Abstract

This publication defines a method for Location Based Privacy using Meta Data and Parameter Driven Dynamic Rules, for applications which use the current location of the wireless device initiating the application request. Privacy is of the essence in Location Based Services. Users need to have control over the who, what, when, where, and how their location is shared. This method exploits the use of Meta Data and a Parameter Driver Dynamic Rules Based System to provide a privacy solution for location-based services. In this invention, examples of Meta Data are users, applications, application attributes, time of day, user preferences, etc. The Meta Data is defined in an XML format so as to be self-describing. The method uses a Parameter Driver Dynamic Rules Based System. This system can have an arbitrary number of rules. Each rule evaluates to a Boolean result. The logical ANDing of the results of all the rules evaluates to the final Boolean result. Each rule is made up of parameters which are evaluated at runtime to determine the final result. A Parameter Driver Dynamic Rule will look like the following:

  Method for Location Based Privacy using Meta Data and Parameter Driven Dynamic Rules

   This publication defines a method for Location Based Privacy using Meta Data and Parameter Driven Dynamic Rules, for applications which use the current location of the wireless device initiating the application request.

Privacy is of the essence in Location Based Services. Users need to have control over the who, what, when, where, and how their location is shared. This method exploits the use of Meta Data and a Parameter Driver Dynamic Rules Based System to provide a privacy solution for location-based services.

In this invention, examples of Meta Data are users, applications, application attributes, time of day, user preferences, etc. The Meta Data is defined in an XML format so as to be self-describing.

The method uses a Parameter Driver Dynamic Rules Based System. This system can have an arbitrary number of rules. Each rule evaluates to a Boolean result. The logical ANDing of the results of all the rules evaluates to the final Boolean result. Each rule is made up of parameters which are evaluated at runtime to determine the final result. A Parameter Driver Dynamic Rule will look like the following:

(ApplicationABC is a location based application) AND (ApplicationABC is allowed to receive UserXYZ location) AND (Time of Day is between 8:00am - 5:00pm) AND (Location is Raleigh) )

Note: italics indicate parameters dynamically evaluated at runtime
