In this paper, we aim to introduce the challenges that are faced to maintain the authentication and integrity in big data. Big data was developed to provide voluminous data while protecting the integrity of data. We further provide a comparative study on various methods which can help resolve the following issues. The comparative study is based upon a few parameters such as the scope, its prerequisites, advantages and disadvantages of the method.
The advances in the digital world has rendered the collection of colossal amounts of data called Big Data. This voluminous data if analyzed in an expedient way can help us gain valuable insights. On the other hand, securing Big Data has become an important aspect as it can lead to disastrous results if intercepted by intruders. Through this paper, we describe the management of authentication and access control by providing an overview of the existing protocols. Further, we propose a modified protocol which amalgamates the authentication and authorization processes there by speeding up the entire procedure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
