TRACKING DATA TRANSFERS

An embodiment of the invention relates to tracking data transfers. An example operation may include one or more of connecting, by a data owner node, to a blockchain network that includes a plurality of storage provider peer nodes associated with a plurality of cloud storage providers, selecting, by the data owner node, storage provider peer nodes of the plurality of the storage provider peer nodesto be approved storage location member nodes, and executing, by the data owner node, a smart contract to: store data on the cloud storage providers of the plurality of the cloud storage providers associated with the approved storage location member nodes, and record movement of the data to the cloud storage providers on the blockchain. 本公开的实施例涉及追踪数据传输。示例操作可以包括以下操作中的一个或多个：由数据拥有者节点连接到区块链网络，区块链网络包括与多个云存储提供方相关联的多个存储提供方对等节点；由数据拥有者节点选择多个存储提供方对等节点中的存储提供方对等节点以作为批准的存储位置成员节点；以及由数据拥有者节点执行智能合约以：将数据存储在多个云存储提供方中与批准的存储位置成员节点相关联的云存储提供方上，并且将数据到云存储提供方的移动记录在区块链上。
