Cisco applied for a patent by the U.S. Patent and Trademark Office on Thursday
The application can identify different connected devices, monitor their activity and evaluate how trustworthy the device is when connected to a network.


Abstract

In one embodiment, a device in a network receives a network registration request from a particular node. The network registration request comprises information about the particular node. The device causes performance of a validation of the information about the particular node via comparison of the information about the particular node to a distributed block chain that includes information regarding the particular node and one or more other nodes. The device causes an update to the block chain based on the information about the particular node and the validation of the information about the particular node. The device uses the updated block chain to control behaviour of the particular node and the one or more other nodes.
