What is really effective is the reliable electronic signature technology. Handwritten signature is only a visual effect, so with the help of reliable electronic signature technology and the third-party electronic contract conclusion platform, the signed contract can replace the paper contract and has the same legal effect and document effect.

1. Confirm the true identity of the signer.

① Third-party electronic signature platform carries out real-name authentication.

After the user registers the platform account, the platform will require the user to carry out real-name authentication, and the electronic contract can only be signed after the authentication is passed. In real-name authentication, individual users need to submit personal identity information, and enterprise users need to submit enterprise information. The third-party electronic signature platform will access the personal identity authentication system of the Ministry of Public Security and the enterprise information system of the State Administration for Industry and Commerce to check the user identity information and ensure that the user identity will not be impersonated.

② Digital certificate issued by CA organization.

CA, the certification authority, is a trusted third party in e-commerce transactions. When the user passes the real-name authentication of the third-party electronic signature platform, he can obtain the digital certificate issued by the CA organization cooperating with the third-party electronic signature platform as the basis of the user's online identity certificate. Certificates are based on digital signature technology, so they cannot be forged or tampered with.

2. Create an exclusive electronic signature

After real-name authentication, users can start to create their own exclusive electronic signatures, which will be stored in the form of data messages on the third-party electronic signature platform.
