Item Ensuring the security and privacy of information in mobile health-care communication systems(South African Journal of Science, 2011-09-02) Adesina, Ademola O.; Agbele, Kehinde K.; Februarie, Ronald; Abidoye, Ademola P.; Nyongesa, Henry O.The sensitivity of health-care information and its accessibility via the Internet and mobile technology systems is a cause for concern in these modern times. The privacy, integrity and confidentiality of a patient’s data are key factors to be considered in the transmission of medical information for use by authorised health-care personnel. Mobile communication has enabled medical consultancy, treatment, drug administration and the provision of laboratory results to take place outside the hospital. With the implementation of electronic patient records and the Internet and Intranets, medical information sharing amongst relevant health-care providers was made possible. But the vital issue in this method of information sharing is security: the patient’s privacy, as well as the confidentiality and integrity of the health-care information system, should not be compromised. We examine various ways of ensuring the security and privacy of a patient’s electronic medical information in order to ensure the integrity and confidentiality of the information.Item Using Wearable Sensors for Remote Healthcare Monitoring System(Scientific Research, 2011-05-22) Abidoye, Ademola P.; Azeez, Nureni A.; Adesina, Ademola O.; Agbele, Kehinde K.; Nyongesa, Henry O.Recent technological advances in wireless communications and wireless sensor networks have enabled the design of low-cost, intelligent, tiny, and lightweight medical sensor nodes that can be strategically placed on human body, create a wireless body area network (WBAN) to monitor various physiological vital signs for a long period of time and providing real-time feedback to the user and medical staff. WBANs promise to revolutionize health monitoring. In this paper, medical sensors were used to collect physiological data from patients and transmit it to Intelligent Personal digital Assistant (IPDA) using ZigBee/IEEE802.15.4 standard and to medical server using 3G communications. We introduced priority scheduling and data compression into the system to increase transmission rate of physiological critical signals which improve the bandwidth utilization. It also extends the life time of hand-held personal server by reducing power consumption during transmission.
