Electronic device and method for securing personal information included in image

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.
