Problems solved by technology

But traditional information hiding schemes have an obvious common shortcoming: only one carrier is used to embed information
Once the carrier becomes the target of the attacker, the possibility of compromised information is greatly increased

Embodiment Construction

[0050] The embodiments of the present invention will be further described below with reference to the accompanying drawings, but the embodiments described in the present invention are only one possibility, and are illustrative rather than limiting.

[0051] The flow chart of the present invention is as follows figure 1 As shown, first, a mixed fractal matrix is ​​generated, and the fractal matrix is ​​composed of the same and continuous fractal groups; secondly, three different original images are slightly modified according to the mixed fractal matrix and the confidential information to be embedded, and become three Disguised pictures that are very similar to the original images, and send the three disguised images to the three participants for safekeeping; finally, when the confidential information is to be extracted, the first image authentication can be done on the three disguised images. Then do the second authentication for each two camouflaged pictures, and only the two...

Abstract

The invention discloses a method for certifiable (2, 3) confidential image sharing based on a hybrid fractal matrix. First, a mixed fractal matrix is ​​generated, which is composed of the same and continuous fractal groups; second, three different original images are slightly modified according to the mixed fractal matrix and the confidential information to be embedded, and become three images with the original image Very similar camouflage pictures, and send the three camouflage images to the three participants for safekeeping; finally, when you want to extract confidential information, you can first perform the first image authentication on the three camouflage images. The two camouflaged pictures are used for the second authentication, and only the two participants who pass the authentication can extract the confidential information. The invention combines secret sharing and information hiding, realizes efficient information hiding in the pixel domain, and has high security, and the overall storage capacity is also superior to the existing methods.

Description

technical field [0001] The invention belongs to the field of confidential image sharing, and in particular relates to a method and device for certifiable (2,3) confidential image sharing based on a hybrid fractal matrix. Background technique [0002] Nowadays, with the rapid development of the Internet, people can continuously enjoy the fruits of the latest technological revolution. More and more information is transmitted over the Internet. However, network viruses, Trojan horses and illegal organizations that steal information all pose serious threats to information security. Therefore, the security of information transmission becomes particularly important, especially in the political, military and commercial fields. While traditional encryption can keep information secure to a certain extent, this type of technology does not hide the content of the information. On the one hand, secret keys generated to hide information are often unordered symbols, which will be of int...
