Abstract: “One-dimensional (1D) barcode stores data in only one direction (horizontally), whereas in two-dimensional (2D) barcode, data is stored in both the directions (horizontally and vertically). Also, the amount of data that can be stored in 2D barcode is significantly greater than that stored in a 1D barcode. Here, we propose an approach for Baggage Management at Airport using 2D barcode for the first time, so that the baggage(s) of two passengers looking alike will not be interchanged and also misplaced or lost baggage(s) can be handled properly. This approach is also beneficial for the authentication of ticket, boarding pass as well as baggage(s) with the minimum use of the database. For the authentication, we use a unique ID like passport number, PAN number, etc., which is encrypted with a master key (issued by the Airport Authority) in the ticket barcode (encrypted 2D barcode on the ticket), boarding pass barcode (encrypted 2D barcode on boarding pass) and baggage(s) barcode (encrypted”
