Embodiment Construction

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

[0046] Embodiment of information camouflage method:

[0047] This embodiment provides an information masquerading method, which can enhance the confidentiality and confusion of information. The masqueraded data not only maintains the original data format, but also protects the information therein. Taking the camouflage of key attribute information of vector geographic data as an example, the flow chart corresponding to the information camouflage method is as follows figure 1 As shown, it specifically includes the following steps:

[0048] (1) According to the information amount of the original information to be camouflaged, an N-dimensional Hirpinski carpet graph is generated.

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

Abstract

The invention relates to an information disguising and restoring method which comprises the following steps: generating an N-dimensional Hilberpinski carpet graph according to the information amount of original information to be disguised; filling original information to be camouflaged into the N-dimensional Hilberpinski carpet graph; and in the N-dimensional Hilpinski carpet graph filled with theoriginal information, performing rotation transformation on the Hilpinski carpet graphs of at least two dimensions, thereby realizing camouflage of the original information to be camouflaged. According to the invention, to-be-camouflaged original information is filled into an N-dimensional Hilberpinski carpet graph; the N-dimensional Hilpinski carpet graph is adopted, the Hilpinski carpet graphsof at least two dimensions in the N-dimensional Hilpinski carpet graph are adopted for rotation transformation to camouflage the original information, and therefore the information camouflage degree is improved and the information security after camouflage is guaranteed by adopting multi-dimensional camouflage.

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 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 recognized by others and enhance data security. However, the encrypted data stream is more likely to attract the attention of attackers and make the data subject to centralized attacks. . Although the digital watermarking technology has good concealment, it is mainly for the protection of data copyright, and its protection effect on the security of the key attribute data itself is not outstanding. [0003] Information camouflage technology is a more active information prote...
