A two-layer security model for accessing multimedia content in social networks

Abstract

Securing a website is nowadays one of the major concerns for system administrators. Security is also the most important challenge that Web developers have to face when designing a trustworthy platform to provide services for public users. It is well known that multimedia content on the Web is continuously growing and recently this media type is more and more commonly used in social networks. The access to multimedia content in the context of social networks should be both easy and secure. In this paper, a semantically-empowered security model for accessing multimedia content in social networks is presented. The application of this model ensures that (1) unauthorized users cannot access to private multimedia data, and (2) the overall level of trust among social networks users who share their private and sensitive data is enhanced. Two questionnaires were developed to select the most characteristic features to consider in our model to differentiate legitimate users and attackers. By using parametric considerations, both security and users' convenience are reached which makes our proposed model more effective.
