The official business definition of Document Signatures is the act of verifying a document for its accuracy and authenticity. A document signature typically includes the signer’s name, title or other identifying information as well as a unique identifier, such as a digital image or fingerprint. Document signatures provide legal evidence that a document has been signed by the authorized individual and cannot be repudiated. Document signatures are becoming increasingly important in the world of digital transactions, where they can be used to prove the identity of the signer and provide greater security while improving efficiency.
