Purging or sanitising is the removal of sensitive data from a system or storage device with the intent that the data can not be reconstructed by any known technique. Purging, proportional to the sensitivity of the data, is generally done before releasing media outside of control, such as before discarding old media, or moving media to a computer with different security requirements.

Famous quotes containing the word purging:
“The crime of book purging is that it involves a rejection of the word. For the word is never absolute truth, but only man’s frail and human effort to approach the truth. To reject the word is to reject the human search.”
—Max Lerner (b. 1902)
“The satirical rogue says here that old men have grey beards,
that their faces are wrinkled, their eyes purging thick amber
and plum-tree gum, and that they have a plentiful lack of wit,
together with most weak hams.”
—William Shakespeare (1564–1616)
