Assurance
+
Assurance is the process by which a Member of CAcert Community (Assurer) identifies an individual (Assuree). +
+With sufficient assurances, a Member may (a) issue certificates with their Names included, (b) participate in assuring others, and (c) other related activities. The strength of these activities is based on the strength of the assurance. +
+
Member
+
An individual who has agreed to the CAcert Community agreement and has created successfully a CAcert (web)account on http://www.cacert.org. +
Name
+
A Name is the full name (first name(s), family name(s), name extensions,abreviation of name(s), etc.) of an individual. The Name is technically spoken a string exactly taken from a governemental issued photo ID. Transliteration of characters to a character table defined by CAcert is permitted. +
+
Secundary Distinguished Feature (DoB)
+
A Name for an individual is discrimated from similar full names by a secondary distinguished feature, as recorded on the on-line CAcert (web) account. +Currently this is the date of birth (DoB) of the individual. +
