2. Security and confidentiality issues1. UAV: the eye of the air in coastal defense and frontier defense.Summary: Unmanned technologies such as unmanned aircraft, unmanned driving, unmanned shops, unmanned hotels and unmanned banks have provided a new source of strength for coastal defense islands and border defense to defend the motherland. They have many points of convergence with the needs of coastal defense islands and border defense, and can play a great role in monitoring, dangerous task execution and logistics support. Although it is faced with challenges such as adaptability to complex environment and security and confidentiality in the application process, unmanned technology will be able to better serve coastal defense islands and frontier defense by developing protection technologies and strengthening confidentiality management, and make important contributions to defending the territorial integrity and frontier security of the motherland.

Second, 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.The logistics support of coastal defense islands and border defense areas is facing problems such as long distance and difficult transportation. The services provided by unmanned technology such as unmanned shops, hotels and banks are helpful to improve the efficiency of logistics support. Through the automatic replenishment system of unmanned shops, the island garrison can obtain the needed materials in time; The fast check-in and check-out system of unmanned hotels facilitates the accommodation arrangements of people passing by; The self-service of unmanned banks ensures the safe and convenient use of funds and provides a solid logistical foundation for security work.
