Abstract

In the era of cloud computing, secure data storage and controlled data access are critical challenges. Traditional encryption techniques, while offering data confidentiality, often hinder efficient data retrieval and lack fine-grained access control. This project presents FABECS (Fully Attribute-Based Encryption Scheme for Cloud Storage), a secure, efficient, and privacy-preserving framework that enables encrypted data storage, searchable encryption, and attribute-based access control. FABECS incorporates an index-based searchable encryption mechanism that allows data users to perform secure keyword searches without revealing content to the cloud service provider. The system ensures only authorized users can decrypt and access relevant files based on predefined attributes, offering fine-grained security, low computational overhead, and scalability. Developed using Python and Django, and deployed on a cloud server, FABECS effectively addresses the limitations of existing systems while aligning with modern data privacy requirements.
