1. An image processing method for de-identifying and restoring image information, which is performed by an image processing system, comprising:
detecting at least one object information area in image information;
de-identifying the detected object information area by using an encryption key generated in relation to the detected object information area; and
restoring the de identified object information area by using the encryption key,
wherein the de-identifying comprises de-identifying the detected object information area such that the de-identified object information area is classified differently in accordance with a type of an object included in the object information area, and
wherein restoring the de-identified object information area comprises classifying an object included in the restored object information area depending on a type of the restored object information area.
