| Popis: | Video-GIS data, a novel generation of multimedia produced through the integration of geographic videos and GIS, has evolved into an innovative form of geospatial data representation. As a kind of digital products, Video-GIS data is vulnerable to unauthorized replication, dissemination, and usage. The potential for large-scale leakage of sensitive or confidential information, including commercial, political, military, and personal privacy data, poses a significant threat to the rights of data producers and may even compromise national security. Given this context, the primary concern is ensuring the security protection of video data in an open and shared data environment. To address this issue, we propose a novel scheme for the security protection of Video-GIS data in this paper, which collaboratively utilizes digital watermarking and data encryption. In the proposed scheme, Video-GIS data is divided into two categories, i.e., general and confidential, based on the presence or absence of sensitive information within the image frames. Appropriate security measures were meticulously designed for each data type to ensure effective prevention and control. Experimental results indicate that this watermarking algorithm exerts minimal influence on the quality of the Video-GIS data, while simultaneously maintaining optimal invisibility and robustness. The employed audio denoising method is characterized by its low complexity, simplicity, and feasibility, thereby ensuring the security of audio signal storage and transmission. This approach effectively realizes the dual protection objective for Video-GIS data, audio, and video. |
