Malta Systems, a healthcare technology company focused on unique, absolute, and interoperable healthcare identity, announced the approval of their patent titled, “Anonymous authentication using backup biometric information,” US patent number 9,213,818.

Malta Systems’ CEO, Don Brown is pleased with the approval of the patent. “By implementing Privasent’s patented technology, providers have an identity foundation necessary to link patient EHRs precisely throughout the continuum of care — regardless of where that care is provided — and improve both patient satisfaction and care. With the patient as the focal point, hospital clinical, financial, medical records and technology teams can work with the Malta team to demonstrate the clinical and financial benefits of absolute healthcare identity,” Brown said.

Privasent’s patented solution combines smart card, biometric and security technologies to produce a unique, absolute and interoperable identity that can scale to a national patient identifier. This unique identity can only be used to access healthcare services thus protecting the patient’s privacy and identity integrity. Patients are registered in the Privasent network with the issuance of a Privasent card and the capture of a palm-vein pattern. Each time a patient checks-in for care, Privasent validates their identity and the electronic health record (EHR) associated with the identity. Healthcare providers can search Privasent to identify other EHRs associated with this identity throughout Privasent’s network of providers and determine which must be accessed to provide relevant medical history for the patient’s care. The awarded patent covers managing the use of such a physical token — in this case a smartcard — together with a biometric identifier — here, a simple palm-vein scan — to uniquely and quickly identify every patient.

The newly awarded patent is essential to helping Malta Systems provide absolute patient identity with Privasent. It covers a biometric template that is encrypted with an additional key pair (the first key pair is held securely by the individual who provided the biometric template). The private key of this additional key pair is held in escrow — not by one party, but by several independent entities — using a secure key-sharing algorithm. This way, the biometric template cannot be decrypted without collaboration between these independent entities.


About Malta Systems

As a wholly-owned subsidiary of Partnet, Malta Systems is backed by a decades-deep background in Internet innovation. A near tragedy changed the company’s course when Don Brown, Malta Systems President and founder, had a personal encounter with electronic health records and their lack of portability. In 2011, his wife was seriously injured in an accident located far from their home medical center. In the height of the emergency, progress was halted when the doctors were unable to confirm the accuracy of her medical records.

Precious time slipped by while the team resorted to guesswork by family members for answers to essential questions like what medications she might be taking. The lack of an electronic medical record that was positively associated with her nearly ended in tragedy. However, thanks to excellent teams in air medical and shock trauma, she has now fully recovered. That harrowing event was the impetus for Privasent. Dr. Brown turned his team’s attention to the problems with EHRs and they responded with a groundbreaking innovation designed to prevent experiences like this and save lives worldwide.
