Embodiment Construction

[0032] In order to verify the performance of the algorithm proposed in this paper, two images, A and B, of 8-bit gray-scale satellite images with a size of 512×512 are used in the simulation experiment for transmission and restoration of concealment and falsehood, and B is a newly generated image.

[0033] The real image is satellite image A, such as figure 2 ; carrier image B, such as figure 2 and image 3 .

[0034] A method for transmitting satellite data for concealing reality and displaying false satellites, the specific implementation steps are as follows:

[0035] 1) According to the size of the satellite data to be transmitted: 512×512 8-bit grayscale image A, generate a new image B of the same size according to the predetermined technical approach, or select an image of the same size from the image library as For the new image B to be transmitted, the identification data of image B is obtained at the same time, and the identification data of image B accounts for ...

Abstract

The invention provides a real-hidden and fake-display satellite data transmission method, and aims at solving the problems in data transmission safety and secrecy. After being processed by the method, satellite image data seems like other image data, and satellite secrete data is hidden; and after the transmission data is received, fake data processed by the transmitting end is directly obtained, and the reception end can directly recover the fake data to obtain real satellite image data and secret data. The method is based on information hiding and image processing, real data is hidden and fake data is displayed in the information transmission process, and the method is characterized by disguising information, hiding information, keeping information secret and preventing information from interception.

Description

technical field [0001] The present invention relates to a method of data transmission, in particular to a method of hiding the real resolution and real content of the image data to be transmitted, and transmitting it in the form of other image data, without increasing the amount of data, and what others receive is Fake data, thereby protecting the transmission of real data, belongs to the field of communication (such as data communication technology, etc.). Background technique [0002] The current society is an information society, and the issue of information security has become an increasingly urgent issue. Information hiding, also known as data hiding, is an important branch of information security. It uses human visual redundancy to embed secret information into the carrier, so as to achieve The purpose of secure transmission of confidential information. [0003] There is no special research on transmission technology of concealing truth and revealing falsehood in Chin...
