Problems solved by technology

In the market part, a large number of franchised stores and government and enterprise customers are also widely distributed in various parts of the city. At present, the on-site conditions such as inspections and visits are recorded and reviewed by taking pictures. However, it is difficult to guarantee the authenticity and integrity of the captured images. There is a possibility of counterfeiting, and it is difficult for existing technologies to effectively verify the authenticity and integrity of the captured images

Embodiment Construction

[0053] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0054] First, we will explain the problems that exist when using the existing shooting technology to shoot equipment, and verify the images taken during inspections, visits, and other on-site situation records and audits.

[0055] Technology 1:

[0056] Use the exchangeable image file (EXIF, Exchangeable Image File) that comes with the image to store information such as location (latitude and longitude) of the captured image. EXIF information is specially set for digital camera images, and can record attribute information and shooting data of digital images, mainly including shooting information such as shutter speed, aperture value, etc., and can also include global positioning info...

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.

Description

technical field [0001] The present invention relates to image processing technology in the field of communication, in particular to an image processing method and equipment. Background technique [0002] In the network part, the mobile company has a large number of base stations, warehouses, optical cables, optical communication and optical distribution nodes scattered in every corner of the city, and a large number of maintenance personnel need to carry out daily inspection and maintenance of these devices. In the market part, a large number of franchised stores and government and enterprise customers are also widely distributed in various parts of the city. At present, the on-site conditions such as inspections and visits are recorded and reviewed by taking pictures. However, it is difficult to guarantee the authenticity and integrity of the captured images. There is a possibility of counterfeiting, and it is difficult to effectively verify the authenticity and integrity o...
