A novel zero-watermarking scheme with enhanced distinguishability and robustness for volumetric medical imaging

作者：

Highlights：

• An improved lossless zero-watermarking is proposed for volumetric medical imaging.

• Ring statistics are designed to ensure the distinguishability and robustness.

• Intra-slice variations are deployed to enhance the watermarking distinguishability.

• A logistic-logistic based chaotic system is used to ensure the watermarking security.
