Implementing Operations Support Systems in E-Health Based Systems
Information and communication technologies have been introduced in different dimensions
of the health care. e-Health is the use of advanced communications technologies such as
the Internet, portable, wireless and other sophisticated devices to support health care
delivery and education. It has the potentials of improving the efficiency of health care
delivery globally.
With the increasing demand for information at the point of care, health care providers
could explore the advances provided by mobile technologies and the increasing
capabilities, compactness and pervasiveness of computing devices to adopt operations
supports systems (OSS) in e-Health based systems in order to provide efficient services and
enhance their performances.
In this paper, we present, the development and implementation of operations supports in e-
Health based systems. The system promises to deliver greater productivity for health care

Fingerprinting Smart Devices Through Embedded Acoustic Components
The widespread use of smart devices gives rise to both security and privacy
concerns. Fingerprinting smart devices can assist in authenticating physical
devices, but it can also jeopardize privacy by allowing remote identification
without user awareness. We propose a novel fingerprinting approach that uses
the microphones and speakers of smart phones to uniquely identify an individual
device. During fabrication, subtle imperfections arise in device microphones
and speakers which induce anomalies in produced and received sounds. We exploit
this observation to fingerprint smart devices through playback and recording of
audio samples. We use audio-metric tools to analyze and explore different
acoustic features and analyze their ability to successfully fingerprint smart
devices. Our experiments show that it is even possible to fingerprint devices
that have the same vendor and model; we were able to accurately distinguish
over 93% of all recorded audio clips from 15 different units of the same model.
Our study identifies the prominent acoustic features capable of fingerprinting
devices with high success rate and examines the effect of background noise and
other variables on fingerprinting accuracy
