Article 13 of People's Republic of China (PRC) Electronic Signature Law (revised 20 19) clearly stipulates the conditions that a reliable electronic signature must meet:

(1) Electronic signature data used for electronic signature belongs to the electronic signer;

② When signing, the data produced by electronic signature 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.

In combination with the above provisions, legal and effective electronic signature behavior should meet the requirements of "true identity, true will and tamper resistance".

In addition, the Regulations on the Administration of Electronic Seal promulgated in various places further require the standardization of the electronic seal itself, mainly including that the graphic features of the electronic official seal should be consistent with the physical seal, and the electronic official seal and the electronic private seal should be completely consistent with the real name.
