A Blockchain-Based Framework for Secure Secret Image Sharing in Wireless Networks

Secret Image Sharing (SIS) is a secure method of disseminating an image by breaking it into n shadow images where k number is required to reconstruct the image.The existing techniques of SIS suffer from a security loophole and inefficient storage and are susceptible to tampering.Thus, this paper proposes a Blockchain-based Secure and Optimized SIS (BC-SOSIS) scheme to overcome those issues.The scheme enables decentralized storage to resist tampering, tightly coupled with smart contracts to achieve authentication, along with efficient encryption that ultimately improves its security and performance.Furthermore, the security analysis as well as experiments carried out against BC-SOSIS validate it as a scalable and reliable solution for the secure digital communication.
