A Survey on Reduction of Transmission Risk & Extracting Digital Image for Sharing

Meeta A. Kukde, Prof. Pravin Kulurkar

Now a days in encryption/decryption process a natural -image-based VSS scheme (NVSS scheme) are proposed to shares secret images. In conventional method of VSS technique secret images that are stored in the form of digital, has shares which appear as noise pixel or sometimes a meaningful images. This increases the interception risk during the transmission of messages. In a natural -image-based VSS scheme (NVSS scheme), to reduce the transmission risk one way is that to hide the noise like share. NVSS scheme can share one digital secret image over n.1 arbitrary selected natural images, this selected images are called as natural shares. In a natural -image-based VSS scheme (NVSS scheme), the natural shares may in the form of photographic images, web images or hand painted pictures etc. The safe shares can be in digital or printed form and can be delivered to those who were involved in NVSS scheme process. This gives the safe natural shares transmission as compared to shares in another form like noise-like or meaningful shares. To share a digital image using various procedures and options, in NVSS scheme randomly chosen images are impervious in encryption phase, hence in NVSS scheme it is inoffensive as it is using only one noise share for sharing the secret image.
