Blockchain AND Electronic Medical Records EMR in Cloud Environments
Blockchain & Electronic Medical Records (EMR) The journey of medical data to cloud-based platforms has smoothened the sharing process of medical data between healthcare and other research-based institutions, thereby enhancing the easy exchange of information nowadays. Electronic Medical Records (EMR) is critical sensitive personal information which needs to be constantly shared among network for diagnosis and treatment. The critical sensitive patient record captures information on demographics, analysis, vital cryptogram, precedent medical history, and advancement over time, and more. This patient record sharing network includes pharmacies, healthcare providers, insurance companies, researchers, patient parties etc. Healthureum’s Blockchain based technology is the platform where sharing irreversible transactions can be easily done with accountability and reliability. Sharing and also storing data among multiple networks requires major challenges for maintaining the authenticity of the shared data without undergoing any malicious activity. A patient who is undergoing a serious medical ailment is under prolonged treatment, monitoring, and rehabilitation process. Such patient has huge medical data record accumulated throughout the treatment process and those records need to be accessed by the various network without getting any changes or damage else the patient has to undergo major problems in the treatment procedure. At times such patient has to transfer to other hospitals or referred in another city, country for further treatment, hence maintaining the previous health information record is a must. Here the process of sending data is cumbersome and time taking if done by post. Sending data by internet is also not reliable, for security issues. Here Healthureum, Electronic Medical Records (EMR) plays a major role in transferring data anywhere securely through the cloud environment. Initially, the data transfer depended on a centralized entity which would store patient information and access control policies were defined but the single place for failure could spoil the functioning of the data transfer and things would turn tedious again. This process also entailed performing the procedure over encrypted data and selecting a trusted individual who will have access to the secure data. This process was very difficult to manage without any bottleneck. Healthcare sector acceptance to Healthureum blockchain technology has provided advantages of association which range from achieving new insights into existing treatments, analyzing new treatments, and enhanced execution of masshealth. Electronic Medical Records (EMR), incorporates a set of an immutable transaction which is performed amidst the group of a connected network. This becomes possible by employee consensus protocol and cryptographic functionality namely digital signature and hash tagging. The Healthureum blockchain steadily stores health accounts and preserve a single edition of the truth which is irreversible. Diverse medical organizations and folks namely doctors, hospitals, insurers and labs – can demand consent to use a patient’s record from the blockchain. Patients, thus have more power over who sees their data, while healthcare providers can offer improved patient care for getting accurate data. Process Flow of Blockchain & Electronic Medical Records (EMR), in Cloud Environments Data generating is easier, where even the patient’s wearable device can produce data, a doctor could inscribe a note to the blockchain, or a pharmacist could distribute medicine. The data is in encrypted form and is provided a unique identity, stored on the patient’s blockchain. Now, this data is transmitted to cloud storage. When Data is requested by any of the stakeholders, the ID on the blockchain is put to regain the encrypted data. Lastly, the data is decrypted, and then shown on the relevant device or application. Blockchain & Electronic Medical Records (EMR), basic benefits to patients and healthcare providers: Data can only be accessed by the patient’s confidential key; even if the database is hacked, or any malicious activity occurs, the patient’s data will be illegible due to encryption. Patients have full power to access their healthcare data and can monitor who sees their data when they are seeing and at what point of time data is accessed. Immediate transfer of data, where all member of the scattered network of the healthcare blockchain will possess the same data for the patient which reduces the risk of errors and helps in better care of patients. Conclusion The use of Healthureum blockchain also enables a reduction in overhead costs, particularly for development and maintenance of legacy health record systems. Successful deployment of blockchain for health records allows data transition between related parties in an efficient, consensus-based, seamless manner. The health metadata blockchain and EMR systems in Healthureum encompass a holistic explanation the explanation that facilitates secure exchange of EMR data and conquers incompatibilities among systems. With the EMR metadata blockchain, each provider, patient, health system, medical device, records, et.al can be a part of the network. The irreversible quality of the blockchain community ledger ascertains none can modify the providers EMR after the truth. Every digital signature is acknowledged by stakeholders, data transactions in a blockchain will rationalize the process of creating precise research datasets by preventing information disintegration and enabling record merging. Blockchain technology can track admittance to every EMR, given that an immutable audit trail of the record is used every time.
