Fusion encryption image information hiding method

Abstract

The invention discloses a fusion encryption image information hiding method, and relates to the technical field of image information encryption (communication technology), and the method comprises the steps: S1, preparing original to-be-hidden information; s2, encrypting the hidden information; s3, embedding a hidden file; s4, encrypting an original carrier image; s5, decoding the hidden information; s6, extracting hidden information; the method has the beneficial effects that firstly, by using a multi-layer encryption technology, information with a relatively high confidentiality level is placed in a deep layer, and information with a relatively low confidentiality level is placed in a surface layer, so that authorized personnel of different levels can see encrypted information of corresponding levels, and the security of the encrypted information is improved; compared with the prior art, the method has the advantages that the information transmission safety is improved, meanwhile, the freedom and applicability of watching objects during information encryption are improved, the effective time and the failure time of the information and the key can be set according to the use requirement by adopting the dynamic encryption technology, so that the method is suitable for part of special scenes, and the timeliness of information transmission is improved.

Description

Technical field [0001] The present invention relates to (communication technology) the field of image information encryption technology, specifically a fusion encrypted image information hiding method. Background [0002] With the progress of the times and the development of science and technology, information has become a very important part of our daily life, in daily life all the time to produce information, this information is diverse, there are text information, digital table information and picture information, etc., and information summary will also have important information and unimportant information, etc., and some important information In order to ensure its confidentiality, it is generally necessary to hide and encrypt some information to ensure that it is only for specific authorized groups of people to watch. However, the current hidden encryption methods used are mostly single-layer encryption, and can not be classified according to the confidentiality of the info...

Problems solved by technology

[0002] With the progress of the times and the development of science and technology, information has become an extremely important part of our daily life. Information is generated all the time in our daily life. There are various kinds of information, including text information, digital table information and picture information, etc. etc., and information summary will also have important information and unimportant information, etc., and some important information generally needs to be hidden and encrypted to ensure that it can only be viewed by specific authorized people in order to ensure its confidentiality. , but most of the hidden encryption methods currently used are single-layer encryption, and they cannot be graded according to the confidentiality of the information, which is inconvenient to use. Therefore, we propose a fusion encryption image information hiding method
