Abstract

Described is a methodology for preventing receipt of duplicate copies of distributions. It is desirable in many environments to prevent a duplicate copy of media or distributions from being received by recipients. Many times a distribution, such as electronic mail, fax images, voice messages, etc., is sent to recipients who, in turn, send, forward or resend the distribution to other recipients, again who may, in turn, send, forward or resend to other recipients. Unfortunately, the same distribution may be sent more than once to the same recipient from different sources. A mechanism is required to prevent duplicate media from being received by the same recipient.

Distribution Duplication Prevention Mechanism

      Described is a methodology for preventing receipt of duplicate
copies of distributions.  It is desirable in many environments to
prevent a duplicate copy of media or distributions from being
received by recipients.  Many times a distribution, such as
electronic mail, fax images, voice messages, etc., is sent to
recipients who, in turn, send, forward or resend the distribution to
other recipients, again who may, in turn, send, forward or resend to
other recipients.  Unfortunately, the same distribution may be sent
more than once to the same recipient from different sources.  A
mechanism is required to prevent duplicate media from being received
by the same recipient.

      This article describes preventing the same arbitrary media
distribution from being received by the same recipient.
Distributions are accompanied with attribute information which can be
used to determine whether or not a distribution is identical to
another.  Attributes which can be used are media type, creation
date/time stamp, submission and/or time sent date/time stamp, unique
delivery identifier(s), distribution size, etc.  Depending on the
media, a collection of attributes is used to assess equivalence
between a distribution received and existing filed or accounted
distributions.  This method compares attributes of incoming
distributions with existing filed or pending distributions to
determine whether or not the incoming item has alre...
