Parents should use caution when allowing children to communicate with others using sites such as Skype or Oovoo. No service that allows children to communicate with people on the Internet can be considered completely safe.
With close parental supervision and proper use of privacy settings, services like Skype and Oovoo are quite safe. However, unscrupulous users could gain information about someone who has permission to chat with a child and impersonate them. Setting up a password or keyword before chatting is another good way to verify the identity of people on the Internet. When in doubt, calling the chatter on the telephone or someone who can verify that the chatter is who they claim to be is advised. It is recommended that children under 18 use chat services with their parents' permission using accounts registered in their parents' names.
