A digital watermarking tool for secure distribution and traceability of power data

With the development of energy Internet and smart grid, the amount of power system data has increased rapidly, which is of great significance for optimization and scientific research. However, the widespread distribution and strong real-time nature of data also bring serious security risks. This article proposes a power data security distribution and traceability tool based on digital watermarking technology to meet the needs of secure sharing and traceability of power data. This tool utilizes digital watermarking technology to preprocess power data, ensuring data availability while achieving secure distribution and supporting efficient and reliable data flow traceability. The experimental results show that the tool can achieve secure distribution while ensuring data availability, and support efficient and reliable data stream traceability. The tool performs well in data integrity and traceability, and even under high-intensity interference, the success rate of watermark extraction remains above 85%.
