Abstract
A multimedia messaging service (MMS) center (MMSC) receives an MMS message associated with forwarding multimedia content, associated with a source device, to a recipient device. The multimedia content is tagged with tagging data that is generated based on a numerical key. The MMSC parses the modified MMS message to determine the source device and the tagging data. MMSC uses the tagging data to determine the sending device using the tagging data. For example, the MMSC may access an identifier for the sending device, as stored by a subscriber profile controller, using the tagging data and/or a Lightweight Directory Access Protocol (LDAP) interface. The MMSC determines whether the source device associated with the MMS message corresponds to the sending device (e.g., whether the MMS message correctly identifies the sending device), and the MMSC discards the MMS message when the source device and the sending device differ.
