Multiple medical image encryption algorithm based on scrambling of region of interest and diffusion of odd-even interleaved points

作者：

Highlights：

• A novel encryption scheme for multiple medical images based on ROI is proposed.

• The algorithm can be applied to gray and color images of any number and size.

• The coordinates of the ROI are set as part of the secret key.

• A new diffusion algorithm based on odd–even interleaved points is proposed.
