Abstract

The invention provides an image processing method and device. The method comprises the following steps: dividing an image based on a preset resolution, performing hash transformation on a preset number of most significant bits of three color components of image blocks obtained by segmentation, and obtaining a hash result of each image block; correspondingly determining an image index of the image based on the hash result of each image block; constructing identification information of each image block based on the block position of each image block, the image index of the image, a shooting position of the image and the shooting time of the image; and embedding the identification information of each image block in the preset number of most significant bits of three color components of each image block, and verifying the image based on the identification information extracted from the preset number of most significant bits of three color components of each image block. By implementation of the image processing method and device provided by the invention, the authenticity and integrity of the captured image can be effectively verified.
