Big Data draws the attention not only because of its great power but for the severe security and privacy challenges it brings. With the sources from various formats of user generated contents like digital video, blogging, forms, online social conversations, and so on, Big Data can be a strong tool to serve the users as well as attacking them. With the increasing applications of Big Data, profit-driven attacks are emerging rapidly, raising great challenges for data security, privacy, and trust. Hence, the recent research focus on Big Data Era has more emphasis on the protection of security and privacy. As the existence of the contradiction between large quantity of data with various formats and limited bandwidth and storage and computation power, the current defense solutions cannot resolve the problem entirely. So the conventional security mechanisms for small-scale or isomorphic data should be modified to adapt to the exponential increment of user generated data. It is important to develop new lightweight cryptographic algorithms (protocols), data mining, data organization and data optimization models, and performance evaluation methods to protect the security and the privacy of Big Data.
