Mercer and co-author Anjum Khurshid, M.D., Ph.D., say blockchain holds great potential as “techQuity”– technology that provides innovative solutions to advance health equity. Blockchain is a decentralized, digital ledger system that uses encryption to share information or transactions across a network of computers. Once verified, each “block” of new information is linked to the existing block, creating a chain of secure data that a person can access anytime, anywhere.
“The architecture of blockchain technology makes it a unique solution for managing identities of vulnerable people, allowing them to secure their information and control when and where that data gets shared,” said Khurshid, director of data integration in Dell Med’s Department of Population Health. “For instance, if you need to prove you’re over 18 years old, that information can be validated through blockchain without having to share your driver’s license.”
