresponding area as an area of the object.
9. The electronic device of claim 8 , wherein the instructions, when executed by the at least one processor individually or collectively, further cause the electronic device to:
identify the corresponding area of the content on the rear part by further considering a shape of the content, and
determine an area extended from the corresponding area as the area of the object based on a shape of the corresponding area.
10. The electronic device of claim 1 ,
wherein the front part of the transparent display includes a first transparent display panel and a first touch panel covering the first transparent display panel, and
wherein the rear part of the transparent display includes a second transparent display panel and a second touch panel covering the second transparent display panel.
11. A method of controlling an electronic device, the method comprising:
identifying a position and a size of content requiring security on a screen displayed on a front part of a transparent display of the electronic device;
identifying at least one of a color or a brightness of an object corresponding to the content, to be displayed on a rear part of the transparent display; and
displaying, through the transparent display, the object having the identified color and brightness in an area of the rear part, determined based on the position and size of the content.
12. The method of claim 11 , wherein the identifying of the at least one of the color or the brightness of the object comprises identifying at least one of the color or the brightness of the object corresponding to the content based on at least one of a color, a brightness, or presence or absence of a background, of the content.
13. The method of claim 12 , wherein the identifying of the at least one of the color or the brightness of the object comprises, based on the content not including a background, identifying a brightness different from the brightness of the content, with a difference within a set range, as the brightness of the object.
14. The method of claim 12 , wherein the identifying of the at least one of the color or the brightness of the object comprises:
based on the content including a background, determining whether a difference between a brightness of information other than the background and a brightness of the background is equal to or greater than a set value, and
based on the difference between the brightness of the information and the brightness of the background being equal to or greater than the set value, identifying a brightness different from the brightness of the information, with a difference within a set range, as the brightness of the object.
15. The method of claim 12 , wherein the identifying of the at least one of the color or the brightness of the object comprises:
based on the content including a background, determining whether a difference between a brightness of information other than the background and a brightness of the background is equal to or greater than a set value, and
based on the difference between the brightness of the information and the brightness of the background being less than the set value, identifying a brightness different from the brightness of the background, with a difference within a set range, as the brightness of the object.
16. The method of claim 11 , further comprising:
based on at least one of a color or a brightness of the content being changed, changing at least one of the color or the brightness of the object in real time based on the changed at least one of the color or the brightness of the content.
