MULTIMEDIA MESSAGING SERVICE (MMS) ORIGINATOR AUTHENTICATION

摘要

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.

主权项

1. A method comprising:
receiving, by a processor associated with a multimedia messaging service (MMS) center (MMSC), an MMS message associated with forwarding multimedia content to a recipient device, wherein the multimedia content is associated with an identifier for a source device, the MMS message includes tagging data, and the tagging data is generated based on a numerical key and an identifier for a sending device that transmits the MMS message; parsing, by the processor, the MMS message to determine the identifier for the source device and the tagging data; obtaining, by the processor, the identifier for the sending device using the tagging data; determining, by the processor, whether the source device corresponds to the sending device; processing, by the processor and when the source device corresponds to the sending device, the MMS message to enable the recipient device to access the multimedia content; and discarding, by the processor, the MMS message when the source device and the sending device differ.
