Prevailing vulnerabilities and poor access mechanism can adversely affect security and integrity of any system. The proposed model is intended to develop a highly secure lock that can be configured according to the need of the required system. A three factor authentication model has been deployed (third factor is configurable) to make the system purely secure. The three factor authentication adds a additional layer of security to the already present two factor authentication model and therefore is hard to bypass or crack the system.

INTRODUCTION The proposed model is designed and developed to provide a highly secure lock based on the concepts of internet of things (IoT). 1.1 Background With the increasing number of security issues and breaches, now a day’s people focus more on how secure a product is. IoT security is of utmost significance as the consequences of security breaches in IoT devices can be devastating. A breach in a smart door lock can create dreadful situations for the owner. Even if there is a undetected breach which is not exploited but existing it will still give the product owner a phony sense of security which is ethically unacceptable. The security issues in IoT is a ever growing problem and though considerable research work is done in this topic but there is not much sustainable work about implementations that can solve the problem. 1.2 Problem Definition The security aspect of IoT connected devices is of higher significance. For a product owner to hold an acceptable implementation of the smart lock, we generalized the problems as follows - 1. How to setup a smart lock that is highly secure so that the breaching factor can be minimized ensuring strong privacy? 2. How to provide a user friendly interface and experience regardless of how complex the security architecture is? 3. How to develop a lock that can be configurable according to the need of any system? 4. How to provide a lock that is durable, reliable and efficient yet budget friendly? 5. How to develop a lock that can keep logs of all ethical and suspicious attempts to unlock the door? 1.3 Purpose The purpose of the proposed system is to develop a lock that runs on three factor authentication mechanism to provide its user a highly secure way to keep their stuffs safe. The model is designed as such the third factor of authentication is configurable and can be manipulated according to the need of access system. The configurable aspect of the lock gives wide fidelity to use it any scenario where a security is the priority. The logs of all the attempts should be recorded for future investigation. 2. MARKET STUDY The global smart lock market size was estimated at USD 559.4 million in 2016. The demand for smart locks is expected to exceed 135 million units by 2024. Rising adoption of connected home solutions and soaring need to establish connectivity across all electronic devices in users’ houses as a consequence of growing penetration of smart homes are among the key trends escalating market growth. Figure 2.1 – Market of Smart Lock (2013-24) From the above table it can be seen that the demand for smart lock is increased exponentially. Around 50% smart locks are used in residential and the rest in hospitality, enterprise, critical infrastructure etc. The smart lock
