Blockchain technology has the potential to help deliver more efficient health
services, improving patients’ experience from end to end. In this chapter, a blockchain
platform is analyzed, which adopts a protocol that is designed to both regulate access to
data and information, digitize health data, and enable an untrusted reader to ask for the
execution of arbitrary algorithms on the peer's private databases, whose contents must
remain hidden to those who are not authorized to access them, and obtaining an
efficient and scalable response. The chapter uses blockchain technology to enhance
electronic health records and patient data management. Several standardized
technologies and models are available in the market for electronic health records, but
the users, i.e., patients and hospitals, trust and believe in those services that provide
enhanced security to their data. Blockchain can be utilized for securing EHR by
deploying attributes of a public or private blockchain, enabling permission access by
hospitals and granting access easily to patients and family members.
