Abstract: A personalized security system in which a portable transmitter may be carried or worn by an individual and activated by the individual when in need of assistance to transmit data relating specifically to the individual. The data is received by a transceiver located in close proximity to the individual such as at an ATM, pay phone, gas pump or personal computer and is transmitted with additional data to a remote receiver. The remote receiver then forwards information relating to the data to emergency personnel who use the information to determine the location of the individual, as well as particulars relating specifically to the individual, such as name and physical description.
