Research on the Watermarking Algorithm Based on Numerical Attribute in the Relational Database
Ying Wang, Gengming Zhu, Shaobo Zhang · 2012
This paper presents a kind of watermarking algorithm based on numerical attribute in the relational databases. The watermarking is embedded by the Arnold transforming and scrambling technology and modifying the parity of the low decimal number of numeric attribute, connected with some attribute in the physical storage space in the relational databases. This algorithm may achieve the purpose of copyright protection of database effectively because of the strong robustness.
