The present invention provides a kind of technical solution referring to FIG. 1-2: a kind of considerable information hide system based on Fractal Tree
System, including transmitting terminal 100 and receiving end 200, transmitting terminal 100 include picture decomposition unit 110, with 110 phase of picture decomposition unit
Picture file with transmission is decomposed into multiple sons by the coding unit 120 and transmission unit 140 of connection, picture decomposition unit 110
Image, coding unit 120 are used to carry out subgraph and key file number editor, transmission unit 140 for image data with
And the transmission of key file, receiving end 200 includes image generation unit 210, image generation unit 210 and transmission unit 140
It is connected, for the reception of data and the synthesis of picture.
In the present embodiment, the picture breakdown for needing to transmit is multiple subgraphs by picture decomposition unit 110, also,
During its decomposition, the decomposition route of its image and decomposition region are retained, meanwhile, pass through coding unit 120
Decomposition region and subgraph are encoded, and coding between the two corresponds to each other, convenient for the splicing of subsequent subgraph and
The formation of image, and route and decomposition region formation key file are decomposed, and be sent to inside image generation unit 210.
In the present embodiment, during use, firstly, transmitting terminal 100 is sent needing to hide the picture sent
To inside picture decomposition unit 110, meanwhile, by picture decomposition unit 110 by picture breakdown to be transmitted be multiple subgraphs,
During its decomposition, it will be formed and decompose decomposition region corresponding to route and subgraph, when picture decomposition unit 110
After being carried out to picture, since picture decomposition unit 110 is connected with coding unit 120, under the action of coding unit 120,
Subgraph and decomposition region can be encoded, since multiple subgraphs are corresponding with multiple decomposition regions respectively, in turn,
In the editing process for carrying out the two, corresponding subgraph can be made identical as the number of decomposition region, be convenient for subsequent son
The splicing of image, after subgraph and decomposition region encode completion, due to control unit 130 and 120 phase of coding unit
Connection, under the action of control unit 130, can carry out multiple subgraphs upsetting processing, further improve the hidden of image
Hiding property, then, sends multiple subgraphs to inside image generation unit 210 again by transmission unit 140, and by resolver
Domain and decomposition route are formed by key file and are sent to inside image generation unit 210, and image generation unit 210 can basis
Coding on decomposition region finds subgraph corresponding with the coding from multiple subgraphs, and the subgraph is spliced to
On decomposition region, and then complete image is formed, also, in the decomposable process for carrying out image, it can also be by carrying out multiple figures
The hiding transmission of sheet data, and then increase the transmission capacity of hiding data.
Further, as picture decomposition unit 110 will with transmission picture breakdown be three parts, respectively subgraph,
Decomposition region and decomposition route.
It is effect picture of the invention such as Fig. 2, in the present embodiment, the image that picture decomposition unit 110 transmits needs
Multiple subgraphs are decomposed into, also, during its decomposition, the decomposition route of its image and decomposition region are protected
It stays, meanwhile, decomposition region and subgraph are encoded by coding unit 120, and coding between the two corresponds to each other, just
In the splicing of subsequent subgraph and the formation of image, and route and decomposition region formation key file are decomposed, and be sent to
Inside image generation unit 210.
Further, decomposing route can be straight line or curve, and subgraph is in irregular.
In the present embodiment, the setting to route is decomposed, depending on picture decomposition unit 110 to the place of image to be transmitted
Picture breakdown to be transmitted is a variety of different shapes, increases the hiding of image in the transmission by reason.
Further, key file is made of decomposition region and decomposition route, and decomposition region is corresponding with subgraph.
In the present embodiment, during use, image generation unit 210 can be according to the volume on decomposition region
Code finds subgraph corresponding with the coding from multiple subgraphs, and the subgraph is spliced on decomposition region, in turn
Complete image is formed, also, in the decomposable process for carrying out image, can also pass through the hiding hair of progress plurality of pictures data
It send, and then increases the transmission capacity of hiding data.
Further, coding unit 120 carries out number editor, and volume between the two to decomposition region and subgraph respectively
Code corresponds to each other.
In the present embodiment, under the action of coding unit 120, subgraph and decomposition region can be compiled
Code in turn, in the editing process for carrying out the two, can make since multiple subgraphs are corresponding with multiple decomposition regions respectively
Corresponding subgraph is identical as the number of decomposition region, convenient for the splicing of subsequent subgraph.
Further, transmitting terminal 100 further includes control unit 130, and control unit 130 is connected with picture decomposition unit 110
It connects, upsets for the sequence to multiple subgraphs.
In the present embodiment, after encoding completion in subgraph and decomposition region, due to control unit 130 with
Coding unit 120 is connected, and under the action of control unit 130, can carry out upsetting processing to multiple subgraphs, further mention
The high hiding of image.
Further, image generation unit 210 includes corresponding unit 211, and corresponding unit 211 is used for subgraph and decomposition
The correspondence in region, synthesis unit 212 is for the synthesis to image；Corresponding unit 211 is adapted with coding unit 120.
In the present embodiment, when image generation unit 210 receive subgraph file transmitted by transmission unit 140 and
When key file, corresponding unit 211 can match the coding of decomposition region and the number from image in key file at this time, make every
A subgraph can be matched to suitable decomposition region.
Further, image generation unit 210 further includes synthesis unit 212, synthesis unit 212 for image synthesis with
And the splicing of subgraph；Synthesis unit 212 is connected with receiving end 200, sends for the image after synthesizing.
In the present embodiment, it after subgraph and decomposition region are mutually matched, can be incited somebody to action by synthesis unit 212
Multiple subgraphs are synthesized, and the picture of completion is formed, and are sent to inside receiving end 200.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
