Qr Sharing: A New Approach In Security Using Visual Cryptography And Quick Response Codes
Nowadays online transactions h a v e become very common but there are various attacks present behind
this. Thus, the security in these cases needs to be very high and should not be easily vulnerable for outside attacks.
Our work proposes a scheme that attempt to collaborate Quick Response (QR) and Visual Cryptography (VC) together
to improve the transmission of secret messages i.e. OTP via different medium as a means of authentication which may
have more practicality in terms of real world usage. QR codes are basically two dimensional barcodes embedded with
data that can be decoded quickly for information. In this work, we show that QR codes can be used for secret
communication using VC. An interesting feature of our work is that we present a technique to convert QR codes into
carriers for secret messages using VC. VC provides a way of sharing secrets between a numbers of participants. The
secrets are in the form of an image that is encoded into multiple pieces known as shares. When these shares are
superimposed, the secret can be instantly observed. Communicating secret messages in plain sight creates a credible threat
to our national security. We hope that our work brings this issue to light and enhances counter-terrorism education.
