Extended data:

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 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.

Electronic signature is data in electronic form, which is associated with data message (electronic document, electronic information) to identify the identity of the signer and show that the signer approves the content of the data message.

Electronic signature is an online identity authentication system based on international PKI standard, and digital certificate is equivalent to online identity card. Through the third-party authoritative authentication of digital signature, it can effectively authenticate online identity, help each subject identify each other's identity and show their own identity, and has the functions of authenticity and anti-denial. Different from physical ID cards, digital certificates also have the characteristics of security, confidentiality and tamper resistance, which can effectively protect and securely transmit information transmitted by enterprises on the Internet.
