Detailed explanation-1: -Definition(s): The process of using a digital signature algorithm and a public key to verify a digital signature on data.
Detailed explanation-2: -What Does Signature Verification Mean? Signature verification is a technique used by banks, intelligence agencies and high-profile institutions to validate the identity of an individual. Signature verification is often used to compare signatures in bank offices and other branch capture.
Detailed explanation-3: -There are two main types of signature identification and verification systems: Offline (static) systems and Online (dynamic) systems. In the offline systems, signature is captured or scanned from a document such as bank checks then the system must read and extract features from the image of the signature.
Detailed explanation-4: -DSA stands for Digital Signature Algorithm. It is a cryptographic algorithm used to generate digital signatures, authenticate the sender of a digital message, and prevent message tampering. DSA works by having two keys: a private key owned by the sender and a public key held by the receiver.
