What is MEDIS?

A blockchain-supported system aiming to enhance methods of storage, access and use of electronic health records.
MEDIS is a new approach that aspires to give control to patients over their existing medical records and health related data, while making it instantly available everywhere. The system utilizes distributed storage technology for redundancy and availability, distributed computing for access control and auditing, and strong cryptographic encryption to ensure confidentiality of the content uploaded in the form of medical records, diagnostic imaging and related information.

* All medical records are anonymized according to HIPAA requirements prior to being made available for review or download by other entities.
