  In recent years, establishing secure visual communications has turned into
one of the essential problems for security engineers and researchers. However,
only limited novel solutions are provided for image encryption, and limiting
the visual cryptography to only limited schemes can bring up negative
consequences, especially with emerging quantum computational systems. This
paper presents a novel algorithm for establishing secure private visual
communication. The proposed method has a layered architecture with several
cohesive components, and corresponded with an NP-hard problem, despite its
symmetric structure. This two-step technique is not limited to gray-scale
pictures, and furthermore, utilizing a lattice structure causes to proposed
method has optimal resistance for the post-quantum era, and is relatively
secure from the theoretical dimension.
