Method and system of detecting image tampering, electronic device and storage medium

A system of detecting image tampering, comprising:

• an extraction module configured for carrying out block segmentation on a to-be-detected image to segment the to-be-detected image into a plurality of image small fragments, and extracting initial tampering detection features from all the image small fragments;
• a detection module configured for encoding the extracted initial tampering detection features with a predetermined encoder to generate complicated tampering features, and determining a tampering detection result corresponding to the to-be-detected image according to the generated complicated tampering features, wherein the tampering detection result comprises an image-tampered result and an image-not-tampered result.

An electronic device, comprising a processing equipment and a storage equipment, wherein the storage equipment stores an image tampering detection system comprising at least one computer readable instruction;

• and the at least one computer readable instruction is executed by the processing equipment to implement the following operations:
• step A, carrying out block segmentation on a to-be-detected image to segment the to-be-detected image into a plurality of image small fragments, and extracting initial tampering detection features from all the image small fragments;
• step B, encoding the extracted initial tampering detection features with a predetermined encoder to generate complicated tampering features, and determining a tampering detection result corresponding to the to-be-detected image according to the generated complicated tampering features, wherein the tampering detection result comprises an image-tampered result and an image-not-tampered result.
