Survey on Secure Image Sharing by using NVSS

Before NVSS the traditional visual secret sharing (VSS)was used. The traditional Visual Secret Sharing schemes hides the images in the shares that are either printed or digital form  ,these shares can be appeared as noise pixel or meaningless images .Hence this scheme suffer from a transmission risk problem for the secret image itself and for participants who are involved in the VSS scheme. To overcome this problem, the Natural Visual Secret Sharing scheme is introduced .in this we share the secret images via various transmission media to protect the secret and participants during the transmission phase. The noise image is generated based on these natural shares and secret image In this we find out possible ways to hide noise like share to reduce the transmission risk problem for the share.
