Privacy engineering designs systems for managing personal information. Privacy by default is a method that aims to keep personal information from being used or shared whenever possible.

Our current demonstrations of privacy engineering are:

An independent patient controlled health record called Trustee by HIE of One (Health Information Exchange of One). This is an open source reference implementation designed to influence standards work on self-sovereign agent technology and self-sovereign identity.


The Patent Privacy Rights Information Governance Label - A proposed standard label for apps and services with access to personal data.
