Abstract
A data deletion system and method detects data deletion notification data representing a desire to delete data, such as a data delete command from a storage management system such as an operating system or other software application. The system and method provides a system invoked deletion process that modifies the desired data to be deleted in response to the detected data deletion notification data. The system does not require continued user invocation to select data to be deleted. Modification of the desired data to be deleted includes actual deletion of the information by overwriting the desired data to be deleted with random data or other process such as overwriting original data multiple times, to ensure that there is no detectable electronic signature of the original data.
