For me, every day it becomes more evident the need to validate information managed by the RIRs / NIRs / LIRs on separate information platforms.

A very simple example is PeeringDB itself, which requires confirmation of correlation between the ASN whois contact and the account that is registering the organization.

P.S.1: At least for me, this is more evident when it comes to numerical resources, but without going much deeper into the analysis, I believe that this is also applicable to name resources.

I was wondering how complex it would be for RIRs / NIRs to implement some mechanism similar to the OAuth of NIC-Handler accounts to, through a delimitation protocol, allow accounts between information platforms to be correlated, information to be confirmed and maybe even inserted and updated.

Still dreaming a little bit about the possibilities, I imagined that in a federation context, IANA or NRO could correlate NIC-Handlers from the same organization in different RIRs.

In addition to the PeeringDB example, other uses (non-exhaustive list) of this solution could be:
 - Linking between Maintainers of IRR bases and owners of resources in RIRs.
 - Linking between accounts on the basis of IXPs, and ASN owners.
 - Authentication and integration of RPKI CA Delegate services.

I believe that we are already at a point where we can go beyond just using email confirmation.

OAuth and similar protocols include benefits such as:
 - Simplified use of cryptographic protections
 - Specific definition of the duration of the authorization.
 - Forced expiration of authorization.
 - Granular definition of which attributes will have read-only or read and write access.

I know that for a person with little experience everything seems possible, and for more hardened people things do not seem that simple.
I also know that not everything in this world depends only on technological feasibility. For although there may be protocols and techniques to solve a problem, many questions depend on the layer 9 definitions of the OSI model.

P.S.2: To be honest, I don't know if there are already initiatives in this direction from the point of view of making this a standard resource. But unless I am mistaken, https://www.denic.de/ already has something similar in place.
