INDUSTRIAL SECURITY OUTFLOW PREVENTION BASED ON BIOMETRIC AUTHENTICATION IN CCD SURVEILLANCE SYSTEM

摘要

PURPOSE: A biometric authentication-based industrial technology leakage preventing method in a surveillance system is provided to reduce cost required for authentication by calculating the digest of a packet for authentication. CONSTITUTION: An industrial secret is transmitted through a network. All the transmitted packets are authenticated in real time. Packets containing the industrial secret are blocked through the authentication. Bio-information of a user is inserted into a transmission control protocol/internet protocol (TCP/IP) stack. A surveillance system prevents information leakage through the network.
