Abstract

The present invention relates to a method and system for recovering hidden information of image information based on white light interference, comprising: obtaining a collection of interferograms; the collection of interferograms is a series of interferograms obtained by scanning different positions of a sample with a white light interference imaging system; According to the interferograms in the interferogram set and the spatial moving distance of the piezoelectric actuator in the white light interference imaging system, the spatial position of each interferogram is determined; according to the spatial position of the interferogram, the interferograms in the interferogram set are scrambled to obtain the position Random interferogram set and scrambling mode key; compress each interferogram in the scrambled interferogram set to obtain compressed interferogram set and compressed matrix key; integrate the compressed interferogram set, and integrate the The data is hidden in the host image, and the information hiding image is obtained. The above method of the present invention can reduce coherent noise, improve the quality and speed of information hiding information recovery, and improve system security.

Description

technical field [0001] The invention relates to the technical field of information hiding, in particular to a method and system for recovering image information hiding information based on white light interference. Background technique [0002] With the rapid development of network technology today, the transmission of information is not limited to telephone calls and letters in the traditional sense. Digital information such as pictures, voice, and video are continuously transmitted and exchanged in the network. Now as long as individuals interact with society through the network, their information may be stolen, illegally copied, disseminated and tampered with. The importance of information security is prominently placed before people's eyes. [0003] Information security mainly includes two directions: cryptography and information hiding. [0004] Cryptography is at the heart of information security. It is to turn the information to be transmitted into seemingly chaoti...
