Ally Medina, director of the Blockchain Advocacy Coalition in California, said that using verifiable credentials could be the solution. With this model, patients are the only people with access to information.
Verifiable credentials are the digital form of physical identification. Exchanging health records using verifiable credentials ensures health records have been transferred from doctor to patient. It does not store the record itself, making it an advocated option for new health tech companies.
Third parties holding personal information spark cybersecurity concerns, but verifiable credentials make hacking more difficult. The most recent technology developments are for proof of Covid-19 testing or vaccination.
