Abstract

As the Web is increasingly used as a user interface and transport for many different types of applications, there will be an increasing need to limit the types of information that users are allowed to access. This feature will be used to protect scarce RF resources, prevent access to questionable or sensitive material, and reduce unproductive surfing. Web filters are a well known approach to limiting a user's ability to access to certain Web sites or Web sites with particular key words or URL patterns. However, Web filters are based on static rules and do not accommodate a dynamic situation. Given the expectation that users will operate in a mobile and quickly evolving environment, a need exists to limit Web access based on factors such as each user's individualized context, access technology, and terminal type.

User Constrained Browsing

By Donald G. Newberg and Matthew C. Keller

As the Web is increasingly used as a user interface and transport for many different types of applications, there will be an increasing need to limit the types of information that users are allowed to access.  This feature will be used to protect scarce RF resources, prevent access to questionable or sensitive material, and reduce unproductive surfing.

Web filters are a well known approach to limiting a user’s ability to access to certain Web sites or Web sites with particular key words or URL patterns.  However, Web filters are based on static rules and do not accommodate a dynamic situation.  Given the expectation that users will operate in a mobile and quickly evolving environment, a need exists to limit Web access based on factors such as each user’s individualized context, access technology, and terminal type.

It is expected that future communication systems will require a sophisticated attribute database of user, terminal, and system attributes to provide a rich set of call processing features based on context.  A mechanism is proposed that utilizes this attribute database information, which will already exist for the communication system, to constrain a particular user's ability to access Web sites. 

The following system diagram shows a communication system made up of a radio systems core, user terminal, and the attribute database containing information about the user’s identity, preferences, group affiliation, context (emergency, off duty), etc.  The attribute database is an integral part of the communication system and is populated via normal activity (shown by dotted lines indicating user registrations, terminal registrations, group affiliations, and system administration).  It is shown as a single entity for convenience, although in practice it would most likely be made up of a number of distinct and distributed databases.

The proposed invention adds a “Web filter” device that intercepts and processes all Web requests and responses.  It provides a method to constrain a particular user’s access...
