Multi-Dimensional User-Specified Extensible Narrowcasting System

摘要

Narrowcast communication to one or more narrowcast communication recipients is provided through the use of an extensible method and apparatus. A narrowcast communication sender determines a set of attributes that define who will be eligible to receive a narrowcast communication. The set of attributes characterize potential recipients according to qualities such as interests, location, or another descriptor of a potential narrowcast communication recipient. Through the use of a privacy sphere, attributes associated with the narrowcast communication are matched to the qualities of potential recipients to identify the network addresses of the narrowcast communication recipients. The narrowcast communication is then transmitted to those network addresses. The narrowcast communication can be then expired from recipients who are no longer eligible to receive it and transmitted to recipients who become eligible to receive the narrowcast communication.
