摘要：

In order to protect the copyright of relational database data, a watermark embedding algorithm based on FCM clustering is proposed. When embedding, the embedded watermark data is filtered by the clustering algorithm, and then embedded by the user key watermark. The algorithm can only extract the watermark if it has the key and the secret clustering parameters. The experimental results show that the accuracy of watermark extraction is high, and the algorithm is also excellent in security and concealment. Even in the case of key leakage, the security of the database can be guaranteed.
