Most people think a digital signature is the application of an electronic representation of a signature to a document. In fact, a digital signature involves a formal process of utilizing a digital certificate issued by a Certificate Authority (e.g. VeriSign, GoDaddy, Comodo) that uses public key cryptography to create a unique representation of a message or document. SmartSign incorporates both electronic signatures and digital signatures to simplify the capture across multiple channels such as web, mobile, point of sale, and others.
