Enhancing the Security for Healthcare Data using Blockchain Technology

Abstract

Cyber security is the safest way to protect the data from hackers and unauthorized users. Healthcare technologies nowadays face lots of cyber security issues related with the security of the health information and privacy of the data. Cyber security is one of the popularized ways to protect the data from hackers and spammers. HealthCare is the field where the data is highly sensitive and the security for the systems is low. Protecting the sensitive data is achieved by the blockchain method, which is similar to a database but the difference is the data stored in the blockchain in blocks. The new blocks included are connected to previous blocks from a chain like structure, it is very secure, each block stores data and also the hash of previous blocks. So, data cannot be easily accessed or manipulated. The mechanism used in blockchain for the security of the data consensus mechanism which contains the different methodologies includes Proof of Work (PoW), Proof of Stake (PoS), Proof of Space and Proof of Authority. Enhanced proof of stake is a combination of the PoS and DPoS used to increase the security of the system by eliminating the 51% attack in blockchain and reduces the data theft threats and protects the medical records of patients from hackers.
