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!!

  17. 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.

  38. Federal Trade Commission - Safe Surfing On The Internet - hints for safe traveling on the Internet. • • I can go online —________ (Time of day) for _________ (How long) • It's ___ OK  ___ not OK for me to go online without a parent. • I understand which sites I can visit and which ones are off limits. • I won't give out information about myself or my family without permission from my parents. • My password is my secret. I won't give it to anyone. • 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.

  39. 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. • 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.

  40. 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.

  41. 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.
