        abstract = {— With the rapid growth of digital technologies, file sharing has become an essential part of communication in educational institutions, corporate organizations, and personal applications. However, the increasing dependence on online platforms has also raised serious concerns regarding data security and privacy. Many existing file-sharing systems rely on traditional authentication methods such as passwords or publicly shared links, which are often weak and vulnerable to unauthorized access, data interception, and misuse. As a result, sensitive information can be easily exposed, leading to data breaches and loss of confidentiality.

To address these challenges, this project presents a secure file sharing system that integrates Advanced Encryption Standard (AES) encryption with QR code technology. In the proposed system, files are first encrypted using AES, ensuring that the data remains unreadable to unauthorized users even if the file is intercepted during transmission or accessed without permission. To further enhance security, the encryption key or secure access information required for decryption is embedded within a QR code. This QR code is shared only with authorized recipients, allowing controlled and secure access to the encrypted file.

The use of QR codes simplifies the process of secure key distribution while reducing the risk of key exposure. Authorized users can scan the QR code using a standard device to retrieve the required information and decrypt the file safely. This combination of strong encryption and QR-based access control provides an additional layer of protection without increasing system complexity. The proposed system offers improved confidentiality, prevents unauthorized access, and ensures secure data transmission. It is suitable for applications where data privacy and security are critical, such as academic document sharing, business communication, and cloud-based storage systems.},
