A Security Framework for the Mobile Application Using Color Barcode

The thorough objective of this work is to establish a QR code framework for a secret key-secured concept. It is based on the asymmetric key verification context. SSH, server QR code is used for website login. The client-side stored RSA private key for encrypting information by implementing QR code verification, but presently QR codes are in the form of two-dimensional images for encryption purposes. The cell phones take the image of the QR code of the user and send a cryptographic reply to the server for broad verification. The upheld shading QR code inside the portable application for misusing the cyan (C), fuchsia (M), and yellow (Y) print the channels, and for the print shading by red (R), unpracticed (G), and blue channels, severally, apply the catch the shading picture. The hiding process embeds the quantized QR code so that it will not cause any visible distortion in the cover images and hides the QR code inside a color image. The results show the proposed method has high imperceptibility, integrity, and security.
