Blockchain: Revolutionizing Medical Data Security
Medical data–contained in complex, unaltered systems are prone to cyber attacks, potentially endangering a person’s life. How do healthcare companies protect the medical data during such scenarios? Blockchain, the growing form of cryptocurrency, provides enhanced accountability, transparency and security compared to the legacy systems. Unsecured and unpatched networks give way to blockchain technology for a more efficient way to secure the medical and healthcare data, which is valuable in many ways, from hackers and ransomware attackers.
Unlike the outdated legacy systems that consist of a single database, blockchains are distributed ledgers, unsusceptible to data losses and external attacks. The data stored in a blockchain system is encrypted, well synchronized and secured with backups of all the personal information without directly involving the patient. The medical data, if stolen by a ransomware can be very troublesome - requiring the organization or an individual to pay bitcoins for reacquiring the data. This problem can be eradicated with the multiple layers of security and data encryption delivered by blockchain technology, making it difficult for the hacking software to gain access.
Reshaping the healthcare and medical architecture–both on industrial and global scale-with blockchain technology opens windows to innovation and rapid scalability of security measures. Introduction of blockchain technology has made a distribution, encryption, and replication of data easy, promising efficient data sharing, data integrity, and data security. The electronic health records (EHRs) protected by the blockchain technology can give out a single patient record to be accessed by healthcare organizations all across the globe, making this form of cryptocurrency a key player for adoption and standardizing the medical and healthcare organizations.
