Method and apparatus for managing user authentication in a blockchain network

An apparatus for authentication in a blockchain network, the apparatus comprising a hardware processor configured to:

• receive, from a user device, a request for a snapshot identifier (ID) and user data comprising Internet of Things (IoT) routine data comprising routine data and at least one of a one-time password, biometric data, context data or device metadata, wherein the routine data comprises a behavior pattern of a user performed in an IoT network that includes the apparatus and a route of the user in a predetermined area with a predetermined sequence within a predetermined time duration;
• generate the snapshot ID based on the received user data;
• transmit the generated snapshot ID to the user device;
• and
• broadcast the snapshot ID to a blockchain server for authenticating the snapshot ID by comparing the transmitted snapshot ID and the broadcast snapshot ID.

An apparatus for authentication in a blockchain network, the apparatus comprising a hardware processor configured to:

• receive a first snapshot identifier (ID) and user data comprising routine data and at least one of a one-time password, biometric data, context data or device metadata, wherein the routine data comprises a behavior pattern of a user performed in an Internet of Things (IoT) network that includes the apparatus, and a route of the user in a predetermined area with a predetermined sequence within a predetermined time duration
• included in a blockchain transaction data from a user device and broadcast in the blockchain network by a server;
• transmit a request for a second snapshot ID to a ledger in the blockchain network;
• receive the second snapshot ID from the ledger;
• determine whether the first snapshot ID corresponds to the second snapshot ID;
• and
• authenticate the first snapshot ID based on the determination.
