Privacy can be a key aspect of the user experience with computers, online systems, and new technologies. Knowing what to consider about users and their views of computer systems can only improve privacy mechanism. Human Computer Interaction (HCI) is the sub field of Computer Science that studies how people interact with and through computational technologies. In this paper, a three-level model-based approach is provided for the end user privacy in the human computer interaction as the end user’s privacy in the area of HCI is emerging as critical design element for interacting systems in areas as diverse as e-commerce, health care, office work, personal communications etc. The data privacy of end user as well as the resource access privacy is needed to be considered. As of now, no proper solution exists for all types of interface users which is a major privacy issue. Hence, to provide the end users, their personal data protection as well as the resource access security, this paper focuses on analyzing and developing the theory of technological acceptance related to user privacy
