Paper Abstract:	In this paper we discuss the combination of data hiding with compression in order to improve patient data management and maintainability. Data hiding is adapted here for interleaving patient information with volumetric medical images, while offering privacy and security. The image compression scheme under consideration is JP3D (JPEG2000 Part 10 standard) that gives support to volumetric datasets. The embedding is applied in the Discrete Wavelet Transform (DWT) domain, before passing through the 3D-EBCOT (three dimensional Embedded Block Coding with Optimized Truncation) algorithm. By this way, the hidden data can be detected on the fly during image decoding, or, whenever we apply the DWT to the reconstructed image. Experiments performed on a database of Magnetic Resonance and Computerized Tomography sequences show that our data hiding scheme for data hiding performs a large data payload. Furthermore, it is robust against JP3D compression attack whereas keep a relative lower distortion.
