Enhancing security of electronic health records through grid-based user authentication scheme

摘要

Medical research and electronic health record (EHR) maintenance involves large databases that are geographically distributed which calls naturally for a grid computing environment. Huge data in medical image analysis, storage and genome processing demand large medical data storage and computing power. Data sharing, software specialisation and data processing which occur in a heterogeneous way tend to make use of the grid computing environment for the medical field. The security solution for authentication in the existing grid environment is non-scalable. This major drawback can hinder the growth of the user community in the medical field. A simple user authentication scheme is proposed, which enhances the security of the overall system but takes less time for execution and lesser communication cost.
