Call me obsessive, but I need to return to the subject of paper security.
It seems to me that if an organisation insists on printing out documents, it should do so only on rice paper. Using flavoured, organic ink (perhaps even containing vitamin supplements) would turn unwanted printouts into a company-wide source of low-cost snack food. Only a little imagination is needed to imagine adding milk and making a form of rice pudding.
It would certainly save on the costs of commercial shredding services and reverse digestion is never going to be a practical approach -even for the most ardent data thieves.
