Patent attributes
An authentication device that includes a memory operable to store a behavior signature for a user and a distributed ledger comprising information for a private blockchain and a semi-private blockchain associated with the user. The network device further includes an authentication engine implemented by a processor. The authentication engine is configured to receive an authentication request for a network resource and to determine a resource classification type based on the network resource. The authentication engine is further configured to identify one of the private blockchain and the semi-private blockchain based on the resource classification type and to extract data from one or more blocks in the identified blockchain. The authentication engine is further configured to determine at least a portion of the extracted data matches the stored behavior signature for the user and to provide access to the network resource in response to the determination.
