IoT is used in a variety of devices that enhance the quality of the healthcare services received by the patients.

Even the existing devices are now being updated by IoT by simply using embedding chips of smart hospital devices. This chip enhances the assistance and care that a patient requires.


Data security & privacy

One of the most significant challenges in healthcare that IoT poses is of data security & privacy. IoT security devices capture and transmit data in real-time.


However, most IoT devices lack data protocols and security requirements.

In addition to that, there is significant ambiguity regarding data ownership regulation with electronic devices.

All these factors make the data highly susceptible to cybercriminals who can hack into the system and compromise Personal Health Information (PHI) of both patients as well as doctors.

Cybercriminals can misuse patient’s electronic health record to create fake IDs to buy drugs and medical equipment which they can sell later.

Hackers can also file a fraudulent Insurance claim in patient’s name.
