| Résumé : |
The volume and diversity of data created each year by both humans and machines are increasing. Big Data now has uses in almost every area, including commerce, healthcare, financial services, government, agriculture, and so on. Overall, there is a high need for Big Data across all industries and enterprises. Sharing and analyzing Big Data raises several security issues and increases privacy risks, as a result of its decentralization and security. Despite the exponential growth, the tools and technology developed to manage huge data volumes are not designed to fulfill security and data protection standards. Furthermore, the majority of existing Big Data security systems are provided by a centralized third party, making them open to a wide range of security risks. In recent years, the integration of Big Data with Blockchain technology has been a big topic.Because of its decentralization and security, Blockchain has the potential to improve Big Data services and applications. The information in the network is safe and cannot be modified; also, using Blockchain to store vast amounts of data may make the data more structured and valuable. To demonstrate the integration of Big Data with Blockchain, we chose the banking sector for this project since it is the most attacked sector and requires advanced security measures. In this regard, the purpose of this project is to propose a Blockchain solution to financial data management byutilizing Blockchain security mechanisms. |
