Abstract : Cloud based IoT is drawing more attention in recent days because of its potential in day today life. Infrastructures based on Cloud suffer from latency, security and privacy issues so does IoT. Fog computing reduces the necessity of transmitting confidential data to cloud by deploying nodes with computational and storage facility near to end user. Fog-IoT structure overcomes the latency problem and supports real time applications. Fog-IoT increases quality of service but introduces some new security and privacy challenges. The paper discusses the privacy issues introduced by fog nodes, existing privacy preserving mechanisms and some solutions for lightweight privacy preservation.
