Survey on Privacy Preservation for Multi-Keyword Search on Data Network

In recent years, growth of private and semi-private information has grown rapidly on information network so, mechanisms to search such information have failed in privacy preservation. In todays emerging information networks, it is essential to find a solution for accessing the data from large number of providers while maintaining a privacy. So, there is a strong need to develop a technique which provides user required information in ranked order while preserving the users privacy. This paper analyzes different methods concerning about privacy of data in the public and private networks and also, analyzes a system based on public cloud platform where data sharing is takes place between public and private systems on a network through authentication and encryption. This system works on local private server which controls multiple systems. This paper is motivated by the lack of tools for an access controlled multi- search of data on the public and private network.
