The Trinity product is split into two parts; the Trinity backend services and the Trinity SDK. They enable the implementation of an OpenID connect service provider while respecting Self-sovereign identity principles in a novel (patent pending) privacy and user consent preserving process, while limiting the profiling possibilites of the operator and catapulting user data protection to a whole new level. It can be used to build modern single-sign on applications to initiate data verification, authentication and trust in the user on the highest level. The protocol behind the product integrates modern cryptographic techniques to guarantee data integrity and encryption between the user and client applications end-to-end.
