Problems solved by technology

These have caused the traditional encryption methods for natural images to not be well suited for medical images.
Judging from the existing encryption methods for medical images, most of the methods are carried out in the airspace of the image, that is, the pixels of the image are encrypted. In order to increase the encryption effect, it is generally necessary to encrypt all the pixels, and the amount of encrypted data is large.

Abstract

The invention provides a real-time encryption and decryption algorithm in the medical image wavelet domain based on multiple chaotic systems. The real-time encryption and decryption algorithm in the wavelet domain of medical images based on multiple chaotic systems includes the following steps: decomposing medical images, encrypting wavelet coefficients, obtaining encrypted medical images and decrypting medical images. Compared with related technologies, a real-time encryption and decryption algorithm of medical image wavelet domain based on multiple chaotic systems provided by the present invention proposes to use LeGall5 / 3 integer wavelet transform to perform three-level wavelet classification on the original medical image, which fully reduces the distance between medical image pixels. Correlation, which has high time efficiency and high security when the initial value of chaos and system parameters are unknown.

Description

Technical field [0001] The present invention relates to the field of chaotic cryptography in cryptography, and more particularly to a medical image wavelet domain real-time plus interpretation algorithm based on a multi-chaotic system. Background technique [0002] Medical Informationization and Remote Medical, the rapid development of online medical treatment promotes online transmission of medical information, medical images as an important part of medical information into the main content of transmission. However, medical images containing important medical diagnostic information are transmitted on public networks. Many safety hazards such as privacy leaks. How to effectively protect medical image security into research hotspots, data encryption This active content protection method still has a wide range of application prospects. [0003] Medical images have a very different feature of natural images. First, with large data volume, medical images often have high resolution du...
