Abstract:
This paper introduces a secure storage scheme for healthcare data with multiple authorizations. The proposed design divides the healthcare data into small parts and distributes them over multiple cloud locations. The Shamir's Secret Sharing and Secure Hash Algorithm are employed to provide the security and authenticity requirements to the proposed design. The design comprises two phases, the distribution phase, and the retrieving phase. The distribution phase comprises three operations of dividing, encrypting, and distribution. The retrieving phase performs collecting and verifying operations. To increase the security level, the encryption key is divided into secret shares using Shamir's Secret Sharing. Moreover, the Secure Hash Algorithm is used to verify the healthcare data after retrieving from the cloud. The experimental results show that the proposed design can reconstruct a distributed healthcare data with a significant speed while conserving the security and authenticity properties.
