Maintenance of Personal Health Record System with Cipher text Policy Attribute-Based Encryption and Quick Decryption

Abstract

The meteoric rise of information technology coupled with the pervasive use of cloud computing across all industries has prepared the road for the implementation of Personal Health Record (PHR) Systems using cloud computing. The greatest example to utilise is Microsoft Healthvault, which is an online personal health record service offered by the technology giant Microsoft. This service allows users to save, access, and update their personal information, which can then be shared with health care professionals. Some people believe that shifting applications that deal with personal data to cloud computing might result in a loss of control over the data. Therefore, it is essential to have PHR systems that are safe and stored on the cloud. Several frameworks for PHR have been developed, several of which make use of conventional cryptographic methods. However, they are not suitable for the PHR systems since they do not meet the requirements for efficiency, scalability, and appropriateness. Nicely addition, the single owner scenario of standard cryptographic approaches does not fit in with the multi-owner situation of the PHR system. As a result, we propose a PHR framework in which patients have access control and privacy of their personal record using a light weight 64 bit block cypher symmetric encryption algorithm. Additionally, we propose dividing the patient-centric framework into multiple security domains in order to reduce the complexity of key distribution. The plan that has been suggested is adaptable since it enables for break glass judgements to be made in the event of an emergency situation. However, the system does not have integrity, which is something that may be maintained by utilising a digital signature method or an Elliptic Curve Digital Signature Algorithm (ECDSA) scheme to establish integrity of the personal health information.
