Planning to spring clean your home or office? One of the biggest parts of spring cleaning is getting rid of clutter you no longer need. In the past, this meant tossing junk like a broken typewriter or planning a garage sale to recoup a few bucks for an old television. But in today's digital age, the adage "when in doubt, toss it out" could actually put you in harm's way. Identity thieves make a career seeking out discarded sensitive documents or digital devices loaded with personal data.
Whether an unwanted digital device or document is headed for the trash, a garage sale, storage, or Goodwill, here are some helpful tips to keep your data safe:
toss documents - Shred or incinerate them. The saying "one
person's trash is another person's treasure" rings especially true for
identity thieves. Fraudsters look for any documents containing Social Security
numbers, financial account numbers, your driver's license number, and health
insurance account information. Savvy criminals will dig through your trash,
hunting for data that can be used to steal your identity. Always use a
cross-cut, diamond-cut, or confetti-cut shredder. Unlike strip-cut models in
which the pieces can potentially be put back together, these shredders will
produce much smaller pieces.
a shredding facility. If
you have a large amount of shredding and are not able to handle it at home,
consider taking it to a shredding facility that guarantees and certifies that
your documents are fully destroyed. If you have a large amount of papers to
destroy (this can occur, for example, when an elderly family member passes and
the family must dispose of decades of documents), there are services that will
send a shredding truck to your home. Fees are charged for both types of
sensitive documents under lock and key. "Old fashioned" physical security still has a
place by discouraging opportunistic thieves. Centralize sensitive paperwork and
invest in a locked filing cabinet. Or you can simply take advantage of a
locking desk drawer. Another option is to scan such documents and save them
destroy old flash drives.
Flash drives are different than hard drives. A 2010 study by the University of
California, San Diego
found that applying hard drive data sanitization methods to flash drives was
unreliable. Open the drive and smash the circuit board and chips. Read Campus

old computer hard drives. Often,
computer files continue to exist on the hard drive, even after you've deleted
them using keyboard and mouse commands. Use specialized software such as Eraser to remove specific files. To delete an entire hard drive’s
data, use software like Darik’s Boot and Nuke.
Before recycling or selling your old computer, make sure you've successfully destroyed all personal data. You may be better off physically destroying the hard drive and taking the computer and destroyed drive to an electronics recycling center. For more details, read Popular Mechanics: How to Absolutely, Positively Destroy Your Data.
Do not toss any digital devices into your trash bin, and don't take them to the municipal waste center. By taking both intact and destroyed digital devices to an electronics recycling center, you are ensuring proper disposal regarding both your privacy and environmental protection.
data from cell phones. Cell
phones are like computers in that deleting data using the user menus may not
truly delete it from the hardware. Always wipe your phone by deleting the data using menu settings and
then performing a factory reset. Every phone has a different process, so check
the phone's manual to restore the phone to its factory settings, or search
YouTube for an instructional video. According
to PCWorld, no wipe solution is perfect. The only way to totally guarantee old
cell phone data is gone for good is to take the phone apart and physically
destroy the memory chip.
If you're wondering what to do with your wiped phone, we recommend donating it to a nonprofit that provides used cell phones to soldiers, domestic violence victims, and others. Unless the phone is truly a relic, there are many who would appreciate the donation.
the hard drive on unwanted digital copiers. Nearly every digital photocopier since 2002 contains a hard
drive. The hard drive stores an image of each document processed by the
machine. Check your machine's manual for instructions on how to clear the data
from the hard drive before getting rid of the copier.
and DVDs should be physically destroyed by breaking them into many pieces. A pair of Wiss Tin Snips (scissors that can cut through tougher materials) will help you easily cut your CDs and DVDs into four or more pieces. Some shredders can do this, too. If you are
destroying older media, such as floppy disks and tapes, remove the film and cut
it into small pieces.
- Know the law when disposing of business documents. If you work from home or operate a small business out of your home, data destruction should be especially rigorous. There may even be industry standards and federal and state laws that you must comply with regarding proper disposal of business-related documents. As a small business, you certainly don't want the negative publicity that comes with having to notify individuals of a data breach, the law in 46 states.
Spring cleaning should lead to a more organized home and office, not make you the victim of identity theft. We hope these tips will help you keep your personal data safe.
