Thirteenth electronic signatures meet the following conditions at the same time, as reliable:
(1) When the electronic signature production data is used for electronic signature, it belongs to the exclusive rights of 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.
The parties can also choose to use electronic signatures that meet their agreed reliable conditions.
For example, handwritten signature on paper, then making photos with mobile phones and other electronic devices, then hollowing out the background color of paper to form pictures with only signed words, and then using them in electronic documents, such a signature method has no legal effect, and it is impossible to identify who the signer is and under what circumstances by font.
-What is an electronic signature of original handwriting?
Based on biometric identification technology, the signature information is manually input through electronic equipment, and the external form and biometric data of the signature are recorded to ensure that the retained data of the electronic signature can be used for judicial authentication. Like the paper signature, it can play the role of identifying the real identity of the signer based on the principle of trace science and biological characteristics, and is regarded as the original of handwritten electronic signature.
-Technical characteristics
Input signature information through electronic equipment, collect multi-dimensional behavior characteristic information such as strokes, stroke sequence, stroke pressure, stroke speed, signature time, etc. in the writing process of the signer, and form a data packet. After the collection is completed, the signature font has the function of handwriting recognition. The biometric information of the signature is extracted by an algorithm, and the causes of the restored handwriting are traced by the principle of graphology, and the handwriting trends and writing habits are analyzed, and intelligent comparison is made, which can effectively identify whether the signature is my own.
-Technical advantages
While retaining the traditional signature habit, the handwritten original handwriting electronic signature records more characteristic information than the paper signature, and at the same time, it uses technologies such as state secret encryption and blockchain storage to ensure the tamper resistance and non-repudiation of the electronic signature. It is a reliable electronic signature method with judicial effect.
