Email
The most common way of snooping is people
getting access to your computer.
Be sure to always sign off and close the kerberose
ticket.
Some email programs like Netscape and Outlook
keep copies of your email on your computer even
after you have logged of the email system
• You would need to leave a copy on the server and delete
the downloaded one.
Browsing
World Wide Web Site
Unregulated
Un-Moderated
From Very Useful ->Mis-leading, Violent and
Pornographic
Often the First Step to More Interactive
Experiences
Cache Files in the System Folder Hold a
Copy of the Most Recent Pages and Images
What All WWW Sites You Visit
Know About You
What browser you are using
What Operating System is on your computer
(Mac, Windows ‘98 etc)
What page referred you to that site
The IP address of your computer (What
domain or company you are coming from)
Free ISP services track even more
information about you and have rights to
resell that information
Sites can build a profile of your
visit that includes:
Which pages you visited
How long you stayed there
Where you went from that site
Cookies
Sites can put a piece of information on your
computer
Normally a unique ID for you on their site.
Mostly used for return visits in order to
identify you and track your browsing patterns
and interests.
Amazon.com uses cookies to make book
recommendations when you return to their
site
Yahoo will present you with your favorite
news or stock information
More Cookies
Some sites allow a separate company to
deliver cookies to your computer
These “Profilers” build comprehensive profile
of your surfing habits in order to place
individual adds that target your interests on
partners sites.
The profiler “Double-Click” just bought a
direct mail database (Abacus Direct) in order
to merge your other buying habits with your
web profile.
They now have access to billions of transactions
at stores such as Bloomindales
Surf Anonymously
Some sites (Anonymizer.com) can use
its server to mask your ID
They have a free service that delays your
surfing some
They have a faster “premium service” for
$5 /month
Control Your Cookies
Some Sites allow you to “Opt-Out”
Takes time to do this
Voluntary and not required
Center for Democracy & Technology (COT)
has a site to assist
Opt-out.cdt.org/online
Newer versions of Netscape and Explorer
allow you to turn off cookies
Can be limiting - some sites require cookies.
Internet Explorer’s Cookie
Controls
Be careful with Personal
Information
Placing your child's name, picture, address, school,
phone number, or other information on the Internet
means that anyone visiting the site could easily
identify your child and possibly locate them
Key information like address, DOB, place of birth,
mother’s maiden name and SSN can be used to steal
identities and apply for credit cards in your name.
With enough information to uniquely identify a person,
their SSN can be purchased on line for about $25.
If you suspect a stolen ID -> Move Fast!!
Federal Trade Commission
Privacy Guidelines for Children
Here are some important things to know about surfing, privacy and your personal information:
Never give out your last or family name, your home address or your phone number in chat
rooms, on bulletin boards, or to online pen-pals.
Don’t tell other kids your screen name, user ID or password.
Look at a website’s Privacy Policy to see how the site uses the information you give them.
Surf the Internet with your parents. If they aren’t available, talk to them about the sites you’re
visiting.
Talk about the site’s Privacy Policy with your parents so that you and your parents will know
what information the site collects about you and what it does with the information.
Websites must get your parent’s permission before they collect many kinds of information from
you.
If a website has information about you that you and your parents don’t want it to have, your
parents can ask to see the information – and they can ask the website to delete or erase the
information.
Sites are not supposed to collect more information than they need about you for the activity you
want to participate in. You should be able to participate in many activities online without having
to give any information about yourself.
If a site makes you uncomfortable or asks for more information than you want to share, leave the
site.

More Chat
Chat also gives you the option of ignoring specific chatters, as well as
using a language filterMost chat areas have clearly stated rules and
guidelines for what is appropriate; failure to follow the rules may result
in negative responses from other users and, ultimately, a loss of
privileges.
Clubs allow people with similar interests to interact in focused online
forums. Club members have the ability to post messages, take part in
chats, send email messages to one another, and even post pictures.
Clubs has an established set of rules that users must follow.
Message boards generally list the username of the person who posts
a message. Therefore, we encourage you to create an alias for your
child so that their true name is not visible on any posted message

I will never agree to meet an online pal, or send my picture, without
permission from my parents.
I know an advertisement when I see one. I also know that animated or
cartoon characters aren't real and may be trying to sell me something
or to get information from me.
I will follow these same rules when I am at home, in school, or at the
library or a friend's.
FBI's Safety Tips for Kids on the Internet
safety tips from the Federal Bureau of Investigations which all kids should know and follow
while online. www.fbi.gov/kids/crimepre/internet/internet.htm
Never give out identifying information such as Name, Home Address, School Name, or
Telephone Number in a public message such as at a chat room or on bulletin boards. Never
send a person a picture of you without first checking with your parent or guardian.
Never respond to messages or bulletin board items that are:
*
Suggestive, Obscene, Belligerent, Threatening, Make You Feel Uncomfortable
Be careful when someone offers you something for nothing, such as gifts and money. Be
very careful about any offers that involve your coming to a meeting or having someone visit
your house.
Tell your parent or guardian right away if you come across any information that makes you
feel uncomfortable.
Never arrange a face to face meeting without telling your parent or guardian. If your parent or
guardian agree to the meeting, make sure that you meet in a public place and have a parent
or guardian with you.
Remember that people online may not be who they seem. Because you can't see or even
hear the person it would be easy for someone to misrepresent him- or herself. Thus,
someone indicating that "she" is a "12-year-old-girl" could in reality be an older man.
Be sure that you are dealing with someone that you and your parents know and trust before
giving out any personal information about yourself via E-mail.
Get to know your "online friends" just as you get to know all of your other friends.
Yahooligan’s Rules
*
Time online: Discuss how much time they are allowed to spend online, and
whether their computer use is dependent on conditions such as finishing their
homework, doing chores, etc.
*
Location/Supervision: Decide whether there are restrictions or guidelines on
the physical location where the kids can go online. Can they go online at school? In
the library? At a friend's house? Are they allowed to be online when no adult is
around?
*
Personal information: Kids should never give out personal information, such
as their full name, address, phone number, school, or picture, to anyone they meet
online.
*
Web sites: Talk about which kinds of web sites are okay, and which ones are
off-limits. Are they limited to sites related to their schoolwork? Sites that are designed
especially for kids? Only sites that are listed in the Yahooligans! directory?
*
Meeting online friends: Kids should never arrange to meet an online friend in
person without an adult present.
*
Chat rooms: Explore a few chat rooms together while discussing your
guidelines. What is your comfort level with this method of communication? Do you
want your children to chat in monitored chat rooms only? Are your children allowed to
send personal messages to people they've only met online? Check out the "Chat"
category on Yahooligans! for an up-to-date listing of links to moderated chats for kids.
More Yahooligan’s Rules
*
Inappropriate material: Kids should never respond online when they feel
uncomfortable or scared by something they've seen or read. If they have any doubts, they
should find an adult immediately and show them the inappropriate material.
*
The Golden Rule: Remind your kids to behave towards other kids as they would like
people to behave towards them. Something that could hurt another child's feelings on the
playground will still hurt when received by email or in a public chat.
*
Web sites: Remind your child of the use of the "back" button. If they come upon a site
that isn't what they'd expected, he/she should click "back" immediately and then come tell
you what happened. If a web site is misrepresenting itself, complain to the creator of the site.
*
Email: If your child receives an email message from an unfamiliar address, they
shouldn't read it and should tell you about it. If it's something inappropriate and unsolicited,
request of the message's source that they delete your child's email address from their
database. If this becomes an ongoing problem, complain to your Internet service provider.
*
Chat Rooms: We strongly recommend that you actively monitor your children while
they participate in online chats (more so than any other online activity). Yahoo! Chat users
have the ability to Ignore specific chatters, which helps to prevent any one chatter from
becoming an ongoing problem for your child. Additionally, you can control the language your
child sees with the Language Filter.
