Paper Title
Patient Health Record System Using Attribute Based Access Control Technique
Abstract
The cloud computing offers the efficient and scalable computing and storages, using this number of traditional
and new generation applications are getting computational and storage benefits according their needs. In these applications
sometime more sensitive and confidential data are communicated, thus the data owners are worried about the leakage of data
or other privacy concerns. In addition of that in an organizational environment the similar authorities can access similar
kinds of data with the similar access rights. But it is required to provide the functionality to incorporate the user defined
privileges for securing the data confidentiality. This in this presented work the access control techniques and the security
concern are studied. The proposed work involves the addressing of problem using a PHR (patient health record) system. In
this PHR system three different kinds of users are implemented namely patient, researcher and doctor. Additionally for
regulating the access of the users to the data an ABAC (attribute based access control) technique is presented. The presented
technique provides the cryptographic data security and access control using the hybrid cryptographic approach. To design
the proposed ABAC model the tiger hash generation algorithm and the blowfish cryptographic algorithm is proposed and
implemented. The implementation of the proposed methodology is given using JAVA technology. Additionally for
deployment of the implemented technique the OpenShift cloud platform is used. Finally for comparison of the cryptographic
technique a SHA1 and DES algorithm based model is compared with the proposed model using the encryption and
decryption time and space complexity. According to the gained experimental outcomes the proposed technique found
efficient as compared to traditional cryptographic model.
Keywords— PHR, access control, cryptography, implementation, ABAC models.
