Digital Identity Management Systems (DIMS) are now essential tools for enhancing national security, increasing the efficiency of governance, and aiding digital transformation in both rich and developing countries. As governments are moving more and more towards digital public services, financial systems, border checks, and ways to verify citizens, the demand for safe and dependable identity management systems has grown more important. Digital identity systems help to identify citizens correctly, control access, prevent fraud, verify biometrics, secure transactions, and support security operations driven by intelligence. These systems are very important for fighting against terrorism, cybercrime, identity theft, illegal immigration, financial fraud, and cheating in elections. Still, there are problems like worries about privacy, data leaks, weak points in institutions, risks of excluding people, and poor management of cybersecurity that keep threatening how well they work. This paper looks at how digital identity management systems can improve national security, focusing specifically on developing countries. By looking at recent academic research in a thoughtful and detailed way, the study reveals that good digital identity systems can enhance trust in institutions, strengthen security, and improve the delivery of public services. This is especially true when these systems are backed by solid laws, measures to protect privacy, and strong cybersecurity setups. The paper ends by stating that digital identity should be viewed as an important part of the country's security system.
