ABSTRACT:
Unauthorized distribution of data within a wireless communication system (101-102) can be detected by coupling a security gateway (103) between the wireless communication system (101-102) and a public data base system (104). When the public data base system (104) sends data to a requesting member of the wireless communication system (101-102), the data is intercepted by the security gateway (103). As the security gateway (103) is receiving the data, it is searching the data for a security tag. When a security tag is found, the security gateway (103) determines whether the security tag is assigned to the particular data base transmitting the data (105-106). If the security tag is not assigned to the particular data base, the security gateway identifies the particular data base as a potential unauthorized distributor of data (117).
