Hadoop-Based Healthcare Information System Design and Wireless Security Communication Implementation

Abstract EN

Human health information from healthcare system can provide important diagnosis data and reference to doctors.

However, continuous monitoring and security storage of human health data are challenging personal privacy and big data storage.

To build secure and efficient healthcare application, Hadoop-based healthcare security communication system is proposed.

In wireless biosensor network, authentication and key transfer should be lightweight.

An ECC (Elliptic Curve Cryptography) based lightweight digital signature and key transmission method are proposed to provide wireless secure communication in healthcare information system.

Sunspot wireless sensor nodes are used to build healthcare secure communication network; wireless nodes and base station are assigned different tasks to achieve secure communication goal in healthcare information system.

Mysql database is used to store Sunspot security entity table and measure entity table.

Hadoop is used to backup and audit the Sunspot security entity table.

Sqoop tool is used to import/export data between Mysql database and HDFS (Hadoop distributed file system).

Ganglia is used to monitor and measure the performance of Hadoop cluster.

Simulation results show that the Hadoop-based healthcare architecture and wireless security communication method are highly effective to build a wireless healthcare information system.
