Data on paper is the same as data on the screen.

Sometimes it's necessary to print out copies of important or sensitive data. If you have sensitive printouts, don't leave them lying around where unauthorized, prying eyes can see them. The data is just as sensitive and confidential on a printed page as it is on a computer screen, and if you don't want it read on the monitor, you probably don't want it read anywhere else. Keep important printouts in a secure location, and when you don't need them anymore, don't just throw them in the waste basket - shred them. Personal shredders ("cross-cut" preferred over "strip") are inexpensive and very useful in not only disposing of confidential printouts, but also junk mail, credit card offers and other printed material that may contain information about you that could be useful to identity thieves.
