RETRACTED ARTICLE: Enhanced semantic visual secret sharing scheme for the secure image communication

Sharing multimedia information through the means of internet has increased many folds in this digital world. Information needs to be send across various secure channel as it contains sensitive data such as bank account details, medical reports or any financial documents. Due to the importance of information sharing, security is the most important objective that needs to be addressed while sharing this sensitive information. In order to share the information securely, one such way is visual secret sharing or visual cryptography. In this paper, introduced Enhanced Semantic Visual Secret Sharing (ESVSS) Scheme that transmits a gray-scale secret image to the receiver using two color cover images. At the receiver end, the secret image is reconstructed by digitally stacking the shares together. The result analysis shows that the ESVSS achieves security and improves the quality of the reconstructed image. The quality is measured by Peak Signal to Noise Ratio (PSNR) up to +39 dB and Mean Square Error is reduced to 6. The Universal Image Quality Index (UIQI) results are recorded up to 90% for the reconstructed image with minimal computational complexity.
