, allied member's other information may include allied member's title, authentication information (such as password or biological characteristic etc.) and connection
It is mode information etc..
Here, carrying out signature verification to alliance's information about firms can be using being widely used at present and studies and following develop
Various digital signature authentication methods, details are not described herein.
May include at least one of following to operation data information in some optional implementations of the present embodiment:
Data and the preceding data of operation after data manipulation condition, operation.In this way, above-mentioned management server generates number according to data operation request
It according to operation information, can carry out as follows: in response to determining being wrapped in received data operation request to operation data information
Data do not include default blacklist data after the operation included, generate data operation information according to data operation request.
Here, for data addition instruction, data are the data in the database of being added to after operation.For number
For more new command, data are the data that are updated to data before the operation in database after operation.And here, really
Data do not include default blacklist data after fixed operation, i.e., to being added to database or update the data into database
Content recognition is carried out, if being added to the data of database or update into database does not include default blacklist number
According to the data operation request received is just sent to database server., whereas if being added to database or more
Newly the data into database include default blacklist data, then the data operation request received will not be sent to database
Server.As an example, whether can include preset blacklist in text by determining when data include text after operation
To determine, whether data include default blacklist data to keyword after operation, for example, preset blacklist keyword may include
Pornographic associative key, drugs associative key, violence associative key, advertising keyword etc..Another example, when
When data include picture after operation, content recognition can be carried out to picture, obtain content keyword, then passed through obtained by determining
Content keyword whether belong to above-mentioned preset blacklist keyword whether data include default blacklist after operation to determine
Data.
It is understood that above two optional implementation can be individually performed.Above two optional implementation
Execution can be combined.I.e., it is possible to be formerly in data operation request allied member's information carry out signature verification pass through and
Data do not include default blacklist after determining the operation included by the operation data information in received data operation request
In the case where data, data operation information is generated according to data operation request.
In some optional implementations of the present embodiment, data may include at least one of following after aforesaid operations:
Text, picture, label information and user behavior information.In this way, above-mentioned timing 200 can also include the following steps 201 ':
Step 201 ', management server in response to determine in received data operation request in operation data information
Including data after operation, generate the content score value of data after object run, and by content score value generated with received
The Data Identification correspondence of the targeted data of data operation request is stored in database server.
Here, data are in received data operation request to included in operation data information after object run
Data after operation.
Here, label information is to the keyword that data entire content is described after operation.For example, after operation in data
Text and picture be respectively text and picture in Webpage, then the label after operating in data can be the Webpage
Subject key words.
Here, user behavior information may include user to the click of text included by data after operation and picture, clear
The behavioural informations such as look at, forward, thumbing up.
Here it is possible to generate the content score value of data after object run, wherein content score value using various implementations
It is the numerical value quantified to the value of data after object run.
As an example, here it is possible to data are at least one attribute under every attribute after object run determining first
Then score value is again weighted identified at least one attribute score value according to default weight coefficient, to obtain target behaviour
The content score value of data after work.For example, can use natural language processing technique pair for the text in data after object run
Content of text carries out semantic analysis, to obtain the emotion attribute score value of content of text.It for another example, can be by number after object run
The product of the hits and the first predetermined coefficient in user behavior information in is as click number attribute score value.It also for example, can
Using the product of browsing number and the second predetermined coefficient in the user behavior information after by object run in data as browsing number category
Property score value.It also for example, can be by the forwarding number and third predetermined coefficient in the user behavior information in data after object run
Product is as forwarding number attribute score value.Also for example, number can will be thumbed up in the user behavior information in data after object run
It is used as with the product of the 4th predetermined coefficient and thumbs up number attribute score value.
By step 201 ', for the data stored in database server, correspondence is stored with content score value.In this way,
When allied member's terminal initiates data inquiry request to management server, the sequence from high to low according to content score value can choose
Show query result, so as to provide content score value higher data for user, i.e., the more data of " high-quality ".
Step 202, the data operation request that database server is sent in response to receiving management server, parses and holds
The received data operation request of row.
In the present embodiment, database server can be in the feelings for the data operation request for receiving management server transmission
Under condition, parses and execute received data operation request.For example, the data manipulation worked as in received data operation request refers to
Enable when being data addition instruction, database server can by institute's data to be added in operation data information be added to
Position indicated by concrete database location information in operation data information.Data in the data operation request received
Operational order be data more new command when, database server can by database to the more specific location information in operation information
The data of indicated position are updated to the updated data in operation data information.When the data operation request received
In data manipulation instruction be data delete instruction when, database server can will in operation data information database tool
The data of position indicated by the information of body position are deleted.When the data manipulation instruction in the data operation request received is data
When inquiry instruction, database server can be according to the query condition information in operation data information, inquiring data and by institute
The data found are sent to management server.
It is understood that since the database application of different software type is suitble to the data type of storage different, it is real
In trampling, difference can be stored using the database application of different software type in database server (or server cluster)
The data of type.For example, can in HBase, (HBase be a distributed open source number towards column by text data store
According to library) in database, and other data and various statistical data are stored in MySQL (MySQL is a relevant database
Management system is developed by MySQL AB company of Sweden, belongs to product under Oracle at present.) in database.
Step 203, the data operation information that block chain node device is sent in response to receiving management server, will be received
To data operation information be added in the data operation information buffer pool being locally stored.
In the present embodiment, block chain node device can receive the data operation information of management server transmission
In the case of, the data operation information received is added in the data operation information buffer pool being locally stored.
Here, block chain node device can store data operation information buffer pool, and it is slow to be stored in data operation information
The data operation information rushed in pond is that there are no processed data operation informations, if data operation information is selected and generates
Block, then selected data operation information can be deleted from data operation information buffer pool.
Step 204, block chain node device is in response to determining that obtaining data operation information records permission, what is be locally stored
Data operation information is chosen in data operation information buffer pool and generates new block, and block generated is concatenated into local block
Chain, and block generated is broadcast to other block chain node devices.
Here, block chain node device can record permission using preset common recognition algorithm competition data operation information, and
In the case where determining that obtaining data operation information records permission, take various implementations in the data manipulation letter being locally stored
Data operation information is chosen in breath buffer pool and generates new block, block generated is concatenated into local block chain, and will
Block generated is broadcast to other block chain node devices.
For example, can more first be competed according to the longer block chain node device of line duration to record permission.It can also be by
It is more first competed according to the higher block chain node device of prestige coefficient to record permission.
After having chosen data operation information, selected data operation information can be generated how block gives birth to here
It is the prior art studied and applied extensively at present at block, details are not described herein.For example, can be first with Merkel tree
As block volume data, then (Merkle Tree) technology generates the Merkel tree of selected each data operation information
Random number, the selected each data operation information and Merck generated generated again with the cryptographic Hash of a block, at random
You generate block head data by the tree root of tree, and last combination region build data and block volume data obtain block.Certainly, optional
Ground can also include the timestamp value for generating the time of block in above-mentioned block head.
It is understood that when block chain node device receives the block that other block chain node device is sent, it can
The block received is concatenated into local block chain, so that different block chain node devices can save identical data behaviour
Make information block content.
The system provided by the above embodiment of the application is by management server according to from the received number of allied member's terminal
According to operation requests, data operation information is generated, and data operation information generated is sent to block chain node device to deposit
It stores up in block chain, then data operation request is sent to database server to parse and execute data operation request.To,
