There are numerous serious concerns in the growth of IoT, especially in the regions of privacy and security. Hence a smart IoT based notifier is being developed to address these issues. This project’s vision involves enhancement of the existing technologies used in our department for notifying the various staff members on being called by our head of the department. Traditionally it involves an alarm to be used by the head of the department to inform his personal assistant to notify the respective staff about the message. It can be improved by making a secure digital alarm which visually replicates a land line phone with buttons and LCD screen to enter the unique number assigned to each faculty and the enter button to confirm the submission of the number which via an application will notify the respective staffs on their mobile phones about the message to meet the head of the department immediately via wireless connectivity provided by the institution as our campus is 24x7 Wi-Fi enabled. Also, it is a secure device which involves fingerprint lock so that the device can exclusively be used by the head of the department only. Keywords: Internet of Things, Alarm, Notifier, Privacy, Security 1. INTRODUCTION The Internet of Things (IoT) is a technology transition in which devices allow us to sense and control the physical world by making the objects smarter and connecting through an intelligent network. The basic premise and goal are to connect the unconnected. The term was created by Kevin Ashton in 1999 to integrate the company’s supply chain with the Internet while working for Proctor and Gamble The Internet of Things has evolved as a result of the integration of multiple technologies, real-time analytics, machine learning, embedded systems, etc. Some of the real-time IoT applications are Connected Roadways, Connected Factory, Smart Creatures, Smart Connected Buildings, etc. In IoT, push notifications are small messages to the users in response to any action and are independent of sites. Pop-ups, on the other hand, appear only when users are on the site. This project’s vision involves the enhancement of the existing technologies used in our department for notifying the various staff members on being called b involves an alarm to be used by the head of the department to inform his personal assistant to notify the respective staff about the message. This involves manual work as well as can result in delays or errors as it involves human intervention. The current scenario can be improved by making a secure digital alarm which visually replicates a landline phone with buttons and LCD screen to enter the unique number assigned to each faculty and the enter button to confirm the submission of the number which via an application will notify the respective staffs on their mobile phones about the message to meet the head of the department immediately via wireless connectivity provided by the institution as our campus is 24x7 Wi-Fi enabled. Also, it is a secure device that involves fingerprint lock so that the device can exclusively be used by the head of the department only. This project will use no extra resources and can provide secure, fast, smart, and efficient communication between the head of the department and the staff members. The main objective of this project is to cut down human intervention and employ effective use of digitalization to minimize delay and miscommunication with negligible upfront costs for the resources to be applied. 2. LITERATURE SURVEY [1] Mobile technologies are used in institutes to facilitate services. This technology can play an important role in many fields such as m-Health. As such, providing services is an interesting research area. Moreover, according to the EM-DAT, the international disaster database provided by the Center for Research on the Epidemiology of Disasters (CRED), the number of technological disasters has decreased between 2010 and 2015 as. However, the total number of incidents accompanied with those disasters that include industrial, miscellaneous, or transport accidents, have increased as seen in Fig. 1b. [4]The augmentation of various sensors along with mobile computing and telecommunication systems provide a cheap, quick, and a flexible WSN that closely
