摘要：

Visual cryptography is one of the emerging technology which has been used for sending secret images in highly secure manner without performing the complex operations while encoding. This technology can be used in the many fields like transferring military data, financial scan documents, sensitive image data and so on. In the literature different methods are used for black and white image which produce good result but for color images the quality of the decoded secret image is not good. In this paper, the system has been proposed which increase the quality of color decoded image. In this system sender takes one secret image which is encoded into n share images using Jarvis halftoning and encoding table. For decoding, the share images are used with decoding table to get original secret image. The average filter has been applied to decrease the noise introduced between encoding operation so that decoded secret image quality has been increased. The result analysis has been made by considering various image quality analysis parameters such as MSE, PSNR, SC, NAE and so on. The results are better than previous systems which are mentioned in the literature.
