Database Traceability Algorithm Based On Zero Watermark

摘要

As database security issues become more and more important, copyright determination and database traceability technologies are becoming important requirements for database security. In order to trace the database at the same time of copyright determination, a database traceability algorithm based on zero watermark is proposed. In this paper, the database table is split by using the method of retaining the reference relationship, so that the database table can be traced efficiently. At the same time, a zero watermark method based on classification is applied to the split database table, so that the database is protected by copyright certification. Simulation experiments verify the good robustness and high traceability of the algorithm.
