The paper "Secured IoT Based on e-Bulletin Board for a Smart Campus" by Anuradha, Bharathi Malakreddy, and Harinath addresses the limitations of traditional notice boards, such as the tedious process of updating information and the need for dedicated personnel. The authors propose an electronic bulletin board system using LED or LCD displays to display both text and multimedia messages entered by authenticated users. These messages can be viewed and deleted by authorized individuals, enhancing the efficiency and security of information dissemination. The system leverages the Internet of Things (IoT) to facilitate real-time updates and remote monitoring, making it suitable for smart campuses. The paper outlines the system's design, implementation, and results, comparing it with existing systems like those proposed by Alase and Chinchur, Khera, Shukla, and Ashavathi, and a GSM-based digital notice board. The proposed method aims to provide a more precise and cost-effective way to notify students and teachers, contributing to the overall goal of creating a smart campus environment.The paper "Secured IoT Based on e-Bulletin Board for a Smart Campus" by Anuradha, Bharathi Malakreddy, and Harinath addresses the limitations of traditional notice boards, such as the tedious process of updating information and the need for dedicated personnel.
