Electronic signature refers to the data contained in the data message in electronic form and accompanied by data used to identify the identity of the signer and show that the signer approves its content. Generally speaking, electronic signature is an electronic signature of electronic documents through cryptographic technology, which is not a digital visualization of written signature, but similar to handwritten signature or seal, and can also be said to be an electronic seal. The purpose of electronic signature is to sign the electronic version of Mid-Autumn Festival greeting cards, invitations and construction contracts.
From the definition of electronic signature, we can see two basic functions of electronic signature:
(1) Identify the signer.
(2) Indicate the signatory's approval of the content.
The law fully considers the technical neutrality when defining electronic signature, and extracts the provisions on electronic signature according to the basic functions of signature. It is considered that all electronic technical means that meet the basic functions of signature can be considered as electronic signature.
From the definition of electronic signature and digital signature, we can see the difference between them: electronic signature is put forward from the legal point of view and is technology-neutral, and any electronic technical means that meets the basic functions of signature can be called electronic signature; Digital signature is put forward from a technical point of view, which requires the use of cryptographic technology. The main purpose is to confirm the source and integrity of the data unit.
Electronic signature is a broad concept, and digital signature can be regarded as a way to realize electronic signature, which provides higher functions than the basic requirements of electronic signature.
