Abstract

The invention relates to a digital holographic information hiding and extracting method and system. The hiding method comprises the steps of obtaining to-be-hidden information; performing pixel expansion on the to-be-hidden information by using visual cryptography to obtain a plurality of visual keys; utilizing a digital holographic imaging system to make each visual secret key into a digital hologram; and hiding the digital hologram in different host images according to different attenuation proportions to obtain hidden information. According to the digital holographic information hiding andextracting method and system provided by the invention, the safety and robustness in the information transmission process are improved.

Description

technical field [0001] The invention relates to the field of information encryption and hiding, in particular to a method and system for hiding and extracting digital holographic information. Background technique [0002] Since entering the 21st century, with the rapid development of computer technology and communication technology, the Internet and information technology have provided great convenience for people's daily life. Lifestyles such as information interaction, Internet shopping, and electronic payment have entered thousands of households and become an indispensable part of people's lives. In addition, activities such as identity information authentication and financial transactions are gradually realized through information technology. Even in modern warfare, electronic warfare has become a new point of engagement. How to obtain and decipher enemy intelligence and protect the security of one's own intelligence also affects the situation of the battle. [0003] H...
