Description
Technical Field
The present invention relates to the field of block chain data sharing, and more particularly, to a system and method for sharing risk data in a distributed block chain.
Background
With the development of society, the scale of the internet has a leap development, and the generated data is continuously increased, but the data volume of the traditional single organization cannot meet the increasing user pressure all the time, and the development of technology is more and more severe for the richness of data and the data quality. The traditional distributed risk data sharing has the problems of high data leakage probability, difficulty in accounting, low constraint force and the like, so that the traditional risk data sharing is difficult to maintain. The block chain is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism, an intelligent contract, an encryption algorithm and the like, and is currently divided into a public block chain, an industry block chain and a private block chain. The construction of the existing industry risk data sharing platform is realized through an industry block chain, and the shared data of all participating mechanisms is stored in a data storage unit in the mechanism. The platform mainly provides service for participating institutions, and aims to provide pre-affair, middle-affair and post-affair safety guarantee for normal business handling of clients. The participating institutions are both providers of risk data and queriers of risk data. Participating institutions issue query requests in the blockchain by way of "one-to-one" or "one-to-many" broadcasts. If the request information is hit, the corresponding queried mechanism will return the query result.
One of the important features of blockchains is to reduce the cost caused by untrusted relationships or to solve some of the problems caused by untrusted relationships. A federation chain in blockchain technology is well suited for business scenarios where a business consensus can be achieved between federation participants through technical means. In other words, after each enterprise joins the federation, neither the federation organization party nor other federation participants need to be trusted, but only the underlying blockchain technology and industry conventions above the technology need to be trusted. The trust problem between enterprises and alliances is solved through technical means, and a series of extra costs caused by the trust problem in the risk information sharing alliance are reduced.
In summary, at present, there is no reasonable solution to the problem of data sharing, and therefore, how to provide a new solution to solve the above technical problem is a technical problem to be solved in the art.

Therefore, the risk data ciphertext collision library is adopted, and the intelligent contract and distributed accounting function of the block chain is utilized to realize the risk data sharing function; by utilizing the characteristics of the block chain and adopting a mechanism of post accounting and post auditing, the efficiency of data query is not influenced by the distributed framework.
In the above embodiment, the sharing method may further include: and the block chain system adjusts integral values of the service system of the query initiator and the service system of the query feedback party according to the query record according to a preset rule, and stores the change condition of the integral values to a preset position. Furthermore, the integral value of each service system can be monitored, and when the integral value is lower than a preset threshold value, the second query request of the corresponding service system is limited to be received.
For a clearer understanding of the above block chain distributed risk data sharing method, please refer to fig. 8, an overall flow of the risk data sharing method may be as follows:
1) service system a initiates a query request to BS system a. The query interface may support list queries.
2) The BS system A sends a response result to the message queue, acquires the mechanism information of the B according to a mechanism information list synchronized from the block chain, judges the information type supported by the mechanism B, acquires the address of the BS system B in the mechanism B, and forwards the inquiry request to the BS system B after encrypting (the inquiry request is encrypted by an encryption machine and needs to be encrypted in a service system); and, warehousing the query records into Mongodb;
3) and the BS system B acquires the mechanism information in the synchronous block chain, acquires the related information of the mechanism A to judge whether the mechanism A is reliable, and sends a query request to the service system B if the mechanism A is reliable.
4) And the service system B feeds back the query result to the BS system B after receiving the query request.
5) The BS system B feeds back the query result to the BS system A, and the feedback information only contains the hit condition and other necessary information and does not report the original data.
6) And the BS system A receives the query result and sends the query result to the message queue, and the service system A acquires the query result through the message queue.
7) The BS system B sends the relevant information record of the query to a message queue, records the query information and the result to a block chain (a peer node writes a shared account book through an intelligent contract) through the message in the message queue of the consumption, and puts the response result of the query request into a Mongobb; .
8) The BS system B synchronizes the block information to confirm that the transaction has been successfully recorded on the block chain. Otherwise, the transaction is sent to the message queue again to wait for the block chain (uplink failure compensation mechanism).
