An Australian startup is using blockchain to boost security in the health care system, Blockchain News reports. Brontech has created the health platform Cyph MD to build secure digital identities using blockchain technology. Brontech co-founder Emma Poposka said countries around the world, including Australia, have fragmented data sharing systems, making it difficult for a medical staff to communicate patient data. “Cyph MD leverages asymmetric cryptography, which is the use of private and public keys to encrypt and decrypt data,” said Poposka. “The asymmetric cryptography is paired with a hierarchical certificate system so that every health care provider can issue ‘identity tokens’ to its practitioners who have been digitally signed by the hospital. This allows for communication between different stakeholders within the health care sector.” Editor’s Note: The IAPP will be hosting a discussion on sharing sensitive health data in the U.S. at the Privacy. Security. Risk. conference from Sept. 13-16, in San Jose, California.
