Modified Generalized Random Grids-Based Progressive Secret Sharing with Lossless Ability for Binary Image
Heri Prasetyo, Didi Rosiyadi, Shi‐Jinn Horng · 2018
This paper proposes a new technique on progressive secret sharing which extends the generalized random grids to generate a set of shared images. The proposed method has lossless ability in the recovery process of secret image. This approach exploits the simplicity of bitwise-based computation. As reported in the experimental section, the proposed method yields better results compared to the former existing scheme under visual investigation and objective assessment on the recovered secret image. Yet, it can be regarded as good candidate for applying the progressive secret sharing with lossless reconstruction constraint.
