Narrow Results

Presented in this paper is a possible solution for speeding up the integration of various data in the big data mainstream. The data enrichment and convergence of all possible sources is still at the beginning. As a result, existing techniques must be retooled in order to increase the integration of already existing databases or of the ones specific to Internet of Things in order to use the advantages of the big data to fulfill the final goal of web of data creation. In this paper, semantic web-specific solutions are used to design a system based on intelligent agents. It tries to solve some problems specific to automation of the database migration system with the final goal of creating a common ontology over various data repositories or producers in order to integrate them into systems based on big data architecture.

Both blockchain and disseminated registering are expecting a basic part in changing endeavors’ work environments and the way standard handling works. Their rise has not quite recently gained energy in the current business establishment yet has furthermore changed the way the universe of usage headway, storing, online trade, and various organizations limits. Regardless, challenges suffer in the wide execution of blockchain in cloud. This book area plans to introduce the impact of blockchain on cloud and how to diminish.

Blockchain provides privacy and security without centralized authority. This work analyzes cryptography applications in blockchain and analyzes efficient sharing of health records using Attribute-Based Encryption (ABE). Secure data sharing of sensitive information stored in cloud is very important as anybody can access it from anywhere in the world. This work aims to provide a secure sharing of medical records in cloud using enhanced Ciphertext Policy (CP-ABE) and Key Policy (KP-ABE) techniques along with data owner specifying the access control policies. In an open-networked system, machine learning algorithms are effectively used in pharmacovigilance to find the Adverse Drug Reaction (ADR). Securing this sensitive data in cloud is very important as PHRs privacy concern is very important.
