DECENTRALIZED SECURE DATA SHARING

Abstract:

An example operation may include one or more of registering, by a data sharing node, a first service node and a second service node for accessing a common data store, causing, by the data sharing node, a first client node associated with the first service node to provide a data access request token key and a receipt key to a second client node associated with the second service node based on a data access request received from the second client node, assigning, by the data sharing node, weights to the data access request token key and to the receipt key, and causing, by the data sharing node, the second service node to retrieve a result from the data source based on the assigned weights.
