Blockchain Based

Blockchain technology is increasingly used to enhance data security, privacy, and trustworthiness in various applications, particularly those involving sensitive information or complex data supply chains. Current research focuses on integrating blockchain with federated learning and differential privacy to enable secure data sharing and collaborative model training while mitigating privacy risks, including linkage and poisoning attacks. This work is significant for improving the accountability and transparency of data management across diverse sectors, from healthcare and finance to AI model development, ultimately fostering greater trust and compliance with data regulations.
