HQR-Scheme: A High Quality and resilient virtual primary key generation approach for watermarking relational data

作者：

Highlights：

• The proposed metrics help to know if a VPK set will be useful to watermark the data.

• There is no need to perform the WM embedding to know if the VPK set is good.

• The cyclic idea of the attribute order helps to design an effective VPK scheme.

• The WM is detected even after being deleted more than one attribute of R.
