Difference between Electronic Signature & Digital Signature

Electronic Signature

Electronic signature as the name suggests is a form of signature where a user can sign a document at a click of a mouse, which includes methods such as using a mobile app to capture an image of a handwritten signature. They are not as secure as a digital signature as they aren’t regulated by an authority and totally depend on the vendor. An electronic signature has no encrypted code as that of a digital signature and hence is open to tampering neither are they based on standards.

Digital Signature

Digital Signature is way more secure & holds a higher level of security over electronic signature as they are encrypted with public & private key which is unique for every user. Digital Signature certificate are like a lock on a document if the document is altered after digitally signing it the certificate will become invalid. Digital signatures are always time stamped to keep a track of the date & time of the issuance.

Digital signature holds up in a court of law as compared to an electronic signature which is a mere image of your original signature. One of the major factors to consider digital signature is that they become an intrinsic part of the document hence a legal document such as legal tender or contracts need to be tamper proof in-order to maintain the authenticity.

The process of digitally signing a document includes creation of hash of the document content upon which the signatories certificate is then used to encrypt the hash. This mixture of hashing and encryption creates an intrinsic connection between the document and the signatory.
