WEB CLOUD: WEB-BASED CLOUD STORAGE FOR SECURE DATA SHARING ACROSS PLATFORMS

Abstract

The rapid adoption of cloud storage has created a growing need for secure, accessible, and cross-platform data sharing solutions. Web Cloud is a web-based cloud storage system designed to provide end-to-end secure data storage and seamless sharing across multiple devices and operating systems. By implementing client-side encryption, robust access control mechanisms, and zero-knowledge architecture, the system ensures that users retain full control over their data while enabling secure collaboration. Web Cloud supports major web browsers and mobile platforms, allowing users to upload, store, share, and access files securely without depending on third-party trust for data confidentiality. It integrates AES-256 encryption, role-based access control (RBAC), and secure sharing links with expiration and password protection. The system addresses key challenges such as data breaches, unauthorized access, and platform fragmentation in traditional cloud storage services. Experimental results demonstrate high security, usability, and performance, making Web Cloud an ideal solution for individuals, enterprises, and organizations requiring secure cross-platform data sharing.
