Article 14 of the Electronic Signature Law stipulates that a reliable electronic signature has the same legal effect as a handwritten signature. At the same time, article 13 stipulates that an electronic signature can only be regarded as reliable if it meets the following conditions:
(1) When 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 signature can be found;
(4) Any changes to the content and form of the data message after signature can be found.
Principle of electronic signature: Following the above explanation of electronic signature, we can simply understand that a digital certificate is the "electronic identity" of "I am me" under the network environment, and this "electronic identity" needs to be managed by a special organization, namely CA organization.
When users sign contracts online with electronic signatures, CA institutions verify the authenticity and validity of the signer's identity information through a series of technical means and specific steps, and then issue digital certificates to the parties and authorize them to sign contracts. This is the process of CA authentication.
(Note: Because the interpretation of electronic signature involves many technical principles, it is not applicable to users without technical background, so I will not repeat it here for the time being. Friends in need can contact the author. )
The function of electronic signature can be embodied as follows: through the above-mentioned authentication process, after the electronic contract is signed, the parties can quickly identify the identity of the signer, the signed content and other important information by only identifying the electronic signature, thus avoiding illegal acts such as stealing, embezzling and tampering with the contract.
Application scenario of electronic signature: At present, electronic signature continues to be popular and has been applied to many industries such as finance, e-commerce, law, personnel, medical care, manufacturing, tourism, education, real estate, building materials and so on. , making the signature scenes of various industries electronic, thus speeding up the cost reduction and controlling the hidden dangers caused by illegal use of seals.
