PPS-ADS: A Framework for Privacy-Preserved and Secured Distributed System Architecture for Handling Big Data

The exponential expansion of Big Data in 7V’s (velocity, variety, veracity, value, variability and visualization) brings forth new challenges to security, reliability, availability and privacy of these data sets. Traditional security techniques and algorithms fail to complement this gigantic big data. This paper aims to improve the recently proposed Atrain Distributed System (ADS) by incorporating new features which will cater to the end-to-end availability and security aspects of the big data in the distributed system. The paper also integrates the concept of Software Defined Networking (SDN) in ADS to effectively control and manage the routing of the data item in the ADS. The storage of data items in the ADS is done on the basis of the type of data (structured or unstructured), the capacity of the distributed system (or coach) and the distance of coach from the pilot computer (PC). In order to maintain the consistency of data and to eradicate the possible loss of data, the concept of “forward positive” and “backward positive” acknowledgment is proposed. Furthermore, we have incorporated “Twofish” cryptographic technique to encrypt the big data in the ADS. Issues like “data ownership”, “data security, “data privacy” and data reliability” are pivotal while handling the big data. The current paper presents a framework for a privacy-preserved architecture for handling the big data in an effective manner

Cloud algebra : an innovative approach for managing resources, services and big data on clouds

In the current era of technological advancements, cloud computing is considered as one of the most promising computing paradigms. It is cost-effective, energy efficient, scalable and is location independent. In simple terms, a cloud computing technology provides various computing tools, facilities and mechanisms as a service to the end user. A user can opt for using these services as a pay-per-use model. This technology is indeed highly cost-effective, environment friendly and is a preferred option for those who don?t want to spend much on infrastructures, platforms or physical space required for setting up the enterprise. Cloud computing technology provides services like Software-as-a-Service (SaaS), Platform-as-aService (PaaS), Infrastructure-as-a-Service (IaaS), Computing-as-a-Service (CaaS) etc. Recently a new service called DaaS (Data-as-a-Service) has also emerged in which data is provided as a service to the users. This paper proposes a concept of creating algebra for the cloud computing environment called as cloud algebra (CA). Using the proposed cloud algebra we can perform several basic mathematical functions like addition, deletion, union, intersection and other aggregate functions on clouds directly. This means that using the proposed cloud algebra, two or more clouds can be added. One cloud may be joined with other clouds and two or more clouds can be compared and so on. Furthermore, the data stored on the clouds can also be effectively and efficiently managed using the proposed cloud algebra. Along with the data, the cloud services and resources can also be managed in a much effective and efficient manner using the proposed cloud algebra.5311-8814-F0ED | Sara Maria da Cruz Maia de Oliveira PaivaN/

SMS : a secure healthcare model for smart cities

Technological innovations have enabled the realization of a utopian world where all objects of everydaylife, as well as humans, areinterconnected to form an ?Internet of Things (IoT).? These connected technologies and IoT solutions have led to the emergence of smart cities where all components are converted into a connected smart ecosystem. IoT has envisioned several areas of smart cities including the modern healthcare environment like real-time monitoring, patient information management, ambient-assisted living, ambient-intelligence, anomaly detection, and accelerated sensing. IoT has also brought a breakthrough in the medical domain by integrating stake holders, medical components, and hospitals to bring about holistic healthcare management. The healthcare domain is already witnessing promising IoT-based solutions ranging from embedded mobile applications to wearable devices and implantable gadgets. However, with all these exemplary benefits, there is a need to ensure the safety and privacy of the patient?s personal and medical data communicated to and from the connected devices and systems. For a smart city, it is pertinent to have an accessible, effective, and secure healthcare system for its inhabitants. This paper discusses the various elements of technology-enabled healthcare and presents a privacy-preserved and secure ?Smart Medical System (SMS)? framework for the smart city ecosystem. For providing real-time analysis and responses, this paper proposes to use the concept of secured Mobile Edge Computing (MEC) for performing critical time-bound computations on the edge itself. In order to protect the medical and personal data of the patients and to make the data tamper-proof, the concept of blockchain has been used. Finally, this paper highlights the ways to capture and store the medical big data generated from IoT devices and sensors.5311-8814-F0ED | Sara Maria da Cruz Maia de Oliveira PaivaN/
