A Visual Cryptography Scheme (VCS) is a unique data hiding technique aimed at decomposing secret information into multiple images, referred to as shares. These individual images, when viewed in isolation, are incapable of revealing the contents of the secret. The original secret information can only be reconstructed when multiple images are overlaid. The distinguishing feature of this method lies in the distribution of these shares. They individually appear as random noise. It ensures that access to any part of the secret information is only possible when all shares are combined. In this paper, we propose a Visual Cryptography Scheme enhanced with surface cover and apply it to door lock systems, effectively enabling efficient identity management and verification. Through this technology, the system can guarantee that access permissions are granted only to authorized individuals.
