Table-Free Visual Secret Sharing Technique with Arbitrary-Angle Stacking
Visual secret sharing technique is an absorbing strategy for embedding secret into shares. In this article, we have
proposed a multi-secret version without a predefined table and specific rotation angles. Particularly, the nearest-neighbor
interpolation is applied to modulate the coordinate of pixel after being rotated; thus, bringing in the achievement of
arbitrary-angle stacking. To the best of our knowledge, it is the first one of this property.
