SYSTEM AND METHOD FOR MONITORING FRAUDELENT TRANSACTIONS AT MERCHANT LEVEL IN REAL TIME PAYMENT

Disclosed herein is a method and system providing Merchants direct access to the powerful issuer authorization rules engine to evaluate and block card payment transaction in real-time from potential fraud at checkout. The access to the intelligent rules can be made by enabling a secure connection to the Risk Manager (RM). The real-time data will empower the Merchant to not forward the fraudulent transaction onto the acquirer for further processing, saving the transaction processing fees as eliminating back-office overheads on failed payments

Integrating Blockchain with Fog and Edge Computing for Micropayment Systems

Fog computing eliminates the need for a centralized cloud data center as it allows computation to be done by nodes closer to the edge. This helps in improving scalability, latency, and throughput compared to traditional cloud environment. Furthermore, with massive increase of IoT devices in the coming future, current solutions that consider centralized cloud computing may not be suitable. Blockchain has developed as a powerful technology enabling unlimited application and opportunities during the last decade. As both blockchain and fog computing technologies operate on a decentralized framework for operations, their integration can help in driving many technologies forward and provide tremendous advantage in terms of security and cost. Recently, micropayments are adopted into a large number of applications. However, individually processing micropayments will result in higher transaction fees where in some cases transaction fee can exceed the payment value. Due to this reason, traditional cryptocurrency blockchain like Bitcoins is inappropriate for micropayment transactions. As such, using fog computing for micropayment can improve the latency and scalability. On the other side, the increased speed and connection density offered by 5G technology will enable real-time processing of data as well as automated transaction processing between connected devices. The 5G technology will enable the smart devices to make micropayments by processing data more efficiently. This will have far-reaching impact on business financial management. The 6G networks will exhibit more heterogeneity than 5G enabling different types of devices to communicate in an efficient way. This will enhance the micropayment networks where different types of IoT devices will be able to connect and hence process payments and transactions in a more secure way. Integrating this intelligence with big data in blockchain and fog computing will change the traditional business models and support the creation of efficient and fast micropayment systems.This chapter explains the benefits of integrating modern technologies (fog computing, blockchain, 6G, and IoT) to solve the problem of micropayment systems. This is achieved by utilizing the capabilities of each technology (e.g., edge computing, blockchain, evolution of 5G to 6G) to bring intelligence from centralized computing facilities to edge/fog devices allowing for more envisioned applications such as micropayment systems where reliable, cheap, high speed, secure, and reduced latency transaction processing can be achieved. The chapter also highlights the various relationships among these technologies and surveys the most relevant work in order to analyze how the use of these disruptive technologies could potentially improve the micropayment systems functionality. Furthermore, various forms of integration of these technologies and associated applications are discussed, and solutions/challenges are outlined. The chapter also briefly discusses a generic solution to the problem of micropayments by integrating fog computing capabilities, blockchain, and edge computing to provide a practical payment setup that allows customers to issue micropayments in a convenient, fast, and secure manner

BlockChain: A distributed solution to automotive security and privacy

Interconnected smart vehicles offer a range of sophisticated services that benefit the vehicle owners, transport authorities, car manufacturers and other service providers. This potentially exposes smart vehicles to a range of security and privacy threats such as location tracking or remote hijacking of the vehicle. In this article, we argue that BlockChain (BC), a disruptive technology that has found many applications from cryptocurrencies to smart contracts, is a potential solution to these challenges. We propose a BC-based architecture to protect the privacy of the users and to increase the security of the vehicular ecosystem. Wireless remote software updates and other emerging services such as dynamic vehicle insurance fees, are used to illustrate the efficacy of the proposed security architecture. We also qualitatively argue the resilience of the architecture against common security attacks

A blockchain protocol for authenticating space communications between satellites constellations

Blockchain has found many applications, apart from Bitcoin, in different fields and it has the potential to be very useful in the satellite communications and space industries. Decentralized and secure protocols for processing and manipulating space transactions of satellite swarms in the form of Space Digital Tokens (SDT) can be built using blockchain technology. Tokenizing space transactions using SDTs will open the door to different new blockchain-based solutions for the advancement of constellation-based satellite communications in the space industry. Developing blockchain solutions using smart contracts could be used in securely authenticating various P2P satellite communications and transactions within/between satellite swarms. To manage and secure these transactions, using the proposed SDT concept, this paper suggested a blockchain-based protocol called Proof of Space Transactions (PoST). This protocol was adopted to manage and authenticate the transactions of satellite constellations in a P2P connection. The PoST protocol was prototyped using the Ethereum blockchain and experimented with to evaluate its performance using four metrics: read latency, read throughput, transaction latency, and transaction throughput. The simulation results clarified the efficiency of the proposed PoST protocol in processing and verifying satellite transactions in a short time according to read and transaction latency results. Moreover, the security results showed that the proposed PoST protocol is secure and efficient in verifying satellite transactions according to true positive rate (TPR), true negative rate (TNR), and accuracy metrics. These findings may shape a real attempt to develop a new generation of Blockchain-based satellite constellation systems
