Abstract-Finding new ways to take advantage of big data, small or big organizations need high security techniques end efficient policies to guarantee their systems. In big data, it is very difficult to store data and analyse these data with conventional techniques. It is though that the traditional mechanisms are not efficient on big data security and privacy challenges. Different challenges include Hadoop security, cloud security and monitoring and auditing, etc. Big data deals with different data formats, data collection done from different sources, streaming of data may cause security problems the existing systems led to the violation of the individual privacy control. Data should be shared in a secure environment without violating people's privacy to overcome such complex issues, it is necessary to implement some set of rules and regulations in performing data sharing, authentication process, in generating personal information, and misusing of the system. With respect to these problems, proposed system introduced some mechanism challenging security and privacy issues for both user and application oriented.
