Abstract: Techniques are provided for generating and managing temporary email addresses. A requestor having a requestor email address makes a request to receive a temporary email address. The temporary email address is generated and mapped to the requestor email address. Messages received that are associated with the temporary email address are mapped to the requestor email address and forwarded to the requestor. The temporary email address expires when an expiring event is detected.

Abstract: 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.
