1. When electronic signature production data is used for electronic signature, it belongs to the exclusive rights of the electronic signer.
Electronic signature production data refers to the characters, codes and other data used in the process of electronic signature to reliably link the electronic signature with the electronic signer. It is the core data that the electronic signer grasps in the signature process. Only by judging the ownership of electronic signature production data can we determine the identity and accuracy between electronic signature and electronic signer.
Therefore, once the electronic signature production data is occupied by others, the electronic signature generated by relying on the electronic signature production data may be inconsistent with the wishes of the electronic signer and obviously cannot be regarded as a reliable electronic signature.
Two, when signing the electronic signature data is only controlled by the electronic signer.
This regulation is a requirement for who controls the data of electronic signature in the process of electronic signature. The control specified here refers to the control of electronic signature production data based on the free will of the electronic signer.
In the process of electronic signature by an electronic signer, whether the electronic signer carries out the signature by himself or entrusts others to carry out the signature on his behalf, as long as the electronic signer has substantial control, his signature will meet the requirements of this law.
Third, any changes to the electronic signature after signing can be found.
After the signer who adopts digital signature technology signs, the other party can verify whether the data message it receives is sent by the sender and whether the sender's digital signature has been changed through certain technical means. If it can be found that the digital signature of the sender has been changed by others after signing, the signature cannot meet the requirements of this law and cannot be a reliable electronic signature.
Four, after the signing of any changes to the content and form of the message can be found.
An important function of electronic signature is to show that the signer approves the content of data message, and to realize this function, it is necessary to require electronic signature to technically ensure that the message signed by the signer will not be tampered with by others. Otherwise, the electronic signer will realize the electronic signature according to certain technical means, and the signed message will be tampered with by others but cannot be discovered, and the legal disputes arising at this time will not be solved according to this law.
At present, Wang Hua's handwritten electronic signature board in China has realized the concept of signing on paper through electromagnetic pressure sensitive pen. The signature handwriting is unique: it is only controlled by the electronic signer and belongs to the electronic signer, and any changes can be found.
