By: Claire Sherrington

sets so large and complex that it
becomes difficult to process
using on-hand database
management tools or traditional
data processing applications.

So why should I care?
“Big Data is really about new
uses and new sights, not much
about the data itself” says Rod A
Smith (IBM)
Big data: the greater good or invasion
of privacy?
“There’s no bad data, only bad
uses of data,” says Craig
Mundie, a senior adviser at
Microsoft,
What can do I ?
Remember that YOU decide what information
about yourself to reveal, when, why, and to
whom.
Be conscious of Web security.
Keep a "clean" e-mail address.
Realize you may be monitored at work, avoid
sending highly personal e-mail to mailing lists,
and keep sensitive files on your home computer.
