PRODUCT AUTHENTICATION USING QR CODE WITH THE HELP OF RSA ALGORITHM

The advent of online shopping has led to a surge in ecommerce websites offering products from well known brands at very competitive prices. However, the cases of fake products and duplicity have also seen an increase in recent years, because of lack of proper mechanism to ensure authenticity of the products, whether purchased online or from a physical shop. In spite of the availability of a number of techniques and technology, there is still no means to check the delicacy occurring due to copying product information and generating fake QR codes, barcodes etc and using on fake or duplicate products. In this paper, we propose a methodology for product authentication by using the RSA algorithm on QR code. RSA involves a public key and private key. The public key can be known to everyone- it is used to encrypt messages. Messages encrypted using the public key can only be decrypted with the private key...
