Cloud Security Framework For Encrypted File Sharing With Qr Authentication

Abstract

With The Growing Adoption Of Cloud Storage For Secure File Management, Ensuring Data Confidentiality, Integrity, And Controlled Access Has Become Increasingly Important. This Project, "Cloud Security Framework For Encrypted File Sharing With QR Authentication," Introduces A Secure And Scalable System That Integrates AES (Advanced Encryption Standard) Encryption And QR Code-based Authentication To Protect Sensitive Information. Files Are Encrypted Before Being Uploaded To The Cloud, And A Unique Encryption Key Is Generated For Each File, Ensuring Data Remains Secure During Storage And Transmission. QR Code-based Verification Ensures That Only Authenticated Users Can Access And Decrypt The Files. To Further Enhance Data Integrity, The System Leverages Homomorphic Hashing Over An FTP-based Cloud Infrastructure, Enabling Secure And Verifiable File Integrity Checks Without Decrypting The Data. The System Also Maintains Detailed Logs Of File Access Attempts And Approvals, Ensuring Transparency And Accountability. By Combining Encryption, QR-based Authentication, And Cloud Storage With Secure Integrity Validation, This Framework Provides A Robust, Efficient, And Secure Solution For Managing And Sharing Sensitive Files In Cloud Environments. The Development Of This Project Leverages HTML And Bootstrap (CSS) For The Front-end, Ensuring A Visually Appealing And Responsive Design. On The Backend, Java And MySQL Have Been Employed To Establish A Robust Foundation For Data Management And System Functionality.
