An internet filter is a hardware or software solution that prevents access to some undesirable areas of the internet. An internet filter can work by various methods. Some compare site requests with a list of previously known bad URLs and preventing viewing if they are listed, others by scanning incoming data and blocking it if it contains unwanted keywords or file types.
An internet filter is not 100 percent effective. An unwanted site may appear to the user. The filter may skip over bad keywords when filtering causing an unwanted site to appear on the user’s computer. Sometimes the parent can control or create the list of keywords or sites filtered but sometimes not.
