SECURING SELECTED DATA WITHIN A MESSAGE

Methods, systems, and data structures are provided for selectively securing data within a message. A single message includes data. The data can be text data, attachment data, audio data, image data, or video data. Portions of the data are selectively identified with intended recipients. Multiple versions of the message are produced using the selective portions of the data. Each appropriate version of the message is delivered to the intended recipients. In one embodiment, the selective portions of the data are presented as links in the versions of the message, such that when an intended recipient accesses the link, the accessing recipient is first authenticated before being granted access to the selective portions of the data.
