The revolution of blockchain technology has matured enough to substantiallydisrupt the healthcare sector, in terms of security, privacy, and data exchange.Citizens have ceased to trust third-party organizations for storing their personaldata, due to the numerous data breaches and illegal exchanges occurring everyyear. These major issues have given birth to a brokerage and market platformfor personal data utilizing blockchain technology, giving users the ability to buyand sell personal health and educational data in a permissioned network. Dataowners set specific policies determining who can have access to their data, how, and for what purpose. Data exchange validations are handled by smart contracts reliably enforcing access control by verifying buyers’ purposes of usage against data policies. The platform does not store sensitive data itself, inspiring trust to users by handing them exclusive control of their data. The smart contracts ensure that a user’s sharing consent is always in control of the transaction output decision. As a result, users are incentivized to share their medical data for any purpose in a reliable and legal compliant manner.
