Request: Demonstration of Support for Selective Disclosure for Data Integrity

Hi all,

I need your help demonstrating support for a NIST-compliant selective
disclosure mechanism for Data Integrity in the Verifiable Credentials
Working Group. You might want this technology if you plan to issue a
Verifiable Credential (such as a work permit), but want to empower the
holder to only reveal a subset of that credential (only the document
identifier, full name, and the country where the permit is valid).

The announcement that such a mechanism has been designed and
implemented is here (along with a presentation of the technology):

If you are considering adding your name to the list of supporters,
please remember that:

* It carries more weight if you are adding your organization to the
list AND/OR you are an implementer that plans to implement or
integrate the solution into your technology stack.

* This is ONE of multiple possible selective disclosure mechanisms for
Data Integrity, and is not intended to be the ONLY one. Others, such
as merkle-tree disclosure mechanisms are also possible to deploy in
parallel to the NIST-compliant mechanism described in this email.

* This is NOT a replacement for BBS for Data Integrity, which provides
both selective disclosure and unlinkable signatures (but does not use
NIST approved cryptography). BBS can be deployed in parallel to the
NIST-compliant selective disclosure mechanism.

Please add your name to the list of supporters here:

When you do, please mention if you are a W3C Member, whether you're an
implementer, and whether or not your (or your customers) would benefit
from this technology feature existing. If we get enough signatures, we
will put the proposal in front of the W3C VCWG for consideration.
