Lossless Data Hiding for Medical Images with Patient Information
Sang-Kwang Lee, Seong‐Jae Lim, Young‐Ho Suh, Yo‐Sung Ho · 2007
This paper presents a lossless data hiding algorithm for medical images, where we embed the patient information into the segmented liver region of the CT image. This algorithm utilizes the characteristics of difference images and modifies pixel values slightly to embed a large amount of data while keeping high visual quality.
