Visual secret sharing by using generalized random grids is a novel approach for generating non-expansible shares by artfully utilizing various random variables. Stacking the shares together, secret image can be revealed. This paper proposes a 2 out of 3 visual multiple secret sharing method using generalized random grids. Three secret images (A, B, C) are used for generating three non-expansible shares (U, V, W). The secret revealing process is a kind of circle-style decoding: stacking U and V together, A can be revealed; stacking U and W together, B can be revealed; stacking V and W together, C can be revealed. The quality of stacking results can be adjusted by users for various applications.
