Abstract: An identity monitoring system notifies legal guardians of potentially fraudulent activity associated with their children's identities. The monitoring system may determine if credit files for respective enrolled minors exist and monitor any credit files of the enrolled minors, such as via periodic requests for credit data and comparison of certain returned credit data, in order to determine if potentially fraudulent activity associated with the minor has occurred. The monitoring system provides periodic notifications, such as via email and/or Internet-accessible user interfaces, regarding potentially fraudulent use of their children's identities. In one embodiment, the monitoring system also provides legal guardians with useful information and resources for how they can further protect the identity of their children.
