Of course, these requirements are not the core issue to judge whether the electronic seal has legal effect. Electronic seal is an application of electronic signature. According to the provisions of the Electronic Signature Law, an electronic contract that locks the true identity of the signer, effectively prevents document tampering and accurately records the signature time is legally recognized.
Article 13 of the Electronic Signature Law stipulates that an electronic signature shall be regarded as reliable if it meets the following conditions:
(1) When the electronic signature production data is used for electronic signature, it belongs to the exclusive rights of the electronic signer;
(2) When signing, the electronic signature production data is only controlled by the electronic signer;
(3) Any changes to the electronic signature after signature can be found;
(4) Any changes to the content and form of the data message after signature can be found.
The parties can also choose to use electronic signatures that meet their agreed reliable conditions.
Article 14 of the Electronic Signature Law stipulates that a reliable electronic signature has the same legal effect as a handwritten signature or seal.
So the legal effect of electronic seal is guaranteed by technical means, and we can do it-
① CA certificate issued by the CA organization /eID authentication system of the Ministry of Public Security: adopting the national organization authentication technology to ensure the true identity of the electronic contract signatory;
(2) Anti-tampering technology: the original electronic file data is solidified by using the internationally accepted hash value technology, which is easy to identify whether the file has been tampered with;
Third-party timing technology: accurately record the signing time.
