| Almost
everything you do online, whether it's visiting a
website or sending e-mail, leaves a trail of
personal data. Some of it remains on your computer,
some is transmitted to third parties. While this is
not necessarily a bad thing, you can control who
sees it. In the interest of protecting your privacy,
we offer some tips.
E-Mail
Don't mix business and leisure. Get an e-mail
address for personal use.
You have little privacy protection with company
e-mail. Most businesses claim that it is their right
and responsibility to monitor e-mail because it
represents the company, uses company equipment and
travels over the company network. You could argue
the point, but getting a private e-mail address is
much easier. Use your business address for company
business only.
Use encryption
software.
Unless you encrypt your messages--essentially
scrambling the data--your e-mail is no more private
than a postcard. An easy-to-use encryption program
you can download for free is PGP.
Ignore spam.
Sure, junk e-mail is a nuisance, but it's easier to
get rid of than the paper kind--just hit the Delete
key. If you reply to spam, asking to be removed from
the list, it just confirms that your address is
valid. You will soon be spammed and spammed again.
Remove old e-mail
from your computer.
When you delete a message, it's still on your
system. To permanently remove it, open the Deleted
Mail folder, highlight the message and delete it
again.
Be aware that the
message may still reside somewhere on your computer.
A trained technician may be able to recover it.
Messages may also remain on the mail server and be
archived in file back-ups.
Web Surfing
Turn on the cookie alert.
A cookie is a small file sent to your web browser by
a web server to record your activities on a
particular website. To block the cookie, set your
browser to warn you before a cookie is written to
your hard drive, then decide whether to accept or
reject it. Here's how:
If you use Netscape
Navigator 5.0 or a later release, go to the Edit
menu, choose Preferences, then click on Advanced.
Now check this box: "Warn me before accepting a
cookie."
If you use Internet Explorer 5.0 or a later release,
go to the Tools menu, then select Internet Options.
Next, click on the Security tab, then click on the
Custom Level button. Scroll down the list. Under the
Cookie category, check the Prompt option.
Use Anonymizers.
To prevent your activities from being tracked as you
browser websites, use online tools that disguise who
you are and where you come from. One reliable
service we recommend is Anonymizer.com
Review sites'
privacy policies.
Before you provide any information to a site, read
its privacy policy. Every reputable site should post
one. Look for a link on the home page. The policy
should state what information is collected, how it
is used, how it is protected, who has access to it,
and if it is sold or shared with third parties. If
no policy is available, think twice about providing
personal information.
Opt-out.
Websites that collect personal data may allow you to
decide whether the data can be shared with third
parties, such as marketing companies, and whether
you want to receive e-mail offers from them.
Typically you check a box, either agreeing to this
or refusing. You have no obligation to share your
personal information with anyone, so opt-out if the
offer holds no interest.
For more on
opting-out, and an easy way to notify sites that you
want to opt-out, visit the Center for Democracy and
Technology.
Your Computer
Make sure your computer is secure.
If you access the Internet with a dial-up account,
the chances of data theft are minimal. But if you
have high-speed Internet access, such as DSL or a
cable modem, watch out. With these "always
on" connections, you become a more likely
target for hackers. Be sure your computer has a
firewall. Microsoft's XP operating system has one
built-in. But if you need to install a firewall, we
recommend ZoneAlarm. You can download it for free
from ZoneLabs.
Clean up your
history files, location bar list and cache.
As you surf the Web, your browser both records the
addresses of where you have been and stores
downloaded files in a cache. If you want to keep
this information from prying eyes, clear the
temporary Internet files, delete the history files
and the drop-down list under the address or location
bar. While this may seem an extreme step, if you
share a computer, or use a public computer, consider
doing this. Here's how:
If you use Netscape
Navigator 4.0 or a later release, go to the Edit
menu, choose Preferences, then click on Navigator.
Now click on the Clear History and Clear Location
Bar buttons.
Next, To clear the
cache, double-click on Advanced. Now click on Cache.
Finally, click on the Clear Memory Cache and Clear
Disk Cache buttons.
If you use Internet
Explorer 5.0 or a later release, under the Tools
menu, select Internet Options. Now click on the
General tab. Next, click on the Delete Files and
Clear History buttons. |
