A desktop application of QR code for data security and authentication

Initially the barcodes have been widely used for the unique identification of the products. Quick Response i.e. QR codes are 2D representation of barcodes that can embed text, audio, video, web URL, phone contacts, credentials and much more. This paper primarily deals with the generation of QR codes for Question Paper. We have proposed encryption of Question Paper data using AES Encryption algorithm. The working of the QR codes is based on encrypting it to QR code and scanning to decrypt it. Furthermore, we have reduced the memory storage by redirecting to a webpage through the transmission and online acceptance of data.
