USER CENTRIC APPROACH TO IDENTITY MANAGEMENT IN CLOUD COMPUTING ENVIRONMENT: AN EMPIRICALLY TESTED FRAMEWORK

Abstract

Most of the commercial identity management models have focused on the perspective of service providers and given a preference to the challenges faced by the service providers. However, with the growing number of concerns, an identity management system with strong focus on the user’s concerns is required. A User Centric Approach for Identity Management (UCAId) for Cloud Computing in SaaS Environment has been presented in this paper. The proposed UCAId model considers user at the central position to improve their experience and increase adaptability of the cloud. Comprehensive literature review has been carried out to identify the most important parameters of the User Centric Identity management. Provisioning, privacy, security, scalability and trust have been identified as the five most parameters and further the model presents these parameters built-up on the strength of eight components each, individually. The model has been empirically tested to see its user adoption on a set Indian users with varied demographics. Data has been collected using a structured questionnaire and Principal Component Analysis has been used to analyze this primary data.
