AB  - Multimedia Files (MFs) are widely used in communications which has large data volume of video and audio equipped with cell phones, laptops, cameras and other devices that using multimedia contents. It is highly challenging to provide security for multimedia communication. The traditional cryptography framework encrypts the entire multimedia file which was more complex, time-consuming and tedious process. Visual Cryptography (VC) is an innovative encryption technique used in the secure transfer of images and solves the problems of computational complexity. The study considers the problem of encoding a secret image into n shares of meaningful images. Researchers propose a new Semantic Visual Cryptographic Protocol (SVCP) that can encode the secret images into the shares using error reduction and LSB embedding procedure. The noises introduced by encoded secret pixels are totally reduced and will obtain the pleasing shares. The implementation part begins with converting a grayscale image into a semantic image through error reduction followed by embedding semantic image into n shares. Finally, secret image will reconstruct without showing any interference with the share images. The experimental result shows the effectiveness and advantages of the proposed SVCP and it ensures the security and quality of the reconstructed secret images.
