Signature matching is a process used to verify the authenticity of a person's signature. It involves comparing a sample signature against a known signature to determine if they match. This technique is commonly used in fields like banking, legal documents, and identity verification. The process typically involves analyzing various features of the signature, such as its shape, size, and the pressure applied during writing. Advanced technology, including software algorithms, can assist in this analysis, making it easier to identify forgeries or confirm genuine signatures.
