Abstract
Methods and apparatus for safe processing of on-demand delete requests are disclosed. An item is stored in a storage entity that is associated with a trusted secure device. A delete request to delete the item is received at the trusted secure device. However, the trusted secure device does not yet delete the item from the storage entity. The trusted secure device creates an audit log of the delete request. The audit log specifies the item to be deleted and includes information about the delete request. The audit log is made available to an approval source. The approval source must grant approval in the form of an approval response in order for the item to be deleted. If the trusted secure device receives an approval response from the approval source, the item is deleted.
