Securing Colour QR Code using Visual Cryptography

Abstract

The Quick Response code (QR code) is a two-dimensional matrix barcode that can encode data in four distinct ways (numeric, alphanumeric, kanji, binary). These days, they are extensively used and can be found almost anywhere, whether on cosmetics goods, everyday items, signs, and so forth. It has developed into a significant component of daily life. It is now possible to access the information saved in a smartphone with just one check thanks to the medium's increased usability and mobile friendliness._x000D_ This work's primary goal is to protect QR codes from unauthorized access by limiting access to those who are approved using encryption (by encrypting and decrypting the QR code using a key value). Additionally, protection the colour QR code is widely used for security purpose. They are currently commonly used and may be seen almost anywhere, whether on cosmetics, everyday things, signage, and so on. It has developed into a significant component of daily life. It is now possible to access the information saved in a smartphone with just one check thanks to the medium's increased usability and mobile friendliness. The primary objective of this study is too secure QR codes from unauthorized access by restricting access to those who are permitted using encryption (by encryption and decrypting the QR code using a key value). Additionally, protection the color QR code is widely_x000D_ used for security purpose.
