A location-based risk alerting system is disclosed. When information regarding a risk assessment situation is received, the location and time attributes of the risk assessment situation are extracted, a risk score is calculated and a risk alert is generated to include the attributes and the risk score upon validating the received information for risk. The risk alert is transmitted to client devices of subscribers where a user-specific risk score is calculated at each client device based on a comparison of the distance of the client device from the location attribute and the time at which the risk alert is received with the time attribute. The risk alert is displayed at the client device based on the user-specific risk score and information regarding the user is shared with trusted authorities upon receiving user consent.
