Publicly Verifiable Shared Dynamic Electronic Health Record Databases with Functional Commitment Supporting Privacy-Preserving Integrity Auditing

Project Code :TCMAPY1240

Objective

The project aims to revolutionize Electronic Health Record (EHR) systems by proposing an innovative Verifiable Database (VDB) model for efficient integration with the Internet of Things (IoT). The primary objectives include enhancing data integrity, minimizing computational and communication burdens for resource-constrained users in healthcare, and ensuring real-time proof generation. By modifying the Functional Commitment (FC) scheme and incorporating a dynamic group signature approach, the project seeks to establish a secure, updatable, and privacy-preserving EHR system, thereby advancing the reliability and efficiency of healthcare information management.

Abstract

This paper introduces an innovative Electronic Health Record (EHR) system addressing challenges of data integrity and computational burden posed by IoT devices. Employing a Verifiable Database (VDB) model, it ensures correctness and storage integrity while minimizing user communication costs. The proposed scheme utilizes a modified Functional Commitment (FC) design under the computational l-BDHE assumption, enhancing efficiency through real-time proof generation. Notably, it incorporates an efficient verifier-local revocation group signature scheme, enabling dynamic group member operations with features like traceability and non-frameability. This publicly verifiable shared updatable EHR database scheme offers privacy preservation and batch integrity checking, presenting a promising solution for resource-constrained users in the healthcare domain.
