The growth in internet of items (IoT) use in big data is exponential, and a large number of these devices are expected to be monitored in various domains for different applications. Therefore, high traffic volumes and safety standards and procedures must be managed by the servers. Although many mechanisms are in place to protect the data transmitted, they are not enough to satisfy the data requirements. This work therefore aims to enhance the security and privacy of IoT communications among big data through the implementation of server privacy and the development of unique signatures using device attributes.These features may be constant depending on the user, but when the device communicates, identity changes to protect privacy. To allocate IDs based on the IoT device attributes, a special server called the Attribute Management System (AMS) is used. Depending on data type and transfer length, three different algorithms are used. This latest, secure IoT device design communication offers safe big data confidentiality.
