Abstract

Social networks are becoming popular, with people sharing information with their friends on social networking sites. On many of these sites, shared information can be read by all of the friends; however, not all information is suitable for mass distribution and access. Although people can form communities on some sites, this feature is not yet available on all sites. Additionally, it is inconvenient to set receivers for a message when the target community is large. One characteristic of social networks is that people who know each other tend to form densely connected clusters, and connections between clusters are relatively rare. Based on this feature, community-finding algorithms have been proposed to detect communities on social networks. However, it is difficult to apply community-finding algorithms to distributed social networks. In this paper, we propose a distributed privacy control protocol for distributed social networks. By selecting only a small portion of people from a community, our protocol can transmit information to the target community.

Highlights

Social networks are increasing in popularity, and people are sharing information with their friends on social networking sites (SNS)
We present decentralized private information sharing protocol (DPISP), an information sharing protocol used on social networks
On decentralized social networks or on SNS like Facebook, where users cannot directly access other people’s contextual information, our method provides a more realistic way to implement group communication functions using naturally organized communities

Summary

Introduction

Social networks are increasing in popularity, and people are sharing information with their friends on social networking sites (SNS). Ese mechanisms, require users to set access rights for all their friends in advance. This provides accurate solutions for deciding who should have access to certain information, it is inconvenient for a user to manage them, especially when a user has many friends. Lockr [21] provides access control on Flickr These mechanisms require users to define the access ability for each of their friends in advance. By placing each of the user’s friends into a predefined community, a user can share private information to only those in the target groups. By placing each of the user’s friends into a predefined community, a user can share private information to only those in the target groups. ey use cryptography to protect private information. is results in a complicated key exchange, and it will be difficult to revoke the keys when the connections on SNS are canceled
