The embodiment of the invention provides a data right confirmation method based on a block chain network and a related device. The method comprises the steps of: enabling a first block chain node in the block chain network to send or receive communication information; recording the communication information in an account book of the block chain network, wherein the plurality of block chain nodes in the block chain network comprise a using node and a providing node, the using node is used for requesting user credit data corresponding to the user identifier from the providing node according to the service request carrying the user identifier, the providing node is used for providing user credit data for the using node, the communication information comprises information between the first block chain node and other block chain nodes or a user client, and the user client is used for sending a service request carrying a user identifier to the use node, and / or is used for determining whetherthe providing node is allowed to provide user credit data corresponding to the user identifier to the use node. According to the invention, the security of user data can be improved.
Description
technical field [0001] This application relates to the technical field of block chain, in particular to a data right confirmation method and related devices based on block chain network. Background technique [0002] With the development of information technology, people's daily life is more and more closely integrated with the digital world. When a user needs to apply for a business service from some business service provider in daily life, the business service provider needs to check the user's personal information to determine whether to provide the user with the business service applied for by the user. For example, a bank can provide users with various types of financial services. After accepting a user's business request, the bank needs to obtain credible user data from a third-party data provider, so as to confirm whether to provide the user with corresponding financial services based on the obtained user data. Serve. Third-party data providers can pre-record user d...
