In the VGS system location and time are main constraints for helping in the user’s query. The users as well as the responders are volunteers who have already registered into the system. In the existing system the time constraint is not given preference. This project is to implement VGS with both location and time as the mandatory constraints. This proposed system is developed particularly for communication during emergency. User has to register in to the system by uploading a government authorized proof for validation of user by admin. The admin does this validation by taking the government proof id number and checks it with the database. Only if the id numbers are true then admin allows the user in to the system. Once admin allows the user, the user can upload query in the system. The timer starts counting down until the user gets the response. If there is no response then the area of safe zone is extended to some random square kilometers. After getting the response the user and the volunteer can communicate using the chat option. If the user found that the responder’s response is irrelevant to the query then the user itself can block the other user. If any user gets more than two blocks the admin will remove that user.
