Enhancing two-factor authentication: Integrating face recognition with a dynamically generated token mechanism for secure transactions.

Today, image processing plays a vital role in authentication and other security purposes. Most smartphone users now rely on face recognition as one of the key mechanisms for mobile security. Additionally, many organizations use face recognition systems for authentication and attendance purposes. In such systems, users are required to use a specific security mechanism for approval and related activities. In the proposed paper, instead of relying solely on physical presence, static image data is captured and supplemented by a one-time generated token to enhance the authentication process. This method allows users to present a static digital image in front of the authorization system, after which they enter the one-time generated token as an additional layer of security. The proposed system eliminates the need for constant physical presence while improving two-factor authentication—combining face recognition with a dynamically generated token. As a result, the user's presence is verified, and the overall efficiency of the process is enhanced. The proposed procedure demonstrates that this technique yields more effective results compared to existing one-time authentication methods.
