The Electronic Signature Law clearly defines a reliable electronic signature: "An electronic signature is considered reliable if it meets the following conditions at the same time:

1) When the electronic signature production data is used for electronic signature, it belongs exclusively to 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 signing can be found;

4) Any changes to the content and form of the data message after signature can be found. "

The reason why the Electronic Signature Law emphasizes "reliable electronic signatures" shows that there are a large number of unreliable electronic signatures in reality. Therefore, only those who meet the above four conditions can be called reliable electronic signatures!

"Reliable electronic signature" is not only a technical term, but also a legal term.
