Research on Information Security Release Scheme of Metro Intelligent Passenger Service

In order to ensure the security of service information release in metro, an information security release scheme was proposed at the software level based on the center and station control structure of passenger information system, considering the whole progress of editing, auditing, storage, transmission and display. Operation identity audit was realized through the face recognition technology and information encryption was realized through a hybrid encryption technology based on China commercial cryptographic algorithm. The scheme improves the reliability of information sources, privacy of data, security of operation, and avoids potential risks caused by illegal and politically sensitive information displayed on the terminal screen due to account leakage and data tampering and other malicious acts.
