ePrint Report: Privacy Preserving Records Sharing using Blockchain and Format Preserving Encryption

Sai Sandilya Konduru, Vishal Saraswat

Healthcare providers cannot share their patients' encrypted
data among themselves because of interoperability issues. Many blockchain-
based solutions have been proposed to allow for sharing medical data in
a privacy-preserving manner, but interoperability problems persist.
In this paper, we present a protocol called Blockchain-Format Preserving
Encryption (B-FPE) to preserve patients' data privacy. Each patient is
provided with an FPE key at the time …
