1. A method of providing identification code insertion service for tracking a duplicated image, which is performed by a server, comprising:
(a) receiving an image from a user terminal;
(b) converting the received image to black and white, and selecting a plurality of insertion regions in the converted image;
(c) transforming an image of at least one of a plurality of insertion regions selected at random; and
(d) mapping an identification code and image information included in the transformed image of the insertion region, storing the identification code and the image information in a database, and providing the image in which the identification code is inserted, to the user terminal,
wherein the insertion region refers to a region constituted of at least one pixel among pixels constituting the image, and
wherein the identification code is generated by transforming a binary code of a predetermined size included in a finally selected insertion region.
