Natural phenomena such as floods, storms, volcanic eruptions, earthquakes, landslides have affected our planet in an unpredictable way. However, these phenomena are merely classified as a hazard when they may affect people and the things they value (Cutter, 2005). The involvement of many agencies and the public is important in planning for disaster relief, in rescuing victims, and in managing the event. A lot of individuals are deprived of help due to poor coordination, late assistance and uneven distribution of food, water, medical assistance, clothes, and vehicles. The need for a proper disaster relief plan is crucial to overcome these challenges. On the other hand, identity theft is one of the most bizarre and rapidly growing crimes present in the world. Identity thieves are active more than ever as the e-commerce trading keeps on growing. Earlier the thieves used to buy pieces and parts of someone's personal identification information but now they could have hold of everything. Similarly there has been an increase in illegal immigration, smuggling of weapons and terrorist activities noticed in last 2 decades in the United States. This study focuses on the current condition of disaster management, identity theft, border security and controlling the misuse of weapon of mass destruction. It proposes the use of advanced technological methods like Blockchain to overcome the loss of time and cost to provide a quick response to the victims and to provide secure ways to store personal identification information and better national security. The study helps to understand how better disaster management and national security can be achieved by using various use cases and implementation models. By implementing these models, the border security can be improved and proper handling of weapons of mass destruction can also take place.
