An electronic device comprising: a camera including an image sensor; a communication module; a memory; and a processor operationally connected to the camera, the communication module, and the memory, wherein the memory stores instructions that, when executed, cause the processor to: acquire a first image including an external object by using the camera; generate a second image including less information than information included in the first image using an entirety of the first image; transmit the second image to an external electronic device by using the communication module; receive security information corresponding to the second image from the external electronic device by using the communication module; divide, at least partially based on the security information, the first image into a first security level segment and a second security level segment, security level of the second security level segment being higher than security level of the first security level segment; generate a third image in which the second security level segment of the first image is secured at least partially based on the security information; transmit the third image to the external electronic device; and receive from the external electronic device, a fourth image in which the first security level segment of the third image is at least partially corrected by the external electronic device. a camera including an image sensor; a communication module; a memory; and a processor operationally connected to the camera, the communication module, and the memory, wherein the memory stores instructions that, when executed, cause the processor to: acquire a first image including an external object by using the camera; generate a second image including less information than information included in the first image using an entirety of the first image; transmit the second image to an external electronic device by using the communication module; receive security information corresponding to the second image from the external electronic device by using the communication module; divide, at least partially based on the security information, the first image into a first security level segment and a second security level segment, security level of the second security level segment being higher than security level of the first security level segment; generate a third image in which the second security level segment of the first image is secured at least partially based on the security information; transmit the third image to the external electronic device; and receive from the external electronic device, a fourth image in which the first security level segment of the third image is at least partially corrected by the external electronic device. acquire a first image including an external object by using the camera; generate a second image including less information than information included in the first image using an entirety of the first image; transmit the second image to an external electronic device by using the communication module; receive security information corresponding to the second image from the external electronic device by using the communication module; divide, at least partially based on the security information, the first image into a first security level segment and a second security level segment, security level of the second security level segment being higher than security level of the first security level segment; generate a third image in which the second security level segment of the first image is secured at least partially based on the security information; transmit the third image to the external electronic device; and receive from the external electronic device, a fourth image in which the first security level segment of the third image is at least partially corrected by the external electronic device.
