Secure Integrity Auditing System for Electronic Patient Health Records using Advanced Encryption Techniques

Abstract

Abstract: Cloud computing is one of evolving technology nowadays, giving versatile services. However, secure information sharing is vulnerable to cloud computing. With cloud storage services, users can remotely keep their information to the cloud and recognize the data sharing with others. Electronic wellbeing record (EHR) is a framework that gathers patients' computerized wellbeing data and offers it with other medical care suppliers in the cloud. Since EHR contains a lot of critical and delicate data about patients, it is necessitated that the framework guarantees reaction accuracy and capacity respectability. The verifiable database (VDB), where a user’s redistributes his huge data set to a cloud worker and makes questions once he needs certain information, is proposed as an effective updatable distributed storage model for asset compelled users. To improve productivity, most existing VDB plans use confirmation reuse and evidence refreshing strategy to demonstrate accuracy of the question results. Notwithstanding, it overlooks the "continuous" of confirmation age, which brings about an overhead that the user needs to perform additional cycle (for example evaluating plans) to check stockpiling trustworthiness. In this paper, we propose a publicly verifiable shared updatable EHR database scheme that supports privacy-preserving using secure encryption and batch integrity checking.
