Embodiment Construction

[0006] This specific embodiment adopts the following technical solutions: 1. Carry out feature description to the picture, analyze the scope of the image, and select a part or all of it; 2. Apply an encryption algorithm to encrypt the pixel value of the original image to generate an ID and an encryption key , the generated ID value remains in the image file; 3, the encrypted image and the image feature description synthesize a picture, which has visibility and can protect the privacy in the picture (change the original image screen content); 4, To read the original image, the user needs to authenticate to the central authorization system to obtain the key; 5. Read the image key through the central authorization system, decrypt the encrypted image pixel value, and obtain the original image.

[0007] This specific implementation mode can make the image not only protect privacy and visibility, but also display the decrypted original image under authorized conditions.

Abstract

The invention discloses an image privacy protection processing technology, relating to a technical method capable of encrypting / decrypting a pixel value of a local or entire range in an image. The image privacy protection processing technology comprises the steps of: 1, carrying out feature description on the image and selecting a local or entire range of the image; 2, encrypting the pixel value of the original image by using an encryption algorithm, generating an ID and an encryption key, and maintaining the generated ID in an image file; 3, combining the encrypted image with the image feature description to a picture, wherein the picture has visibility and can protect privacy in the image; 4, reading the original image by carrying out identity authentication to a central authentication system by a user, and obtaining a secret key; and 5, reading the secret key of the image through the central authentication system, decrypting the pixel value of the encrypted image, and obtaining the original image. According to the image privacy protection processing technology, the decrypted original image can be displayed under the conditions of protecting the privacy and being authorized.

Description

Technical field: [0001] The invention relates to an image privacy protection processing technology, in particular to a technical method capable of encrypting / decrypting pixel values ​​in a partial or entire range in an image. Background technique: [0002] The monitoring equipment on urban roads, such as checkpoints, adopts advanced technology to monitor the monitoring section in real time around the clock and record relevant image data. The high-definition checkpoint can clearly display all the detailed information of the vehicle and the facial features of the driver on a single photo. Provide important information and evidence for the timely detection of traffic violation investigations, escapes in traffic accidents, and theft of motor vehicles. Since the image is not blurred and encrypted, the image file will be in a state of leaking privacy. In order to protect privacy and prevent images from being published by interested parties, a technology is needed to protect the p...
