Smart devices, mobile Internet, and Cloud services contribute to the continuous and systematic innovation of Healthcare and enable cost-effective, efficient, timely, and high-quality ubiquitous medical services.
"Pervasive healthcare applications generate a vast amount of sensor data that have to be managed properly for further analysis and processing."
The adoption of Cloud in this scenario leads to the abstraction of technical details, eliminating the need for expertise in, or control over, the technology infrastructure, and it represents a promising solution for managing healthcare sensor data efficiently.

It further makes mobile devices suited for health information delivery, access and communication, also on the go, enhancing medical data security, availability, and redundancy.
  • Moreover, it enables the execution (in the Cloud) of secure multimedia-based health services, overcoming the issue of running heavy multimedia & security algorithms on devices with limited computational capacity and small batteries.
  • In this field, common issues related to management, technology, security, and law have been investigated: interoperability, system security, streaming Quality of Service (QoS), and dynamically increasing storage are commonly considered obstacles.
The IT skills greatly you need are
  • Data analytics
  • Cloud computing
  • Smart devices applications
  • Security
