An electronic contract system refers to an information system that has the functions of the contractor's identity authentication, electronic contract signature, contract storage and call, etc. to realize online electronic contract conclusion and processing, that is, an electronic contract conclusion system.

Therefore, an excellent electronic contract system needs the following functions:

1. Real-name authentication

Real-name authentication is the most important link in the electronic contract system, and the real-name authentication technology can ensure the true identity of the users of electronic signatures and avoid the hidden dangers of fraudulent use and abuse of signatures.

2. Electronic signature management

Electronic signature management functions include a series of operations such as making, authorizing, using, revoking, managing and maintaining electronic signatures.

3. Online editing of documents

The electronic contract system has powerful online editing function, and users can freely edit all kinds of documents, electronic contracts, cooperation agreements, announcements and other contents online.

6. Legal service

In general, the third-party electronic contract system can provide certificate issuing service, providing users with a chain of evidence to prove that the electronic contract signed by users has not been tampered with, effectively preventing repudiation.

To judge whether the electronic signature provided by the third-party electronic contract system is a "reliable electronic signature" as stipulated in the Electronic Signature Law, we can generally judge from three aspects:

1. Reliable electronic signature belongs to the electronic signer;

2. When signing, the digital certificate is controlled by the electronic signer;

3. After signing, relevant technologies such as trusted timestamp should be used to reinforce the data in real time to ensure that the electronic data is not tampered with.

The electronic contract system of our platform has achieved these three points:

①CA certificate issued by CA institutions/eID authentication system of the Ministry of Public Security: adopting the authentication technology of national institutions to ensure the true identity of electronic contract signatories;

② Anti-tampering technology: the original electronic file data is solidified by the internationally accepted hash value technology, and it is easy to identify whether the file has been tampered with;

③ Third-party timing technology: accurately record the signing time.

in addition, we also need to consider the information security of the products and platforms of the third-party electronic contract system. Such as the stability of electronic contract system and the security of data. This involves the qualification of the third-party electronic contract system, and the third-party electronic signature platform with insufficient qualification is insufficient in ensuring the legitimacy of electronic signature. In terms of ensuring the legal effect of electronic signature, the third-party electronic signature platform should have the following qualifications: information security level protection level 3 or higher certification of the Ministry of Public Security, trusted cloud service certification of the Ministry of Industry and Information Technology, and ISO271 certification.
