UMPINT was created by RowIT Ltd. We an IT consultancy based in London, UK.
We created this service as felt the need for authentication documents was huge, and nobody seemed to be offering a cheap and simple solution. What we have provided is a trustless solution - meaning you don't need to trust us - that allows anyone who issues electronic documents to sign them for virtually zero cost.
We are in the process of getting an official legal opinion about the use of our certificates in court. Once we have this we will post on our website.
We are also undergoing an independant security review. Once we have completed this we will post the report up on our website.
