摘要：Segmentation based visual cryptography is segment based not pixel based and works on symbols that may be shown as segment display, the two major technique proposed in this category are seven segment and sixteen display. The major benefit of using Segment Based encryption is that “It is easy to adjust the secret images and potentially easy to recognize for the human eye”. In this paper we have summarised the various schemes for schemes for segment based visual cryptography given in figure 4 .We have analyzed majorly three techniques 1> Secret sharing, 2> symmetric key distribution 3> Seeded Region growing based segmentation. Future researchers may focus on automated seeding algorithms.
