COLLABORATIVE INCIDENT ALERT SYSTEM FOR MOBILE DEVICES

An incident alert system enables a plurality of users to participate in a collaborative process to report and be alerted of incidents such as emergencies or hazards. A user uses a networked mobile phone with geo-positioning capability to communicate with a server to report incidents and to inquire about potential incidents of interest based on the user's current geographic position. Reports of incidents are transmitted to the server accompanied by the current position of the user/mobile phone. A user's mobile phone is preferably configured to automatically submit periodic inquiries to the server based on the user's location. Upon receipt of an inquiry from a user, the system queries a database to identify reports of potential interest to the inquiring user. The system analyzes the reports to determine whether to alert the inquiring user of a potential incident of interest.
