signature verification

Signature verification is the process of confirming that a signature on a document is genuine and matches the known signature of the person who purportedly signed it. This is often done by comparing the signature in question to a reference signature to check for consistency in style, pressure, and other characteristics. In digital contexts, it may involve cryptographic methods that ensure a signed document hasn't been altered. Signature verification is important for ensuring authenticity in legal, financial, and personal documents, helping to prevent fraud and maintain trust in transactions.
