Abstract:
In this paper, a novel image encryption scheme based on quick response code and interference in Fresnel domain is proposed. The framework is asymmetric in nature due to amplitude- and phase-truncation operation of encoded spectrum. The input image is scrambled using Arnold cat map and divided into pixel blocks. Each block is encoded into a quick response code, which are then multiplexed to generate a binary matrix. The phase-truncated binary matrix is encoded into analytically generated two phase-only masks. During decryption the phase-only masks are recombined to yield the binary matrix, which is grouped into quick response codes and decoded into pixel blocks. The pixel blocks are recombined and descrambled to retrieve the original image. Numerical simulations have been carried out to demonstrate the effectiveness of the proposed method.

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
