Abstract: A method for utilizing a block chain infrastructure to define a trusted circle including at least two nodes of a plurality of nodes, the method includes receiving, by a first node, notification information identifying a trusted user circle including the first node and a second node, wherein the first node and the second node are configured to define a private block chain; and maintaining private block chain data within the trusted user circle according to pre-defined settings, wherein the private block chain data is divided between nodes of the trusted user circle based on the pre-defined settings.
