Embodiment 1

[0030] see figure 1 and figure 2 , are respectively the diagram of the thermo-optic ghost imaging device of the present invention to realize image encryption transmission and the schematic diagram of the embodiment of image encryption based on the principle of thermo-optic ghost imaging: the thermo-optic ghost imaging device used to realize the method of the present invention includes: natural light 1, frosted glass 2 , 50:50 beam splitter 3, the devices used in the signal optical path are triangular hole object 4, converging mirror 5, and single photon detector 6 in turn, and the devices used in the reference light path are imaging lens 7 and CCD detector 8 in turn, using computer matlab software Implement Correlator 9.

[0031] Based on the principle of thermo-optical ghost imaging, the composition of the image encryption device is realized, including: a ghost imaging system (the device marked with a dotted line frame), an encryption scrambling matrix 10, and a key (decryp...

Embodiment 2

[0035] According to the principle of encryption, the encryption scrambling matrix 10 can be placed in the reference light path, and the data sequence M collected by the reference light path 1 m 2 …M N Scramble to N 1 N 2 …N N , can also realize the encrypted transmission of the image. The corresponding decryption transformation matrix (key) is the received data sequence N 1 N 2 …N N Revert to M 1 m 2 …M N To realize the decryption of the image.

Abstract

The invention discloses an image encryption transmission method based on the thermal light ghost imaging principle, and pertains to the field of information safety. The objective of the invention is to solve distortion and compression ratio reduction problems in the image encryption process, through the characteristic that the thermal light ghost imaging dual optical paths satisfy image data obtained through measurement, image encryption transmission is realized by scrambling the signal sequence adopted by one of the optical path, the scrambled pulse sequence is recovered and encrypted with a key (the correct transformation matrix), and then image decryption is realized through appropriate measurement. The method of the invention has the following advantages that the image encryption transmission method based on thermal light ghost imaging is provided, the thermal light ghost imaging principle is introduced into the encryption algorithm, so the encryption algorithm has advantages of high safety and no distortion, and the image compression ratio will not be reduced.

Description

technical field [0001] The invention belongs to the technical field of information security, and relates to an image data encryption transmission method, in particular to an image encryption transmission method based on the thermal light ghost imaging principle. Background technique [0002] With the rapid development of Internet technology, we have entered the information age. How to ensure the speed and security of information transmission is of great significance. Digital images have become one of the main network interaction objects because they contain rich and intuitive information. Image interaction is widely used in important institutions such as military systems, government agencies, financial systems, and healthcare. The security problem of image transmission is worrying, and it is generally paid attention to by people. How to ensure the safe interaction of digital images and prevent images from being intercepted by third parties, maliciously tampered with, illega...
