This invention provides a method and system for secure image transmission and storage suitable for unmanned aerial vehicle (UAV) remote sensing platforms. The system is characterized by: a UAV subsystem acquiring video frames or image data via UAV equipment, performing lightweight encryption, and embedding verification information; a cloud platform storing the data; and a user subsystem decrypting the cloud platform data by verifying user information and retrieving it to the user's end. This method and system can encrypt video frames or image data acquired by the UAV into multiple sub-data units before transmission. Even if some sub-data units experience packet loss or errors during transmission, the original video frames or images can still be recovered using the remaining sub-data units, effectively enhancing transmission fault tolerance. Furthermore, the data transmitted and stored on the cloud platform is encrypted; each encrypted data unit contains no information about the original data, and data can only be retrieved after user verification, effectively ensuring data storage security.
