Threats to the transmitted data : Wireless communication
ranges are not confined, and are easily vulnerable. In
wireless healthcare applications, medical devices sense the
patient and environmental data, and send it either to the
physician or the hospital server. While sending PHI to the
system, it may be attacked. For example, an adversary can
capture the PHI data from the wireless channels, and can
alter the data. Later, he/she may pass the attacked data to
the physician or EHR server, which could endanger the
patient. There are various types of transit attacks including
interception, modification and insertion.
