Abstract

With the advent of electronic mail systems, there has been an abundance in fields by which a recipient's identity may be defined. Authorizing Users and Reply To Users are just a sample of the number of fields in which a recipient's identity can appear. Periodically, an originator may wish to designate certain individuals as Blind Copy recipients. This term implies that other recipients are not to be disclosed to that the Blind Copy recipient has received the distribution. However, if the Blind Copy recipient's identity unintentionally appears in any attribute of the distribution, then other recipients can surmise that the Blind Copy recipient has received the distribution.

Methodology for Disclosing Blind Copy Recipients to an Originator

       With the advent of electronic mail systems, there has
been an abundance in fields by which a recipient's identity may be
defined.  Authorizing Users and Reply To Users are just a sample of
the number of fields in which a recipient's identity can appear.
Periodically, an originator may wish to designate certain individuals
as Blind Copy recipients.  This term implies that other recipients
are not to be disclosed to that the Blind Copy recipient has received
the distribution.  However, if the Blind Copy recipient's identity
unintentionally appears in any attribute of the distribution, then
other recipients can surmise that the Blind Copy recipient has
received the distribution.

      Furthermore, this problem is compounded in that the Blind Copy
recipient's name may be referenced indirectly either as a nickname or
within a distribution list.  In such cases, the identity of the Blind
Copy recipient may be unintentionally exposed to the other recipients
of the distribution.  A method is needed to ensure that a Blind Copy
recipient's identity is not exposed to other recipients when
nicknames and distribution lists and other forms of indirect
addressing are utilized.

      This article describes a mechanism for detecting the exposure
of Blind Copy recipients to other recipients of a distribution.
Moreover, this method allows an originator to override attributes
which divulge the identities of blind copy recipients.

      Upon a send request with designated Blind Copy recipients, a
service is invoked.  This service scans the recipient lis...
