An electronic contract is an agreement between two or more parties to conclude, change and terminate the civil rights and obligations of property through electronic information networks. Electronic contract is a legally recognized form of contract signing. An electronic contract loaded with reliable electronic signature, third-party timing service and tamper-proof technology has the same legal effect as a paper contract.

Electronic signature refers to the data contained in the data message in electronic form and accompanied by data used to identify the identity of the signer and show that the signer approves its content. Electronic signature is not a digital image of written signature, but an electronic code representing the true identity of an individual or enterprise. Article 14 of the Electronic Signature Law stipulates that a reliable electronic signature has the same legal effect as a handwritten signature or seal.
