Abstract:

An example operation may include one or more of generating, by a data management node, a profile token based on a data profile of a data provider (DP) node, receiving, by the data management node, a transaction request from a service provider (SP) node to access data from the DP node over a blockchain, acquiring, by the data management node, consent of the SP node based on the profile token, generating, by the data management node, a consent token based the consent of the SP node, and allowing access to data of the DP node by the SP node based on a verification of the consent token.
