Iot Based Smart Public Distribution System

Abstract

The system of providing basic domestic commodities on subsidy to poor families in developing countries like India is an
important aspect to meet fundamental requirement of people. Many problems are encountered by the existing system
such as, Ration distribution to unauthenticated card holders. Card holders wasting time in queues for collecting ration
for hours. Lots of malpractices such as hoarding, black marketing and overcharging. The project titled IOT based smart
public distribution system proposes an automatic method of distribution of commodities to authenticated card holders.
The users need to access to their account through the Smart phone by entering their ID and password. Once they are
successfully logged in, they can view the stock availability. This system uses Raspberry-pi as controller and it is
implemented with Minutiae extraction based fingerprint matching algorithm which efficiently works with greater
accuracy score. Once user is logged in, he/she can view commodities that is available for that particular family account.
To dispense the commodities, user is expected to provide fingerprint for next level of authentication. Once user is
verified, the system dispenses a threshold quantities of commodities for the particular family
