This paper presents the design, implementation, and evaluation of a secure file transfer management system built on the Linux platform. The system utilizes special group IDs to facilitate seamless communication between users while ensuring robust security measures. File manager is an API developed in Python, enabling efficient and reliable transfer of files from one user to another. The paper discusses the system’s architecture, highlighting the integration of special group IDs for user authentication and access control. Key aspects of the development process include emphasizing the challenges and solutions encountered in leveraging Linux-specific features. Security considerations, including access control mechanisms, are thoroughly examined to ensure the confidentiality and integrity of transferred files. Overall, this paper provides valuable insights into implementing a secure and efficient file transfer management system on Linux, offering practical guidance for developers and administrators seeking to enhance user-to-user communication in their environments using GUI.
