Definitions

  • the present invention relates to a system and method for providing multiple levels of access to content provided on computer networks and multiple levels of access to computer network communication protocols such as electronic mail (Email) and chat rooms.
  • computer network communication protocols such as electronic mail (Email) and chat rooms.
  • Computer networks such as the Internet or World Wide Web (“Web,” collectively) provide access to immeasurable amounts of content. However, due to age, maturity, religious beliefs, cultural beliefs, personal tastes, and other reasons, all of the available content is not suitable for all of the potential viewers. In addition, computer networks provide the ability to communicate, in a relatively anonymous fashion, using Email or chat rooms. Too often, users receive unsolicited and unwanted communications containing, likewise, objectionable material.
  • Schemes exist that attempt to restrict the types of content or communications received over a given network. However, due to their manner of operation, existing schemes are not foolproof and still allow objectionable material to reach the user. For example, some schemes filter computer network content at the user's computer by blocking access to sites containing keywords or phrases predetermined as objectionable.
  • Filtering schemes are often unsatisfactory because they are both under inclusive and over exclusive. For example, some sites may present objectionable material without the use of a forbidden keyword, thus, including material that should be excluded. In addition, sites may contain a word or words that may have both objectionable and unobjectionable meanings. For example, a site providing content related to carpentry may contain the words “joint” and “butt” in descriptions of various joinery techniques. However, “joint” and “butt” may be on the excluded list due to their frequent use on potentially objectionable sites relating to drug use and pornography respectively. Thus, the filter is over exclusive to the user interested in carpentry joinery techniques. Other drawbacks exist. Other proposed access schemes involve restricting access based upon user identification information.
  • Some operating systems and Web browsers allow the creation of user profiles.
  • the profile contains an indication that the user is of a particular age (e.g., child, teen, adult, etc.).
  • the user profile is transmitted to the server hosting the site.
  • One proposed scheme is for the server to block access to the site if the user profile indicates that the user is not of proper age to view the content as determined by the party hosting or providing the site.
  • One drawback is that the success of this type of restricted access relies on Web site host server compliance and many Web sites may not have an incentive to restrict access to their content (e.g., commercial sites desiring as large an audience as possible). Other drawbacks exist.
  • Another proposed filtering scheme involves limiting access to a certain list of pre-approved sites.
  • a software module is downloaded into the operating system of a user's machine. This module verifies that each uniform resource locator (URL) entered in the Web browser is one that is on the list of pre-approved sites.
  • URL uniform resource locator
  • One problem with this approach is the pre-approved list is at the discretion of the software module provider. Thus, sites that some users do not find objectionable are blocked anyway because the software module provider has restricted access. Also, using a pre-approved site list offers little flexibility to add or delete sites at a later time.
  • Filtering by pre-approval of sites is not always able to prohibit a child from following links off of an approved site out to inappropriate sites. Other drawbacks exist.
  • one object of the invention is to overcome the above and other drawbacks in existing devices.
  • Another object of the invention is to provide a browser that filters Web sites according to a top level domain name. Another object of the invention is to provide a browser that filters content according to computer network address. Another object of the invention is to provide filters to screen email or chat room messages from all but the persons on a predetermined configurable list.
  • Another object of the invention is that a user's site access is not limited by restricted keywords.
  • systems that filter site content using keywords may restrict such important information as is provided in encyclopedias, medical references, or the like.
  • the present invention does not limit site access based on a predetermined list of keywords.
  • the invention provides a computer network browser, capable of accessing Web sites.
  • the particular Web sites that can be access are controlled by the browser.
  • the browser may be configured to only access Web sites containing a certain top level domain name.
  • the browser may be configured to only access Web sites that have a certain type of address.
  • the invention provides a system and method to control the Web sites that a user may access.
  • the system provides filters that restrict the email or chat room messages that a user may receive.
  • the browser (or other email or chat message interface) may be provided with a customizable list of addresses from which a user is willing to accept messages. Any message from an address not on the list will be blocked from reaching the user.

If the parent(s) feel that Web contact with Joan is appropriate, Joan's address may be added to the approved address list by the parent, using the appropriate parental password. In this manner, parents can supervise the addresses (and hence, persons associated with those addresses) from which the child receives messages.

Abstract

La présente invention concerne un explorateur de réseau informatique qui peut accéder à des sites Web. Les sites Web particuliers auxquels on peut accéder sont commandés par l'explorateur. Par exemple, l'explorateur peut être configuré pour n'accéder qu'aux sites Web contenant un nom de domaine d'un niveau supérieur. Dans une autre forme de mise en oeuvre, l'explorateur peut être configuré pour n'accéder qu'aux sites Web ayant un certain type d'adresse. De cette manière, on dispose d'un système et d'un procédé qui permettent de contrôler les sites Web auxquels peut accéder un utilisateur.
