Blockchain For Healthcare
Healthcare is a data intensive domain where a huge amount of data is created, which is access and stored daily. Data captured in the paper format is hard to capture in system as well expensive to archive, and being available when required. These challenges may lead to health decisions not made with absolute information, due to missing information there is need for repeated tests or data being stored in a different hospital at a different state or country. This highlights the need of a secured system. The proposed system has the potential to use the Blockchain technology to protect healthcare data hosted within the cloud. Electronic Medical Records (EMRs) contain medical and clinical data related to a given patient and stored by the responsible healthcare provider by using the proposed system. The individual or hospital authority facilitates the retrieval and analysis of healthcare data. The proposed system is a web-based application where user can register and get their unique key.With the help of unique key patient can itself upload patient’s data on cloud as well by giving permission to hospital authority they can also view patient’s data. By connecting two or more hospital, hospitals can share their patient’s data for further treatment. They can share patient’s data only if patient has given the right when he/she wants to transfer their medical history to other doctor. Change in data will be reflected to all hospitals in network. For this web-based interface user only has to make use of their Aadhar card number for registration and login purpose, no need of having hospital membership.
