Embodiment Construction

[0045] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0046] Examples of information masquerading methods:

[0047] This embodiment provides an information disguising method, which can enhance the confidentiality and confusion of information, and the disguised data not only maintains the original data format, but also protects the information therein. Taking the masquerading of the key attribute information of vector geographic data as an example, the corresponding flowchart of the information masquerading method is as follows: figure 1 shown, including the following steps:

[0048] (1) According to the information amount of the original information to be disguised, an N-dimensional Kirpinski carpet pattern is generated.

[0049]Among them, the (fractal) dimension N of the Hierpinski car...

Abstract

The invention relates to an information disguising and restoring method, which includes: generating an N-dimensional Kirpinski carpet figure according to the amount of original information to be disguised; filling the N-dimensional Kirpinski carpet with the original information to be disguised In the graphics; in the N-dimensional Kirpinski carpet graphics filled with original information, the Kirbinski carpet graphics of at least two dimensions are rotated and transformed, so as to realize the camouflage of the original information to be camouflaged. The present invention fills the original information to be camouflaged into the N-dimensional Kirpinski carpet pattern, and uses the Kirpinski carpet pattern of at least two dimensions in the N-dimensional Kirpinski carpet pattern to perform rotation transformation, To camouflage the original information, through the use of multi-dimensional camouflage, the degree of information camouflage is improved and the information security after camouflage is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of information security, and in particular relates to a method for disguising and restoring information. Background technique [0002] At present, the protection methods for the key attribute information of vector geographic data mainly include information encryption and digital watermarking. Information encryption is based on the principle of cryptography to encrypt the key attribute data as a whole to generate a data stream that cannot be identified by others and enhance the security of the data. . Although digital watermarking technology has good concealment, it is mainly aimed at the protection of data copyright, and the protection effect on the security of key attribute data itself is not prominent. [0003] Information camouflage technology is a more active information protection technology. By transforming the original vector geographic data, it forms attribute information that is different from the...
