Application Analysis of Data Leakage Prevention Technology in Power Enterprise Informatization Based on Encryption Algorithm

This paper proposes a hybrid leakage prevention model based on the combination of encryption algorithm and watermark technology, aiming to improve the data security and leakage prevention capabilities in the information system of power enterprises. By improving the symmetric encryption algorithm (such as AES) and combining it with digital watermark technology, the model proposed in this paper not only improves the data encryption efficiency, but also strengthens the traceability capability after data leakage. The experimental simulation results show that the improved encryption algorithm improves the encryption efficiency by about 15% compared with the traditional method, and the data leakage tracing accuracy combined with watermark technology is improved by 20%. This model can effectively cope with the real-time requirements of the big data environment of power enterprises, ensure data security, and provide effective source tracing when data leakage occurs. Research shows that the hybrid leakage prevention technology based on the combination of encryption and watermark has broad application prospects, especially in the information system of power enterprises, which can significantly improve the data protection level.
