Security Enhanced Personal Health Record Sharing Mechanism in a Cloud-Based System

This paper presents an effective VSS mechanism for sharing medical images and associated data. Here, a random grid-based approach is used for share generation, and the PBTL method hides the associated text in the image. As the generated shares are stored in a distributed manner, the proposed method completely avoids single-point attacks. The proposed method exhibits good reconstructional quality and security. The algorithm requires all the generated n shares to reconstruct the initial image. This property enhances the algorithm’s ability against brute force and other statistical attacks. The main drawback of the system is the inability to reconstruct the original image in the case of share tampering. So, our future work will concentrate on tamper detection and self-recovery of shar
