It is impossible to verify the authenticity by printing. This electronic signature tool should be directly used for the verification of electronic data documents.

Of course, printing can still make a basic preliminary judgment, or you can identify some particularly obvious fake seals. Such as the checkmark after signing.

origin

Long before the promulgation and implementation of China's Electronic Signature Law, electronic seals appeared. In the middle and late 1990s, as the traditional office mode gradually changed to the information office mode, the circulation form of paper documents also changed to electronic documents. In order to ensure the validity of electronic documents and make them have the same visual effect of public trust as traditional paper documents, the concept of electronic seal is put forward.

Before the formal implementation of the electronic signature law in China on April 1 2005, the electronic seal had not been widely recognized and applied, so there were not many companies engaged in the research of electronic seal earlier in China. After the promulgation and implementation of Electronic Signature Law, the research and application of electronic seal technology and its products have developed rapidly.
