Is a digital signature a signature formed on an electronic document through cryptographic technology?

Electronic Signature (Electronic Signature) is a general term. The accurate full Chinese name should be: electronic signature, which refers to any electronic process indicating acceptance of an agreement or record. Typical common identities of electronic signatures The verification method is to verify the email address, and if you need to increase security, you need to use multi-factor authentication. Electronic signatures should use secure process controls to demonstrate the signing process, and the signed document received by the user should include an audit report of the signing process. If the user sets the use of a handwritten signature pattern or a seal image, there is a problem in electronic signatures that cannot verify whether the handwritten signature or seal image is indeed the signer's signature or the seal of the organization. The parties signing the contract can only either believe the signature image or verify the authenticity of the signature image through other means. This is the disadvantage of electronic signatures.

Digital Signature is a specific type of electronic signature. It can be said to be an improved and more credible electronic signature. The accurate full Chinese name should be: digital signature. Abbreviation: digital signature to distinguish electronic signatures. Digital signature uses a digital certificate to verify the identity of the signer, and binds the signer's identity to the document through a cryptographic algorithm to prove the non-repudiation of the signing behavior. The signed document does not need to contain an audit report of the signing process, and the signer's identity verification is This is done by a Certificate Authority (CA) or Trusted Service Provider (TSP).

Currently, mainstream foreign manufacturers such as DocuSign and Adobe Sign use electronic signatures to achieve online contract signing. Contract signing can be completed only after verifying the email addresses of the signing parties. However, in order to ensure that the signed contract Electronic documents will not be tampered with. After the user signs, the contract document will be digitally signed using the PDF signature certificate of the signature service platform. In other words: the signer does not have his or her own digital certificate for signing documents. According to relevant foreign electronic signature laws, electronic contracts signed electronically are legally valid. According to my country's "Electronic Signature Law", only digital signatures have the same legal effect as handwritten signatures and company seals.

MeSign electronic contract signing service only supports digital signing and does not provide electronic signing, because we believe that only verifying the email address of the contract signer is not enough, especially for online electronic contract signing without meeting in person. . MeSign electronic contract signing service uses digital signing to verify the true identity of each signer, and automatically configures each signer with an Adobe globally trusted and state-secured dual PDF signature certificate for digital signature of contract documents. MeSign document digital signature service only provides digital signatures, verifies the true identity of the document signer, and automatically configures each signer with Adobe's globally trusted and national encryption-compliant dual PDF signature certificates for digital signature of various PDF documents.

MeSign electronic signature services all use Adobe’s globally trusted PDF signature certificate for digital signatures and Adobe’s globally trusted timestamp signatures. Digital signatures support Adobe signature long-term validity (LTV) technology, which is guaranteed The signature of a signed document is permanently valid. All completed electronic contract signings and electronic document signatures use RSA certificates and national secret certificates to achieve dual certificates, double signatures and dual timestamps, ensuring global trust and national secret compliance for the digital signature of every electronic contract and electronic document.
