This research addresses the pressing challenge of securely sharing files between organizations, ensuring that sensitive information remains confidential and precise throughout its transfer. As organizations increasingly rely on internet-based document sharing, the need for robust security protocols to prevent unauthorized access has become paramount. This study proposes an advanced solution by integrating Attribute-Based Encryption (ABE) with blockchain technology to establish a decentralized and highly secure file-sharing system. ABE enforces access control based on the specific attributes and roles of users, ensuring that only authorized individuals can access the content. Simultaneously, blockchain provides a transparent, traceable, and immutable record of file transactions, which enhances the overall security framework by preventing tampering and ensuring data integrity. The system is designed so that only authorized users who meet predefined criteria can decrypt the shared files, thereby protecting sensitive data. By combining ABE and blockchain, this method significantly strengthens security, making it a powerful solution for organizations in need of secure document exchanges, while maintaining privacy and confidentiality.
