An Approach to Privacy Enhancement for Access Control Model in Web 3.0

Abstract

The recent web technology has been developed by three mainsprings which include integration, virtualization, and socialization. The web technology provides the increment of the social networking ability. However it deepens the exposure of privacy about personal information as more complicating and difficult problems. Representatively, it is impossible to define and manage the specific relation, so the personal information and interest can be inferred from collecting and summarizing the contents. Also, there are some problems that it is hard to construct the information owner's own social network. Thus this paper proposes the new access control model which enhances the user privacy of the existing access control methods in web 2.0. This method prevents privacy such as personal inclination from being exposed and enables to define and manage the specific relation. By doing this the information owners can construct their social network. This social network can be applied and extended to web contents.

The effects of ontology-based and password-protected blog access control on perceived privacy benefit and perceived ease of use

“…Lockr (Tootoonchian et al, 2008) used social relationships to control access in a Web 2.0 environment. Cho et al (2008) argue that privacy-enhanced access control is an effective method for controlling web data to protect privacy based on the tag ontology. However, no empirical data exist to evaluate these methods.…”

Sharing and hiding online secrets

“…There are several access control mechanisms, which can be used in social environments. For example privacy enhanced access control (PEAC) (Cho et al , 2008) is designed for Web 3.0. The PEAC model includes user, social network, tag, and web content.…”

“…Keeping secrets private within groups is important in online social activities. However there is no satisfactory access control mechanism for protecting private data in today's web systems such as blogs (Cho et al , 2008). The goal of access control mechanisms is to achieve confidentiality and integrity in information sharing activities (Ferraiolo et al , 2003; Samarati and Capitani de Vimercati, 2001; He and Antón, 2009).…”
