4. Nowadays in healthcare field, increased use of computerised care delivery system is available . It helps to conserve time and energy of healthcare providers and also ensure the safety of data for a long periods. Such computerised system helps to access patient details easily in case of any emergency. It reduce the use of paper file.

Electronic medical records (EMRs) are a digital version of the paper charts in the clinician’s office. An EMR contains the medical and treatment history of the patients in one practice. EMRs have advantages over paper records. For example, EMRs allow clinicians to:

  • Track data over time
  • Easily identify which patients are due for preventive screenings or checkups
  • Check how their patients are doing on certain parameters—such as blood pressure readings or vaccinations
  • Monitor and improve overall quality of care within the practice

But the information in EMRs doesn’t travel easily out of the practice. In fact, the patient’s record might even have to be printed out and delivered by mail to specialists and other members of the care team. In that regard, EMRs are not much better than a paper record.

Electronic health records (EHRs) do all those things—and more. EHRs focus on the total health of the patient—going beyond standard clinical data collected in the provider’s office and inclusive of a broader view on a patient’s care. EHRs are designed to reach out beyond the health organization that originally collects and compiles the information. They are built to share information with other health care providers, such as laboratories and specialists, so they contain information from all the clinicians involved in the patient’s care. The National Alliance for Health Information Technology stated that EHR data can be created, managed, and consulted by authorized clinicians and staff across more than one healthcare organization.

6. Cryptography is otherwise known as secret writing. It is the process of coding and decoding information.

Cryptography is important in medical field as . E-health, Telemedicine are using it which are Important properties for designing encryption schemes for medical data applications. Also Image encryption is one of the important fields of cryptography. Medical image data is a central part of diagnostics in today's healthcare information systems. With the adoption of cloud computing approaches in the healthcare sector by most health care system
