Abstract
A system, computer program product and method of preventing recordation of true keyboard acoustic emanations are provided. In an embodiment, it is determined whether a user has stricken a key on a keyboard. In response to the stricken key a keystroke sound from a mask which is dissimilar to a keystroke sound produced by the stricken key is emitted to drown out the keystroke sound of the stricken key. In another embodiment, when a plurality of keys is stricken, a random keystroke sound is emitted between keystroke sounds made by two stricken keys to blur out word boundaries.
