Most of the enciphering structures are based on the transformation of mediums by describing the strict criteria. The presented article is based on Megrelishvili’s design and quantum spin states structure to offer privacy to digital contents. We have replicated the pixels of the image with the spin half states sequence for definite phase distributed with Megrelishvili protocol to create confusion in the anticipated mechanism. The choice of the offered work rotates around the improvement of a cryptosystem based on the notion of spin half algebra and Megrelishvili protocol. Moreover, we have tested the anticipated information confidentiality scheme by utilizing security analyses. © 2021, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.
