Abstract
The invention provides a data transaction safety scheduling method, which is characterized by comprising the following steps: step one, after receiving a data calling request of a data demand module, informing a data watermarking system; step two, the data watermarking module watermarks after fetching data from the data storage module; and step three, informing a data demand module after the watermark is printed, and extracting the data printed with the watermark by the data demand module. The invention relates to a transaction and data scheduling method based on a data watermarking technology, which solves the problem of copyright protection in the data transaction and transmission process.
Description
Technical field
The present invention relates to data trade field, more particularly, to data trade security fields.
Background technology
With the continuous development of big data industry, increasing database data is carried out storing, is distributed by network, again
Using.These data often contain huge economic worth, are valuable data resources.Distribute data with network data
Being continuously increased of the demands such as outsourcing, how to protect copyrights of data, make the rights and interests of copyrights of data owner obtain protection to be increasingly becoming
Major issue urgently to be resolved hurrily；Transaction based on data watermark technology and data dispatching method are to solve data trade and transmission
During copyright problem effective way.
Content of the invention
Present invention aims to the deficiencies in the prior art, a kind of safe data trade dispatching method is proposed.
The technical scheme is that：A kind of data trade sacurity dispatching method, comprises the following steps：
Step one, after receiving the data call request of demand data module, notifies data watermark system；
Step 2, data watermark module watermark after data memory module fetches data；
Step 3, watermark notifies demand data module after accomplishing fluently, and demand data module extracts the data having accomplished fluently watermark.
Preferably, step 2 also includes, and data watermark module, after data memory module fetches data, carries out data watermark pre-
Process, then watermark again；
Preferably, watermarking images are changed by described data watermark pretreatment by the pretreatment that Arnold displacement and position are decomposed
For mixed and disorderly binary sequence, as actual watermark information to be embedded.
For this purpose it is proposed, the present invention also provides a kind of data trade sacurity dispatching system it is characterised in that including：Data dispatch
Module, data memory module, data watermark module：
Described data dispatch module, for sending data call request to data watermark module, for data trade interface
Feedback data watermark status information；
Described data memory module, for data storage；
Described data watermark module, is used for carrying out data watermark generation, data watermark embeds and data watermark extracts.
Preferably, described data memory module is Data Persistence Layer.
Preferably, described data trade sacurity dispatching system, also includes data check module, for by default verification
Algorithm carries out data check to the data in caching, so that the data in caching is consistent with the data in Data Persistence Layer.
Beneficial effect：
Data trade sacurity dispatching method and system of the present invention, in conjunction with data digital watermark and data trade dispatching party
Method, solves the problems, such as copyrights of data ownership mark during data trade, and can asking according to data trade scheduler module
Ask, carry out watermark on demand, further can feed back watermark status information on demand, be easy to data trade and dynamically manage.
For image class data watermark, increased watermark pretreatment step before watermark, compared with prior art strengthen
The security of watermark, improves the detection performance of watermark.
Brief description
In order to be illustrated more clearly that the technical scheme of the embodiment of the present invention, below will be attached to use required in embodiment
Figure be briefly described it should be apparent that, drawings in the following description are some embodiments of the present invention, common for this area
For technical staff, on the premise of not paying creative work, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the flow chart of the data trade sacurity dispatching method of embodiment of the present invention；
Fig. 2 is the schematic diagram of the data trade sacurity dispatching system that the present invention sends out embodiment.
Specific embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention is described in detail.
As shown in figure 1, provide in the embodiment of the present invention the technical scheme is that：A kind of data trade sacurity dispatching
Method, comprises the following steps：
S001, after receiving the data call request of demand data module, notifies data watermark system；
S002, data watermark module watermark after data memory module fetches data；
S003, watermark notifies demand data module after accomplishing fluently, and demand data module extracts the data having accomplished fluently watermark.
Preferably, S002 also includes, and data watermark module, after data memory module fetches data, carries out data watermark and locates in advance
Reason, then watermark again；
Preferably, for image class data, data watermark pretreatment mode is the pretreatment decomposed by Arnold displacement and position
Watermarking images are converted to mixed and disorderly binary sequence, as actual watermark information to be embedded.
Preferably, for image class data, watermark process：Original image is carried out 8X8 piecemeal DTC conversion, selects each
8 DCr intermediate frequency coefficients of sub-block as the embedded location of watermark, and with the PJGE luminance quantization table that combines with visual characteristic Lai
Determine the proportionate relationship of these coefficient embedment strengths.To one suitable region of search of the embedment strength factor, heuristically select
Certain embedment strength value carries out watermark and embeds, and introduces to comment better than the image quality evaluating method of Y-PSNR and mean square deviation
Valency contains the distortion situation of watermarking images.If picture quality is unsatisfactory for the desired close distortion factor, constantly adjust embedded strong
Angle value, thus the position information of watermarking images is embedded in 8 intermediate frequency coefficients of each sub-block with different intensity respectively.
Provide in the embodiment of the present invention as shown in Figure 2 and the technical scheme is that：
A kind of data trade sacurity dispatching system, including：Data dispatch module 201, data memory module 202, data watermark mould
Block 203：
Described data dispatch module 201, for sending data call request to data watermark module 203, for handing over to data
Easily interface 204 feedback data watermark status information；
Described data memory module 202, for data storage；
Described data watermark module 203, is used for carrying out data watermark generation, data watermark embeds and data watermark extracts.
Preferably, described data memory module 202 is Data Persistence Layer.
Preferably, described data trade sacurity dispatching system also includes data check module, for by default verification
Algorithm carries out data check to the data in caching, so that the data in caching is consistent with the data in Data Persistence Layer.
Embodiment of above is merely to illustrate the present invention, and not limitation of the present invention, common about technical field
Technical staff, without departing from the spirit and scope of the present invention, can also make a variety of changes and modification, therefore all
Equivalent technical scheme falls within scope of the invention, and the scope of patent protection of the present invention should be defined by the claims.
