Abstract

The invention discloses a chaotic-encryption-based medical image share method which comprises a secret image breakdown step, a chaotic image encryption step, a chaotic image decryption step and a secret image recovery step. According to the invention, a threshold secret share scheme is utilized to divide an image into n shadow images, the chaos principle is utilized to encrypt the n shadow images, the encrypted shadow images have the statistical property of white noise, and the collected r shadow images are utilized to recover the secret image. The chaotic-encryption-based medical image share method facilitates data storage and transmission, ensures confidentiality and integrity of significant images, and has strong anti-attack capacity.

Description

technical field

[0001] The invention relates to a method for sharing medical images based on chaotic encryption. Background technique

[0002] The rapid development of computer network and communication technology has promoted the process of social informatization, and the use of the Internet to exchange information is an important feature of the information society. Medical remote diagnosis has made great progress with the development of the Internet, but it is also accompanied by a series of information security problems, such as leakage and tampering of important medical images during transmission.

[0003] Secret sharing system is an important branch in the field of modern cryptography, and it is also an important research content in the direction of information security. In 1979, Shamir and Blakley proposed the secret sharing scheme for the first time. The secret sharing system divides the shared secret into several parts (called sub-secrets) and distributes them to s...
