LOSSLESS CRYPTO-DATA HIDING IN MEDICAL IMAGES WITHOUT INCREASING THE ORIGINAL IMAGE SIZE
José Marconi Rodrigues, William Puech, Christophe Fiorio · 2004
Abstract: In this paper, a novel lossless crypto-data hid-ing method for medical image is proposed. It is based on decomposition and image contents. It can embed in-formation of the patient into the image in a high undeci-pherable way without neither increase of size nor change of original contents. The main idea is to decompose the medical image in two sub-images and to apply to each sub-image different process in order to gain space and in-formation privacy. It can be used to embed the diagnostic and/or the historical disease into medical images of the patient for safe transfer purpose.
