An electronic signature exists in electronic form, is attached to an electronic document and is logically related to it. It can be used to identify the identity of the signer of the electronic document and indicate the signer's agreement with the content of the electronic document. Electronic signature solves the problem of signing and sealing electronic documents. It is used to identify the identity of the signer of electronic documents, ensure the integrity of the document, and ensure the authenticity, reliability and non-repudiation of the document.

Usually electronic signatures are also called electronic signatures. The seal is the visual embodiment of the electronic signature. The explicit existence of the seal is to be close to the user's habits. What is truly legally effective is the electronic signature, which is electronically processed through the hash value of the signature content (a document, a piece of code, a picture, etc.) The signature obtains the signature value and combines it with the seal image and the original signature file to form a signed structured document, that is, a signed document after electronic signature is obtained.
