According to the data of honouring an agreement, the contractual capacity of first user is assessed, and generates assessment data, it is described Assess data in comprising whether honour an agreement on time, the one or more in degree of honouring an agreement；

The assessment data are sent to the server.

The contract that Fig. 4 is the first user that the embodiment of the present application provides signs request schematic diagram.

Figure 4, it is seen that client corresponding to first user's startup optimization contract signing platform, logs in the client Afterwards, signed in contract and show contract signing requests for page corresponding to platform in client, shown in the page contract type, by About square, carrying out of a contract time and the obligation executed one's promises etc..When the first user inputs the contract content of correlation in the page Afterwards, control is submitted in triggering, is considered as to server and is sent contract signing request.

Fig. 5 is the carrying out of a contract schematic diagram for the first user that the embodiment of the present application provides.

From figure 5 it can be seen that server, after the contractual relation between the first user and second user is established, first uses The carrying out of a contract page is shown in client used in family, comprising contractual relation, by about square, contract in the carrying out of a contract page Time and carrying out of a contract data are fulfiled, is included in the carrying out of a contract data and fulfils data, Ke Yitong caused by different time points Cross a page to show, can also be shown by multiple pages, be not specifically limited here.

Fig. 6 is that the contractual capacity for the second user that the embodiment of the present application provides assesses schematic diagram.

From fig. 6 it can be seen that second user is made after the contract for receiving the first user signs request in second user Display, which is honoured an agreement, in client assesses the page, promoter's (user's mark of the first user in the page comprising contractual relation Know), the first user send honour an agreement data and second user assessment data.When second user inputs assessment in the page After data, control is submitted in triggering, is considered as to send to server and is assessed data, is commented with the contractual capacity to the first user Estimate.

Generate the substantial amounts of data for being used to assess user credit in the above-described embodiments, in order to ensure these data not by Distort, Fig. 7 is a kind of schematic flow sheet for data processing method based on block chain that the embodiment of the present application provides.Methods described Can be with as follows.The executive agent of the embodiment of the present application is block chain node in block chain network.

Step 701：Block chain node determines the contractual relation established between the first user and second user.

In the embodiment of the present application, there is provided contract signs platform, and the contract is signed platform and can be used as in block chain network A block chain node.The block chain node can determine whether establish contractual relation between the first user and second user.

Specifically, first, receive the contract that the first user sends and sign request, the contract, which is signed, includes second in request The user's mark and contract data of user, the contract data exist for characterizing first user and being promised to undertake to the second user The obligation fulfiled in setting time.

Secondly, the contract is signed into request and is sent to second user corresponding to user's mark of the second user.

Finally, the confirmation that the second user returns is received, and according to the confirmation, establishes described first and uses Contractual relation between family and the second user.

Concrete implementation mode may refer to the content shown in Fig. 1, no longer repeat one by one here.

Further, since contractual relation belong to conclude both sides or it is multi-party between a kind of social relationships, this contractual relation Whether disclose and be also required to both sides or Multi Part Negotiation determination.In the embodiment of the present application, established in the first user and second user During contractual relation, the data of the first user or the second user caused user behavior data during carrying out of a contract can be consulted Access rights.Here data access authority can be understood as disclosing scope, i.e. which user is able to access that the first user or the Two users caused user behavior data during carrying out of a contract.Data access authority can basis in the embodiment of the present application Data type is determined, and can also be determined according to data source, is not specifically limited here.

Assuming that using data source as according to the data access authority for determining different user behavioral data, then in the first user When establishing contractual relation with second user, the data access rights comprising data source and user behavior data in the contractual relation Mapping relations between limit, such contract contract platform when getting user behavior data caused by different user, Ke Yigen According to the mapping relations, the data access authority of user behavior data is determined.

The contractual relation is stored into block chain.

It should be noted that when establishing contractual relation between the first user and second user, for the contractual relation Contract content can be stored in block chain according to existing block chain technology；The first user and second can also be utilized as to use The contract content is encrypted the private key of first public and private key centering of family configuration, the contract content quilt obtained after encryption It is stored in block chain, so, the contract content can only be concluded both sides' (i.e. the first user and second user) by the by contract The public key of one public and private key centering can browse.

Step 702：Block chain node is based on the contractual relation, obtains the user behavior associated with the contractual relation Data, and determine the data access authority of the user behavior data.

In the embodiment of the present application, once establishing certain contractual relation between the first user and second user, then First user or second user will produce user behavior data when fulfiling voluntary corresponding to the contractual relation, then block chain link Point can obtain the user behavior data associated with the contractual relation.

Due to storing the mapping between data source and the data access authority of user behavior data in contractual relation Relation, then based on described mapping relations, it may be determined that the data source of the user behavior data got, and be based on The data source, determines the data access authority of the user behavior data, and the data access authority is included and ordered by contract Vertical both sides access, accessed by the user that specified relationship is established with contract conclusion both sides, one kind in unrestricted access, described to specify Relation includes the one or more in kinship, friends, classmate's relation.

In the embodiment of the present application, the user behavior data associated with the contractual relation includes but is not limited to：Honour an agreement Data, assess data.

Specifically, the data of being honoured an agreement caused by during the contractual relation is fulfiled that first user sends are received, The contractual relation is included in the data of honouring an agreement, fulfils behavioral data voluntary corresponding to the contractual relation and the row For the generation time of data.

Here receive the first user and send the specific implementations of data of honouring an agreement and may refer to tool in embodiment illustrated in fig. 1 Hold in vivo, no longer repeat one by one here.

Get the first user transmission honour an agreement data when, if in the contractual relation comprising first user produce User behavior data corresponding to access rights be by contract conclude both sides access, then it is determined that the data of honouring an agreement data visit It is to conclude both sides by contract to access to ask authority.

If served as reasons in the contractual relation comprising access rights corresponding to user behavior data caused by first user With contract conclude both sides establish specified relationship user access, then it is determined that the data access authority of the data of honouring an agreement be by with Contract concludes user's access that both sides establish specified relationship.

The data of honouring an agreement are sent to the second user.

Specifically, the assessment number assessed the contractual capacity of first user that the second user is sent is received According to, it is described assessment data in comprising whether honour an agreement on time, the one or more in degree of honouring an agreement.

Here the specific implementation of reception second user transmission assessment data may refer to the tool in embodiment illustrated in fig. 1 Hold in vivo, no longer repeat one by one here.

When getting the assessment data of second user transmission, if being produced in the contractual relation comprising the second user User behavior data corresponding to access rights be by contract conclude both sides access, then determine it is described assessment data data visit It is to conclude both sides by contract to access to ask authority.

If served as reasons in the contractual relation comprising access rights corresponding to user behavior data caused by the second user With contract conclude both sides establish specified relationship user access, then determine it is described assessment data data access authority be by with Contract concludes user's access that both sides establish specified relationship.

Step 703：Block chain node determines the use according to the preset relation between data access authority and processing strategy The processing strategy of family behavioral data, the processing rule to match with the data access authority is included during the processing is tactful.

In the embodiment of the present application, block chain node can pre-establish reflecting between data access authority and processing strategy Relation is penetrated, so, once the data access authority of user behavior data is different, then and corresponding processing strategy is also different.

In the embodiment of the present application, can be, but not limited to data access authority being divided into following several：

1st, both sides are concluded by contract to access.Accessed that is, user behavior data only allows contract to conclude both sides, i.e., originally Apply for that the first user in embodiment and second user access.

2nd, accessed by the user that specified relationship is established with contract conclusion both sides.That is, user behavior data is not only permitted Perhaps contract is concluded both sides and accessed, i.e., the first user and second user in the embodiment of the present application access；Also allow and the first user The other users that specified relationship is established with second user access, such as：User's mark of first user and the user of second user Mark belongs to a customer group, then the other users in the customer group can be defined as and the first user and second user foundation The other users of specified relationship.
