Abstract

The authentication certificates of the certificate registry are associated in a manner at least partially dependent upon at least one of a particular type of information that the information providers provide, a particular organization that the information providers are associated with, a particular type profession in which the information providers are engaged and a particular geographical region in which the information providers are located.
