Big Data Security Analysis- A Study

Abstract

Although the use of Social Networking web sites and applications is increasingly on the rise, many users are not properly informed of the risks associated with using these sites and application. Understanding these risks and challenges should be addressed to avoid potential loss of private and personal information. Current authentication systems suffer from many weaknesses. Many available graphical passwords have a password space that is less than or equal to the textual password space. . In this paper, we present and evaluate our contribution, i.e., the 3-D password. The 3-D password is a multifactor authentication scheme. This paper examines the issues of security, privacy, and trust in social networking sites from users' viewpoint.
