  Digital instruments play a vital role in our daily life. It is a routine to
produce business papers, watch the news program, write articles and blogs,
manage healthcare systems, to purchase online, to send messages and all this is
processed by making observations and then manipulating, receiving and availing
the diverse data. This electronic data provides the foundation of real time
data. All this transmission of data needs to be secured. Security is essential
for healthcare systems as the present one where the blood pressure recordings
provided by the smart bracelet are sent to the user's mobile phone via
Bluetooth. The bracelet monitors the pregnant women, but also other users who
wish to have their blood pressure under control. The system's server analyses
the recordings and announces the user, as well as the associated persons to the
user in case of an emergency. The doctors, the medical staff, user and user's
family and caregivers have access to the health recordings belonging to the
monitored user. Security is a main feature of the electronic healthcare system
based on the smart bracelet.
