Electronic official seal is an application of electronic signature technology. It is not simply to visualize the traditional official seal electronically, but to use technology to achieve legal effect. The electronic official seal with legal effect can eliminate the radish seal.

To produce an electronic official seal with legal effect, the general third-party signature platform needs the following technologies:

1.？ Authoritative authentication system: adopting the authentication technology of national institutions to ensure the true identity of the subject of electronic signature;

2.？ Anti-tampering technology: the original electronic file data is solidified by using the international universal hash value technology, which is easy to identify whether the file has been tampered with;

3.？ Third-party timing technology: accurately record time.

One of the advantages of an effective electronic official seal is that it can put an end to the "radish stamp", because the electronic official seal can be authenticated by a third-party authority in the form of digital signature, effectively carry out online identity authentication, help each subject identify the identity of the other party, show their identity, and avoid abuse and forgery by others.

An effective electronic official seal can not only prevent forgery, but also prevent loss. Only authorized users can use it, which greatly avoids the risk of abuse and misuse.
