Secure cloud-based medical data visualization

Abstract

Outsourcing the tasks of medical data visualization to cloud centers presents new security challenges. In this paper, we propose a framework for cloud-based remote medical data visualization that protects the security of data at the cloud centers. To achieve this, we integrate the cryptographic secret sharing with pre-classification volume ray-casting and propose a secure volume ray-casting pipeline that hides the color-coded information of the secret medical data during rendering at the data centers. Results and analysis show the utility of the proposed framework. © 2012 ACM.
