Electronic seal technology is to simulate the traditional physical seal with advanced digital technology, and its management and use methods are in line with the habits and experiences of physical seals. The electronic document stamped with its seal has the same appearance, the same effect and similar usage as the paper document stamped with its physical seal.
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 the circulation form of 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.
