This diagram outlines the operational flow of a Handwritten Signature Authentication (HSA) module. The process begins with the user inputting their signature via a signature capture device. This signature is then captured by the HSA module, which communicates with a server or database for both registration and verification purposes. Click to learn more details from this template. This diagram is key for understanding the integration of machine learning models in signature verification systems, which are used to enhance security in various applications.
