But the size, style, resolution and even color of the electronic official seal are just a visual experience. In order to have real legal effect, the electronic official seal should meet the following conditions: locking the true identity of the signing subject, effectively preventing document tampering and accurately recording the signing time.
We are considering whether we can bear the legal effect of the official seal. According to Article 13 of the Electronic Signature Law, a reliable electronic signature shall meet the following requirements:
(1) When electronic signature production data is used for electronic signature, it belongs exclusively to 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 electronic official seal of our platform has achieved the following three points at the same time:
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 signing subject of our platform;
(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.
Therefore, the electronic contract signed with the electronic official seal of our platform has the same legal effect as the paper contract.
