Using GPS for Proximity Detection to Improve Personal Safety, Monitoring Surveillance Disclosed is a method and system to provide for proximity detection mechanisms between connected individuals. Currently, there is no mechanism available where a third party like a parent can periodically make sure that two persons like a baby sitter and the child being cared for are in close proximity to each other. In the disclosed system, some third party such as a parent of a child can monitor the child's proximity to his/her baby sitter. In this disclosure we propose a system to alert the third party if a certain threshold of distance is exceeded so the third party or any authorized person can take appropriate action. The key is to enable the trackable entities such as the child and baby sitter with trackable devices such as GPS enabled Cell phones or PDAs, to relay their corresponding positions to a monitoring server. The server will track and record the corresponding positions of the entities to make sure they are in close proximity. When a certain threshold is exceeded, the server sends an alert to the third party monitoring the positions of the entities and/or to other interested parties such as law enforcement agencies.
