1. An electronic device comprising:
at least one memory storing one or more computer programs;
a camera; and
at least one processor,
wherein the one or more computer programs include computer-executable instructions that, when executed by the at least one processor, cause the electronic device to:
obtain a raw image for an external object from the camera in a secure environment of the at least one processor and store the raw image in the at least one memory,
obtain, in the secure environment, a first image by performing first image processing on the raw image and second image processing on an output of the first image processing of the raw image,
obtain, in a normal environment of the at least one processor, a second image by performing the second image processing on the raw image, and
based on obtaining of a verification request related to the second image:
obtain, in the secure environment, the second image,
obtain, in the secure environment, a third image by performing the first image processing on the second image, and
identify integrity of the second image based on comparing the first image and the third image.
