A system and method are described herein that includes a presence server
which is capable of notifying a watcher about a location of a person
using a rich presence element in accordance with security and privacy
rules specified by the person. In the preferred embodiment, the system
uses a read/write RFID tag and RFID reader as well as a presence server
to collect, store and distribute location information as a presence
element to the watcher. To accomplish this, the user data and program
carrying capability of the read/write RFID tag is used to push to the
presence server not only location information but also policies and rules
established by the user to control the distribution of the location
information as a presence element to watchers. The location policy rules
can be made and controlled by the user and/or a third party. The location
policies and rules are separate from the traditional and less stringent
presence policies and rules used by the presence server to control the
distribution other types of presence information like information about
the status of a person's communication devices to the watchers.
