Abstract
Nowadays, Big Data (BD) is one of the advanced areas of Information Technology (IT) sector. BD can be explained as a large volume of file or data. Since there are many hackers and malicious users over the internet, it is very important to distinguish between the authorized and unauthorized users for securing the confidentiality of BD. Access control method allows data accessing of an authorized user. In recent years, file or data access control is a very challenging issue in BD. Existing access control schemes mainly focus on the confidentiality of the data storage from the unauthorized users. In this paper, a novel file or data access control scheme has been presented. The proposed scheme allows reducing the searching cost and accessing time, while providing BD to the user. It also minimizes the problem of data redundancy.
