What is a Digital Signature?

Digital signatures (standard electronic signatures) take the concept of traditional paper-based signing and turn it into an electronic “fingerprint.” This “fingerprint,” or coded message, is unique to both the document and the signer and binds both of them together.

Digital signature ensures the authenticity of the signer. Any changes made to the document after it is signed – invalidates the signature, thereby protecting against signature forgery and information tampering.

Digital signatures sustain signer authenticity, accountability, data integrity and non-repudiation of documents and transactions.
