Patent attributes
An authentication server can receive an electronic message transmitted by a sender. The electronic message can have an intended recipient and can include message data. A sender identification (“ID”) is embedded in the message data. The authentication server can generate a first message ID based on the message data that includes the sender ID. The first message ID can be determined to match a second message ID that is stored in a database. The sender ID can be determined to be different from an originator ID that is associated with the second message ID in the database. The authentication server can determine whether an originator associated with the originator ID has authorized the sender to transmit the message data and can determine whether to transmit the electronic message to the intended recipient based on whether the originator has authorized the sender to transmit the data.
