How are digital signatures verified?
An important element in this process is an intermediary called a “certification authority.” It is the certification authority’s job to establish the link between the signer and the keys used to create the digital signature. In essence, the certification authority reviews the signer’s identification documents, such as a driver’s license or passport, and then certifies that the person who is using the keys is actually the person they claim to be. Anyone who wishes to verify a digital signature may then rely on the certification authority’s identification of the person instead of having to personally review the signer’s identification documents. In this way, digital signatures work much in the same way as signature cards kept on file by banks which are taken out when needed to verify authenticity. The digital signature is often invisibly attached to a submitted document in the form of an encrypted “certificate.” This “certificate” would look like a scrambled series of letters and numbers
