Information generated by humans and machines is a major concern in the security and protection of information. However, currently the tools and processes designed to manage big data cannot meet these requirements. Most large security data is provided by third parties in the middle, making them vulnerable to security threats. Blockchain technology has emerged as a solution to these problems by providing decentralization, transferability, trust, proprietary information and traceability. In this study, we propose a new big data security solution that combines sharing, encryption and access control strategies and powered by blockchain technology. Our proposed shredding algorithm takes into account the need for data subjects to be encrypted to ensure optimum security. Additionally, we provide an additional layer of data protection by storing corrupted data in a distributed format. Our solutions increase the security of large files with minimal overhead, avoiding the encryption overhead for low-value and low-cost data. We present the results of our application, which shows the low up time load and important security and privacy considerations. Overall, our solutions provide a powerful and reliable way to protect big data.
