The concept of digital identity has gained prominence in the digital interconnected world, defined by ubiquitous online interactions and transactions. Digital identity verification has become essential, facilitating effortless access to numerous services. Nonetheless, it poses considerable security concerns, including inadequate encryption standards, susceptibility to identity theft and fraud, low user awareness, and dependencies on obsolete verification mechanisms, among others. This research provides an innovative security solution for digital identity verification using an AES-encrypted smart national identification card combined with a two-factor OTP authentication mechanism. AES encryption offers formidable security by encoding sensitive data, rendering it exceedingly challenging for unauthorized individuals to get access. When integrated with intelligent NID, it guarantees that only authorized users can authenticate their identity. Two factor OTP enhances security by necessitating a secondary verification method, delivered to a user’s mobile device. This combination markedly diminishes the danger of identity theft, unauthorized access, and data breaches, thereby safeguarding users personal and sensitive information in the digital realm. This strategy enhances user confidence in digital services while facilitating secure and dependable access to vital internet platforms, hence fostering digital inclusion in developing nations.
