Embodiment Construction

[0013] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0014] Depend on figure 1 Given, the present invention in concrete implementation, comprises the following steps:

[0015] (1) Spatial data embedding and video reading: read the original video file data, and compress and encode the original video file data, extract the motion vector and change difference, and then use H.264 video steganography based on DCT coefficients The algorithm embeds the spatial data and hides the spatial data, and the video source filter reads the H.264 video file embedded with the spatial data, and sends the data to the network simulation connector (QualNetConnector);

[0016] (2), data separation: use the grammatical analyzer to start by linking the app_fdspvideo.cpp file through the network emulator (QualNet), before transmission, the grammatical analyzer analyzes the video bit stream, and puts the ne...

Abstract

The invention relates to a spatial data double-protocol transmission method based on video steganography, used for effectively ensuring the integrity of spatial data hidden in a video and preventing the spatial data from being lost. The spatial data double-protocol transmission method is as follows: a H.264 video having good network adaptation ability is used as a carrier for hiding the spatial data; the security of the spatial data in a network environment is increased by adopting a H.264 video steganographic algorithm based on DCT (Discrete Cosine Transform) coefficients; a macro block containing the spatial data and a macro block not containing the spatial data are separated by utilizing a grammar analyzer and a multiplexer; transmission is carried out by adopting a TCP (Transmission Control Protocol) and a UDP (User Datagram Protocol) respectively; loss of the spatial data is avoided; the network security transmission efficiency of the spatial data is increased; the double-protocol transmission in the invention is carried out through combination of the TCP and the UDP; the security is high; the capacity is high; the security and the integrity of the spatial data are ensured; loss of the spatial data in transmission is prevented; and thus, the spatial data double-protocol transmission method has high practical value.

Description

technical field [0001] The invention relates to a space data secure transmission technology, in particular to a space data dual-protocol transmission method based on video steganography technology. Background technique [0002] Video steganography is a new type of information security technology developed rapidly with the development of signal processing, applied mathematics, cryptography, communication technology and other related technologies. Combined with spatial data, the spatial data is secretly hidden in ordinary video and other multimedia files for transmission, which can ensure the safe use of spatial data and the safe transmission of spatial data. Compared with spatial data encryption, video steganography technology not only hides the content of spatial data, but also hides the existence of spatial data. Video steganography technology has greater advantages in ensuring the safe transmission of spatial data. [0003] The current video steganography technology main...
