Encrypt Anything: A Content‐Aware Hierarchical Privacy Protection Method for Image Data

IET Computer Vision, Volume 20, Issue 1, January/December 2026.
This paper proposes the Encrypt Anything Model (EAM), a content‐aware hierarchical privacy protection method that integrates the Segment Anything Model (SAM) and Grounding‐DINO to automatically detect and segment privacy entities in images. EAM dynamically adjusts the encryption granularity according to the sensitivity level of privacy and introduces a

Safe and Quickest Medical Image Encryption Using Logistic Map Derived S‐Boxes and Galois Field

Computational and Mathematical Methods, Volume 2026, Issue 1, 2026.
The pseudorandomness, simplicity of use, and extreme sensitivity to even the slightest change in the initial value and handling parameters make chaotic maps attractive. The use of medical imaging to diagnose illnesses has grown in significance. These photographs need strong security measures because they are exchanged over public networks.
