Embodiment Construction

[0063] The present invention will be described in further detail below in conjunction with the accompanying drawings, but it is not intended to limit the present invention.

[0064] refer to figure 1 , figure 2 As shown, the embodiment of the present invention discloses a block chain blacklist sharing method using hash desensitization processing. The method is implemented based on the built business platform and block chain platform. The method includes the following:

[0065] Step S1: Each operating institution builds its own business platform and network nodes, and connects the network nodes of each institution to the blockchain network.

[0066] Step S2: Each institution sends a service request to its respective network node through the service platform, wherein the service request includes the upload request, deletion request and query request of blacklist data, and desensitizes and encrypts at least part of the data fields of the upload request Processing; ensure the s...

Abstract

The invention discloses a block chain blacklist sharing method adopting hash desensitization processing, and the method comprises: enabling each operation mechanism to build a business platform and anetwork node of the operation mechanism, and enabling the network node to which each mechanism belongs to be connected to a block chain network; sending service requests to respective network nodes through a service platform, the service requests including an uploading request, a deleting request and a query request of blacklist data, and at least performing desensitization and encryption processing on part of data fields of the uploading requests; monitoring blacklist data exchange requests and responses between the sub-nodes; allocating corresponding responsibilities to each sub-node according to the monitoring result; notifying the sub-nodes which do not participate in the exchange of serving as supervisors, and verifying exchange conditions of the two exchange parties; and notifying the sub-nodes passing the exchange condition verification of performing one-to-one data exchange. The method and device solve the problems that original sensitive data sharing is high in cost and poor in data timeliness and safety.

Description

technical field [0001] The invention relates to the technical field of the Internet, and more specifically, to a method for sharing a block chain blacklist using hash desensitization processing. Background technique [0002] With the rise of big data and the Internet, data-driven technology has become one of the mainstream technologies for the development of various industries. Building data of sufficient scale is the basis of data-driven technology, but data accumulation usually consumes a lot of manpower and material resources. In response to this problem, it is undoubtedly a better solution to allow multiple institutions to share data by integrating existing data from different institutions. However, the exchange and sharing of data between different institutions has certain requirements for data security, timeliness and authenticity. Especially in the face of some sensitive data involving privacy and business secrets, such as user data such as blacklists, credit report...
