Abstract
A security paper shredder where the residue of individual shredded document pages are collected in multiple collection bins for disposal, ensuring that no single collection bin contains the residue of any entire page. To further ensure that no adversary could obtain the contents of all the multiple collection bins and reassemble the document, the contents of the collection bins are disposed of at differing times and in geographically dispersed locations.
