# ChainCare



ChainCare is a health information system that uses smart contracts to handle medical procedures and stores the medical history in Block Chains.












## Features



This system provides a whole medical history of the patient since the subscribing to it, also a professional history for doctors and lab doctors. The generated data are stored automatically in electronic records forms ledgers by a blockchain platform which makes it secured and well managed. The users will be able to leverage their medical data to power many applications and services.



- Critical information is stored significantly in End-to-End encrypted records using BlockChain -Ethereum- that makes it difficult or impossible to change, or hack.

- Provides user’s privacy by managing permissions guarantee preventing unauthorized access.

- Provides high availability of information as it is stored in Block Chain which is can be accessed remotely.

- Information is organized in a time-variant and non-volatile way.

- Enables disease prediction according to the user's entered symptoms.

- Allows users to monitor other users' accounts for special cases.

- Allows users to share records with medical staff or other users.

- The system's admin can provide analytical reports and statics for a specific number of medical records.

- The system's admin can add medical staff and Assign patients to specific doctors.

- The system's admin can monitor the medical staff's activities.

- Doctors can provide full professional history for them.

- Doctors can provide an overview of the patient’s situation.

- Lab staff can allow remotely receiving required medical tests and uploading the results.
