Description
Technical field
The present invention relates to a kind of system, and in particular to encryption, the retrospective big number of block chain of anti-tamper, transaction record
According to analysis of market conditions system.
Background technology
The opportunity that business intelligence is had the initiative in hands in market competition for enterprise, catches the instant to die is understood in time,
And then it is most important to obtain triumph.Have existed since ancient times for the application of information science and intelligence analysis militarily, also commercially has extensively
Using.
With the broad development of internet, the increase of data magnanimity, information also more transparence, networking, propagate it is rapid and
It is in extensive range.But also bring some problems simultaneously, such as information island, information fragmentation, irrelevant information are excessive, falseness, mistake,
Contradictory information is more, and it is difficult to obtain true, accurate, detailed business intelligence within the very first time to cause user.
Block chain big data analysis of market conditions platform provides first-hand, professional, detailed, accurately individual in the very first time for user
The business intelligence of property, available for precision marketing, investment risk control, the prediction of industrial economy developing state, Stock Market Forecasting, enterprise
The fields such as reference is assessed, science and technology item is declared, market business opportunity is found, the automatic monitoring of public sentiment.During the service object of the platform includes
Small enterprise, scientific research institutions, venture capital enterprises, finance service, security analysis mechanism, individual investor etc..
The content of the invention
The technical problems to be solved by the invention are being acquired to business intelligence, analyze, handle during, prevent
Leaking data, protection is personal and enterprise's privacy, it is therefore intended that providing can tracing function with encryption, anti-tamper, transaction record
Analysis of market conditions system, the problem of solving above-mentioned.
The present invention is achieved through the following technical solutions：
Block chain big data analysis of market conditions system, including market conditions data platform, network crawler system, block chain storage system
System, cloud computing center, user's display end, the market conditions data platform carry out information exchange with network crawler system, and block chain is deposited
Storage system is stored interactive information, and cloud computing center is handled after block chain storage system called data, user
By being operated to user's display end, by the data transfer after the processing in cloud computing center to user's display end；
The market conditions data platform is used for, and will collect target URL library, target URL library is classified；By to target
Data are more accurate when the classification of URL library can allow the web crawlers to retrieve.The network crawler system is used for, and passes through network
Reptile and customization web crawlers, the target URL library data acquisition to all market conditions data platforms；The block chain storage system
Uniting is used for, and storage is encrypted in the information retrieved using block chain non-stop layer storage mode to network crawler system；The cloud
Calculating center is used for, and the information of retrieval is carried out into taxonomic revision by data prediction and data mining and rote learning mode
Store again；User's display end is used for, and the information after cloud computing center processing is transferred, by the market conditions information after processing
Shown in real time in user's display end.
The market conditions data platform includes international and domestic government department's purchase bidding merchant site URL library, international and domestic enterprise
In public institution's purchase bidding merchant site URL library, international and domestic electronic purchasing bid merchant site URL library, the whole nation
Centre, province, city, each science and technology item responsible institution science and technology item in area declare website storehouse, national center, province, city, each economic trade in area
Easy responsible institution's project application website storehouse, whole nation center, save each Committee of Development and Reform's project application website storehouse, it is international and domestic new
The network address such as news, social activity, door, economy, finance and economics, security website, precise classification is carried out by keyword classification mode by each network address.
The network crawler system is made up of N number of web crawlers cloud node, in real time to the target network address of market conditions data platform
Retrieved in storehouse.Retrieval mode includes character search and picture retrieval.
The block chain storage system is made up of N number of block chain collection storage cloud node, can be to N number of web crawlers cloud section
The data of point collection are stored.The cloud computing center includes data digging system, machine learning system, block chain storage system
System；The data digging system is used for, and the information to block chain storage system memory storage is pre-processed, and after being handled
Market conditions information；
The machine learning system is used for, and according to user's display end feedack, pretreated market conditions information is entered
Row screening, the market conditions information after screening is sent to block chain storage system；The block chain storage system is used for, by engineering
The market conditions information blockette for practising screening is stored, and when user's display end is transferred, sends the market conditions information of correspondence subregion.
The block chain that block chain storage system is used be it is a kind of can not distort, full history, the decentralization endorsed by force
Database cloud storage technology.Block chain by all nodes in network participate in jointly calculate, verify mutually the true and false of its information with
Reach the whole network common recognition.Data are uniformly stored on the block chain of decentralization, and data are carried out in the case of initial data is not accessed
Analysis, can both protect to the privacy of data, can safely share again.The data desensitization technology of block chain can guarantee that
Data privacy, opens for the data under secret protection and provides solution.Block chain data desensitization technology is mainly use
The AESs such as Hash processing.Block chain technology can be prevented by multi-signature private key, encryption technology, multi-party computing technique
Data-privacy is revealed.It is placed on after data are hashed processing on block chain, uses digital signature technology, it becomes possible to allow those to obtain
The people that must be authorized can just conduct interviews to data.Block chain can be registered to data assets, and transaction record can be reviewed.
Pretreatment in the data digging system be by the data storage category in block chain storage system, industry,
Keyword, the amount of money, time, region are carried out after taxonomic revision, are sent to machine learning system.
User's display end is mobile phone, tablet personal computer, vehicle-mounted computer, PC ends.User's display end is fixed by user
The market conditions information read transfers corresponding market conditions information out of block chain storage system, and market conditions data are shown.
Block chain big data analysis of market conditions system can abolish the threat for illegally copying data, ensure the conjunction of data owner
Method rights and interests.On the other hand, block chain, which is provided, can review path, can effectively crack data and really weigh problem.Block chain passes through network
In multiple nodes for participating in calculating participate in calculating and the record of data jointly, and verify the effective of its information mutually, both may be used
To carry out information anti-fake, path can be reviewed by providing again.The Transaction Information of each block is stringed together, complete friendship is formed
Easy itemized bill, it is very clear, transparent per transaction the ins and outs.
The present invention compared with prior art, has the following advantages and advantages：
