Using mobile phones for providing healthcare services - known as mHealth - can also be regarded as part of eHealth.

As electronic technology faces danger from cybercrime, since 2011, there has been a greater awareness for increasing security and addressing privacy concerns with regards to usage of newer modes of technology in the field of healthcare.
