Information Security Technology Based on Remote GPS Data Acquisition System

In the existing system to add security technology, this paper makes the existing system more practical, the purpose is to achieve the VPN virtual private network function, so that the transmitted data can be safely transmitted on the Internet. Based on the principles of the Internet Protocol Security (IPsec), the System connects existing Global Positioning System (GPS) data to the virtual private network so that GPS data can be transmitted securely. It can send and receive data using serial interface, and can transmit data across the network. Through the design of the database, it can understand how to write the database, and how to use the remote terminal to read the database data. In this paper, the password policy success rate is 93%, and the data backup strategy success rate is 92%. This paper is of great significance to improve the level and technical level of water traffic safety information system.
