Internet Filters and Parental Control Software

In today's society, many young children are using the internet in a way that their parents have no idea what they are specifically doing.  There is a way to prevent children from looking up in appropriate things which is not hard to do.  There is a software designed to restrict or control the content of the reader over the internet or email.  Content control software determines what content will be able to be viewed and what content will be blocked.  One way to block information available to minors is by implementing internet filters.  Filters can be implemented by a software on a personal computer or firewalls that provide Internet.

Some types of filters are the following:  e-mail filters, content-limited, and search-engine filters.  E-mail filters can control what information is being sent out in the body, the header, and even who the e-mail is being sent to.  If the person receiving the e-mail has this type of filter, the e-mail server will check the information that is being received and if it is inappropriate the email will be rejected.  Content-limited filters are Internet service providers that only allow access to a certain amount of information.  The search-engine filter can be used by parents to prevent their children from searching all forms of inappropriate information.  If a website features inappropriate, explicit, or adult information the children will not be able to preview it.  Instead, a webpage will show that access has been denied.
