Abstract

The invention provides a multichannel image encryption method and device, a storage medium and an electronic device. The method comprises the steps of encoding a to-be-encrypted multichannel image into a quaternion matrix; generating a chaotic phase mask according to the multi-channel image to be encrypted; performing quaternion transformation on the quaternion matrix in combination with a chaoticphase mask; determining a real value matrix according to the quaternion matrix after quaternion transformation; and determining the ciphertext based on the real value matrix. The chaotic phase mask is generated based on the multi-channel image to be encrypted, and quaternion transformation is carried out, so that the reliability of image encryption can be effectively ensured. The real value matrix covering the real component and the imaginary component of the converted quaternion matrix is determined to determine the ciphertext, so that the reliability of image encryption can be further improved, the multichannel components of the multichannel image can be encoded into a whole, the transmission efficiency can be effectively improved, and the storage is convenient.

Description

technical field [0001] The present application relates to the field of image processing, in particular, to a multi-channel image encryption method, device, storage medium and electronic equipment. Background technique [0002] The development of computer network technology provides a guarantee for information transmission, and due to the openness and sharing of the network, information such as data containing users' personal privacy or corporate business secrets are in danger of being leaked and illegally invaded during transmission, such as The recently reported use of 3D (3Dimensions, 3-dimensional) printing technology to make a plaster face, and successfully cracked the face recognition unlocking function of four popular flagship mobile phones. Nowadays, privacy protection is related to everyone's vital interests. In order to protect information security as much as possible, image encryption has gradually become one of the research hotspots. [0003] Since Refregier (per...
