2. Security and confidentiality issuesSecond, the meeting point between the needs of coastal defense islands and border defense and unmanned technology1. UAV: the eye of the air in coastal defense and frontier defense.

China has a long coastline, numerous islands and vast land borders, and it is difficult for traditional monitoring methods to cover these vast areas. Unmanned technology can solve this problem well. Drones and unmanned devices can extend the monitoring range and fill the dead ends of monitoring. No matter in the waters around distant islands or in the inaccessible border mountainous areas, unmanned technology can continuously monitor and ensure that China's coastal defense islands and border defense areas are always under monitoring.Unmanned science and technology: a new boost to coastal defense islands and border defense.Unmanned driving technology can also play a unique role in coastal defense islands and border defense. At sea, unmanned ships can be used for patrol, material transportation and other tasks. In island defense, unmanned supply ships can accurately transport materials to various islands, reducing personnel risks and improving transportation efficiency. In border areas, unmanned vehicles can perform patrol tasks in harsh terrain and environment. For example, in plateau border areas, unmanned vehicles are not affected by factors such as high altitude and lack of oxygen, and can patrol for a long time according to the set route to find out the sudden situation at the border in time.
