Secure Document Generation with QR Codes and Visual Secret Sharing

Here we generate a secured document using Quick response (QR) code &encrypt that QR code using Visual Secret Sharing (VSS) for further security. Visual cryptography is a secret sharing scheme which uses images distributed as shares such that, while the shares (i.e. 1 & 2) are fused, a hidden secret image is revealed. These share images are constructed to contain meaningful cover images, thereby providing opportunities for integrating visual cryptography and biometric security techniques.
