Research on Image Steganography for the Instant Messaging and Broadcasting in a Collaborative Unmanned Cluster
Guobin Hao, Guobin Fu · 2023
For the unmanned platform collaborative operation, the communication between each platform or the broadcasting in the cluster is easy to be eavesdropped and stolen, which leads to the secret leakage and even threatens the security of the operation platform. The communication in the cluster requires to remain real-time as the steganography apply well. In this paper, an image steganography-based encryption scheme for navigation and detection information is newly designed for unmanned platform clusters. Several common image steganography algorithms such as J-UNIWARD, HUGO, WOW and LSB, are used to analyze the impact of image steganography on the performance of collaborative navigation and visual odometer positioning. After simulation and experimental verification, the feasibility of image steganography in collaborative navigation and detection in clusters is proved, and it is also pointed out that the time-delay difference between steganography and decryption will bring large errors to collaborative localization.
