摘要：Graphical abstractVillages comprising a particular district will have their own granaries. The seller at each granary will have access to the database through an ID and password. The consumer at each granary will be verified through a triple security check: first through his/her Aadhar card and next through a biometric scan. After these steps, the data will be updated on the server, and an SMS will be sent to the consumer regarding his purchases. If at any of these steps the verification fails, the seller shall go back to the previous step. This model can provide a platform for reliable, secure and end user delivery system for all type users including non-educated users. It can also help protect cheating and corruption in food distribution system.Display OmittedAbstractIndia’s Public Distribution System (PDS) comprises ration shops which are responsible for distribution of ration to many poor families. Necessary commodities such as rice, kerosene, sugar, wheat etc., are supplied to the less privileged sections as per the eligibility and at fixed rates by the Indian government. However, the existing system suffers from major drawbacks such as storage of food grains, manual and inconsistent tallying of records against stock, black marketing and housekeeping. Hence, the conventional system needs some modification to ensure there is minimal wastage and food grains reach the right people. The major contribution of the hardware lies in acquiring records from the warehouses located in far off places to a centralized server managed by the administrator. This system also solves the problem of black marketing with the use of Aadhar cards and biometric scanning which are used for the verification of the consumer at the time of purchase. In addition to the above, another aspect of the system is the management of two types of databases, one of them is used for storing the data of the consumer and the other for maintaining the record of the availability of the ration in various warehouses which are located in different parts of the country.
