Taking us as an example, some third-party electronic signature platforms have the following technologies, which can lock the real identity of the signature subject, effectively prevent file tampering and accurately record the signature time:
Face biometrics, bank card elements and other technical means to carry out real-name authentication to ensure that the electronic signature is exclusive to me.
Encrypt login, reserve the random dynamic password of mobile phone, and ensure that the signature behavior is controlled by the signer.
The national authority issues the CA certificate, and ensures the uniqueness of the fingerprint of the certificate, which makes the tampering invalid and can identify the authenticity and validity of the signature.
The authenticity of the contract can be verified by converting the contract file into a tamper-proof PDF and stamping it with the time stamp of the National Time Service Center.
In addition to these technical guarantees, the Electronic Signature Law stipulates that
Article 13
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
A reliable electronic signature has the same legal effect as a handwritten signature or seal.
