On multi-secret sharing using Hill cipher and random grids
Rokeya Begum Jothi, Aparajita Ojha · 2015
This paper presents a multi-secret sharing scheme using Hill cipher and random grids. The scheme is an extension of visual secret sharing scheme for gray scale images introduced in [13] by Chen. The proposed scheme provides increased security with lossless image recovery and no pixel expansion. Numerical results demonstrate the efficiency of the scheme.
