Self-destruction - the act of destroying yourself; "his insistence was pure self-destruction". destruction, devastation - the termination of something by causing so much damage to it that it cannot be repaired or no longer exists.
Self destroying LUN
A data handling system having a physical storage device and a storage controller responsible for provisioning, managing, and servicing logical unit numbers (LUNs) with self-destruction properties on the physical storage device is disclosed. For a given LUN, the storage controller creates a profile including self-destruction properties, such as a LUN destruction date, and associates the profile with the LUN. The profiles may be independent of file format and content of any associated data and the LUN destruction date may be a function of the last access date of the associated data. The storage controller monitors the LUN destruction date associated with each LUN and determines the last access date of any associated data. The storage controller marks a LUN having a past-due LUN destruction date, notifies a user of an approaching LUN destruction date, and destroys any past-due LUNs.

A self-destruction document or e-mail massaging system is provided that automatically destroys documents or e-mail messages at a predetermined time by attaching a “virus” to the document or e-mail message. A virus in the form of a Trojan horse is attached to file (such as an e-mail message or document) when it is created. The virus contains a portion of executable code or an executable program which instructs the computer to overwrite and / or delete the file to which the virus is attached at a desired time. Since the virus is attached to the file, it will travel with the file even when the file is copied, forwarded, or saved to disks or tape drives.
