In the digital transparent world, share the secret messages are challenged one. Visual cryptography (VC) is safer method for information transfer without any distraction by hackers. It is giving more security to the information sharing through digital form. This method hides the messages into images. So intruder cannot understand the distorted image and the data communication become secured. Through VC method number of shares has been generated from the original images. So here each RGB pixel shares are separately created by Visual Secret Share (VSS) scheme. The created multiple shares of the secret images are encrypted and decrypted with RSA algorithm. In the encryption process the multiplication technique is used for key generation process and public key is used for encryption process and private key is used for decryption process. Secret image’s quality has been compared through the Peak Signal to Noise Ratio (PSNR) and Mean Square Error (MSE) values. The experimental result of decrypted image PSNR value is 156.32 and MSE value is 0.5031. The Number of Changing Pixel Rate (NPCR) and Unified Averaged Changed Intensity (UACI) values are compared for the secure level of the secret image. The result of decrypted image NPCR value is 69.44 and UACI value is 13.88. Finally, the experiment result shows that the proposed method is giving more security and quality of secret image sharing and also execution time is faster than existing method.

在数字透明的世界里，分享秘密信息是一项挑战。视觉密码术 (VC) 是一种更安全的信息传输方法，不会被黑客分心。它为通过数字形式的信息共享提供了更多的安全性。此方法将消息隐藏到图像中。因此入侵者无法理解扭曲的图像，数据通信变得安全。通过 VC 方法从原始图像中生成了共享数。所以这里每个 RGB 像素共享是由 Visual Secret Share (VSS) 方案单独创建的。创建的多个秘密图像共享使用 RSA 算法进行加密和解密。在加密过程中，乘法技术用于密钥生成过程，公钥用于加密过程，私钥用于解密过程。已通过峰值信噪比 (PSNR) 和均方误差 (MSE) 值比较了秘密图像的质量。解密图像的实验结果PSNR值为156.32，MSE值为0.5031。比较变化像素率 (NPCR) 和统一平均变化强度 (UACI) 值的数量以获取秘密图像的安全级别。解密图像的结果 NPCR 值为 69.44，UACI 值为 13.88。最后，实验结果表明，所提出的方法提供了更高的秘密图像共享的安全性和质量，并且执行时间比现有方法更快。比较变化像素率 (NPCR) 和统一平均变化强度 (UACI) 值的数量以获取秘密图像的安全级别。解密图像的结果 NPCR 值为 69.44，UACI 值为 13.88。最后，实验结果表明，所提出的方法提供了更高的秘密图像共享的安全性和质量，并且执行时间比现有方法更快。比较变化像素率 (NPCR) 和统一平均变化强度 (UACI) 值的数量以获取秘密图像的安全级别。解密图像的结果 NPCR 值为 69.44，UACI 值为 13.88。最后，实验结果表明，所提出的方法提供了更高的秘密图像共享的安全性和质量，并且执行时间比现有方法更快。
