Abstract
A method and system for effecting a security web upon multiple devices. In one embodiment of the invention, multiple devices are enabled to respond as authorized members of a security web such that each device acts as a co-monitoring device within the web. Further, each device transmits an identifiable RF signal at regular time intervals and is enabled to search for the transmitted RF signal from every other device within the security web. Next the invention determines a non-authorized loss of proximity from the web of any of the devices of the web. Upon determining a non-authorized loss of proximity of any device, the invention provides for at least one of the devices of the web to initiate an event.
