Abstract:
With the advent of mobile technology, providing accurate information at a critical time for those in need
has become easy. People moving around in the crowd may get lost or face medical emergencies due to previous health
problems. In such a scenario, the mobile technology can be deployed to provide information to those who are lost or
need emergency medical help. This study presents a real-time system based on Quick Response Code specifically designed
for any crowded environments where there is a requirement for people to be assisted for navigating to their respective
destinations. Compressed and encrypted information about individual participants is encoded in the Quick Response
Code and is provided to them. If somebody in the crowd is lost or injured, volunteers and organizers can use smart
phones to scan this Quick Response Code to retrieve information and provide the necessary help. The same system can
also be implemented for any other scenarios like huge exhibitions, airports, shopping malls or even the battlefields
where there is a chance of an individual getting lost or requires direction.
