There are always the aspects of risk with any public registry or repository, but protecting information is instrumental by isolating those who have access to it and providing the right security credentials around it. It is an aspect of build, of any new form of technology, and security can be incorporated into those measures.
The real question to ask, as well, is to what degree is the information sensitive and needs to be protected. There is some information that might be beneficial to have publicly available in this regard and that consideration needs to be undertaken as well. I think there are aspects of public registries in other jurisdictions that have both public and private aspects.
As a banking institution, we use public registries today or private registries through the correspondent banking network, and it has been quite useful to banks to use that.
