Digital Signature vs Electronic Signature

Electronic signatures, commonly referred to as e-signatures, are a broad set of solutions that use an electronic process for accepting a document or transaction with a signature. As documents and communication are increasingly paperless, businesses and consumers worldwide have embraced the speed and convenience of these types of signatures. But there are many different types of electronic signatures, each allowing users to sign documents digitally and offering some degree of identity authentication.

Digital signatures are one of those electronic signature technologies and are the most secure type available. Digital signatures use PKI certificates from a Certificate Authority (CA), a type of Trust Service Provider, to ensure identity authentication and document integrity by encrypted binding of the signature to the document. Other, less secure e-signature types may use common electronic authentication methods to verify the signer’s identity, such as an email address, a corporate username/ID, or a phone number or PIN.


How Do Digital Signatures Work?



Digital signatures use public key infrastructure (PKI), which is considered the top most standard for digital identity authentication and encryption. PKI relies upon the use of two related keys, a public key and a private key, that together create a key pair to encrypt and decrypt a message using strong public key cryptography algorithms. Using both public and private keys that are generated using a mathematical algorithm to provide the signer with their own digital identity, a digital signature is generated and encrypted using that signer’s private key, and also a timestamp of when the document was signed using the key.

The process to create a digital signature is easy and straightforward for the average user and for enterprises to adopt. You first need a digital signing certificate, which can be acquired through a trusted Certificate Authority like Capricorn. After downloading and installing the certificate, you simply use the digital signing function of the appropriate document platform or application. For example, most email applications provide a “Digitally Sign” button to digitally sign your emails. 


Digital signature technology requires all involved parties to trust that the individual creating the signature has been able to keep their own private key secret. If someone else has access to the signer's private key, that party could create fraudulent digital signatures in the name of the private key holder.

What happens if either the sender or receiver change the file after it has been digitally signed? As the hash value for the file is unique, any change to the file creates a different hash value. As a result, when the receiver’s computer compares the hash to validate the integrity of the data, the difference in the hash values would reveal the file had been altered. Thus, the digital signature would be shown as invalid.

 Why Are They Important?

As more business is conducted online, agreements and transactions that were once signed on paper and delivered physically are now being replaced with fully digital documents and workflows. whenever valuable or sensitive data is shared, malicious person who want to steal or manipulate that information for their own gain are ever-present. Businesses must be able to verify and authenticate that these critical business documents, data, and communications are trusted and delivered securely to reduce the risk of document tampering by malicious parties.

In addition, the signature is portable as it is incorporated in the file itself, wherever it is transmitted and on whatever device. Digitally signed documents are also easy to control and keep track of by providing the status of all documents, identifying whether or not they’ve been signed, and viewing an audit trail.
