`(57)
`A web browser system has a network
`that connects a user
`computer having a local database with local database entries
`therein with a central database having central database
`entries therein. A web browser has a domain name entry area
`to the website. A
`for entering a domain name corresponding
`to a plurality of
`controller
`compares
`the domain name
`database entries within a local database. When the domain
`is not
`is
`local database,
`the domain name
`in the
`name
`to a plurality of central database entries
`compared
`in a
`the network. When
`central database
`the domain
`through
`name is in the local database or central database, access to
`is
`the website is enabled. In addition
`to the system, parsing

`
`WEB BROWSER FOR LIMITING ACCESS TO
`CONTENT ON THE INTERNET
`
`RELATED APPLICATION
`[0001] The present invention claims priority to provisional
`application No. 60/232, 330 filed on Sep. 13, 2001.
`
`TECHNICAL FIELD
`
`[0002] The present invention
`relates generally
`to an appa-
`ratus and method for limiting access to content on a network,
`for
`to an apparatus
`and more particularly,
`and method
`access
`to content on
`or allowing
`Internet
`the
`limiting
`deemed unsuitable or suitable by an administrator.
`
`BACKGROUND OF THE INVENTION
`[0003] As the proliferation of the Internet
`increases,
`the
`variety of types of content also increases. Children
`in their
`studies now require access to the Internet to perform various
`tasks. Some content on the Internet, however, may not be
`suitable for children of various ages.
`
`[0004] To restrict access to websites, various systems are
`known. One system for restricting access uses a key that is
`to a user upon age verification. The drawback
`to
`provided
`such a system is that not all websites that include unsuitable
`content require a key for access. Therefore, access to these
`systems may be undesirably
`allowed.
`[0005] Web browsing systems are also known
`that store a
`list of disapproved websites on the user's computer. If the
`to be accessed is on the disapproved
`website sought
`list,
`access is denied. One drawback
`to such a system
`is that
`the access
`Internet content providers
`continually
`change
`addresses and new sites are constantly being added. There-
`fore, such lists become outdated nearly as fast as they are
`to such a system is that the lists
`created. Another drawback
`to adult oriented websites. Unfortu-
`restricted
`are typically
`nately, well-known websites may have content
`that is not
`age appropriate. Such systems do not distinguish
`the age
`appropriateness of such content and therefore either denies
`access to all content or allows access to such content even
`the content is not appropriate
`for the user.
`though
`[0006] Another practice on the Internet
`includes redirect-
`ing users who enter a first website address and are auto-
`to another website with another address.
`matically
`rerouted
`the redirection of the user
`Known systems cannot prevent
`and therefore a redirected user may end up at a site with
`content.
`inappropriate
`[0007]
`It would
`to provide a web
`therefore be desirable
`access to
`that allows age appropriate
`browsing
`system
`approved sites while preventing access of users to inappro-
`priate websites.
`
`SUMMARY OF THE INVENTION
`
`[000II] The present
`provides
`invention
`improved
`an
`that connects a user
`browser system that includes a network
`computer having a local database with local database entries
`central database
`therein with a central database having
`entries therein. A web browser has a domain name entry area
`to the website. A
`for entering a domain name corresponding
`to a plurality of
`controller
`compares
`the domain name
`database entries within a local database. When the domain
`is
`local database,
`is not
`the domain name
`name
`in the
`
`to a plurality of central database entries
`compared
`in a
`the network. When
`central database
`the domain
`through
`name is in the local database or central database, access to
`is enabled.
`the website
`
`a method for
`
`[0009]
`In a further aspect of the invention
`accessing a web page comprises:
`[0010] entering a domain name corresponding
`site;
`[0011] comparing
`the domain name to a plurality of local
`database entries, local database having a plurality of local
`database entries;
`
`to a web-
`
`[0012] when the domain name is not in the local database,
`to a plurality of central data-
`the domain name
`comparing
`base entries
`in a central database;
`[0013] when
`the domain name is in the local database or
`central database, enabling access to the website.
`[0014] In a further aspect of the invention,
`a website comprising:
`sponsoring
`[0015] generating
`subject buttons;
`[0016] selecting and actuating a first subject button from
`said plurality of subject buttons;
`[0017] displaying a question and a plurality of answers
`to the step of selecting;
`response
`
`a method of
`
`a screen display having a plurality of
`
`in
`
`[001II] displaying
`[0019] selecting
`answers;
`
`a first sponsor code on said display;
`the plurality of
`
`a first answer
`
`from
`
`[0020] displaying
`a narrative display
`step of selecting a first answer.
`
`in response
`
`to the
`
`[0021] In yet another aspect of the invention, a method for
`parsing a domain name entry comprises:
`[0022] entering a full domain name having a plurality of
`character positions;
`
`the full domain name;
`
`[0023] capturing
`[0024] capturing a first domain name by capturing char-
`acters right of a first symbol and left of a second symbol to
`obtain a first name.
`
`[0025] Yet another aspect of the invention
`includes updat-
`information on a website and browser;
`ing advertising
`
`[0026] providing a local computer ad code having a first
`plurality of bits and a central computer ad code and a second
`plurality of bits;
`
`[0027] comparing
`the local computer
`central computer ad code;
`
`ad code with
`
`the
`
`[002II] when the local computer ad code is not equal to the
`an ad to the local
`central computer ad code, downloading
`from the central computer.

`[0029] One advantage of the invention
`is that the system
`to access to various

`72, various
`start up pages may also be associated with
`various age levels. For example, grades 2 and under may
`have a first page, grades 3 through 7 a second page, and
`grades II through 12 a third page. For a business application,
`various levels of employees may also have access to various
`content on the Internet. For example, system administrators
`may have complete access to the Internet while mailroom
`clerks may have access to the company's website through an
`Intranet.
`
`[0059] After step 72, step 74 determines whether a new
`version of the browser software
`is available. This step may
`be performed by accessing central computer
`the

`In step 74, if a new version is not available and in

`[0062] Referring now to FIG. 4, the navigation process is
`in step 94. The navigation
`initiated by some user interaction
`in URL
`process is initiated by a user typing
`in (for example
`display 42 of FIG. 2) or selecting a desired URL (Uniform
`Resource Locater). Before navigation can begin, a parsing
`to determine whether or not permission
`process is performed
`has been granted for the site for the particular security level.
`In step 96, the entire entered URL is captured and a hidden
`is opened
`browser
`in step 9II so that redirection
`technique
`may be uncovered. The hidden browser is hidden from view
`and therefore not accessible to an end user. The URL is then
`checked for hidden
`in hidden browser
`redirection
`in step
`100. If in step 100 a redirection has been performed or not
`in step 102. It should be
`performed, a final URL is returned
`noted that the parsing process does not wait for the complete
`page to be downloaded. The parsing process requires
`the
`final destination of the HTML document. After the HTML
`text is loaded the parsing process stops the navigation of the
`hidden web browser object and thus stops the loop.

`returned URL in step 102 may,
`for example, be
`final
`http: //maps. yoohoo. corn/index. html. If this is the case, one
`or more names may be returned by the parsing process. The
`pointer of the parsing program starts at the left and looks for
`the first colon in step 104. After the colon, the pointer moves
`two places to the right in step 106. Two places were chosen
`to avoid the two slashes. The desired name is then captured.
`the second place and the first slash is
`Everything between

`[0064] After step 10II, step 110 is executed
`in which

`second period is not present, step 112 is executed in which
`a period is added to the beginning of the name. If a second
`in step 110, step 114 is executed. Step 114
`period is present
`is also executed after step 112. In step 114, the characters
`to
`the left of the first period are disregarded.
`In the present
`example, ". yoohoo. corn" is captured as name2. By allowing
`from a single URL, a portion of

`central or remote database is searched for name1. After step
`132, step 134 is executed in which if name1 was not found,
`step 136 is executed. In step 136, name1 is submitted
`to the
`approval screening system 34 of FIG. 1.

`in which
`the
`user's security level is determined whether or not it satisfies

`is
`the particular
`level and the level
`made between a database entry indicating

`[0072] When X=1 this indicates that the domain name was
`found and is approved. Therefore, the user's security will be
`
`checked as in step 14II. If the user's security level is less than
`the approved domain's
`level, a message will be
