Video conferencing applications help people communicate via the Internet and provide a significant and consistent basis for virtual ***,integrity,security,identification,and authentication problems are still *** video conference technologies typically rely on cloud systems to provide a stable and secure basis for executing tasks and *** the same time,video conferencing applications are being migrated from centralized to decentralized solutions for better performance without the need for third-party *** article demonstrates a decentralized smart identification scheme for video conferencing applications based on biometric technology,machine learning,and a decentralized hash table combined with blockchain *** store users'information on a distributed hash table and transactional events on the distributed ledger after identifying users by implementing machine learning ***,we leverage distributed ledger technology's immutability and traceability properties and distributed hash table unlimited storage feature to improve the system's storage capacity and immutability by evaluating three possible *** experimental results show that an architecture based on blockchain and distributed hash table has better efficiency but needs a longer time to execute than the two other architectures using a centralized database.
