Study and implementation of search mechanisms for decentralized online social networkLe Thanh Nha

Abstract

Online Social Network (OSN) has been a mean for people to communicate and keep contact with each other. More and more individuals are joining, using and even earning from OSNs. Thus, it is undeniable that OSNs have brought many benefits to users. There are, however, some privacy considerations (ownership) and limitations from its architecture (scalability). The formation of Decentralized Online Social Network (DOSN) is to resolve these problems. Currently, some services have been implemented for DOSN such as text-based posting and uploading services. One of the most important factors, however, is search mechanism. It is such a necessary service for any kind of social networks because it helps people to discover things around. The objective of this report is to propose a search approach for DOSN based on Gnutella protocol, which will enable users to search for specific information (statuses, comments, contacts and shared files) under privacy and access controls.
