摘要

PURPOSE: A spam mail blocking security mail system for sending/receiving emails through a dynamic signature authentication server is provided to enhance business efficiency and promote the EC(Electronic Commerce) through the email by fundamentally blocking sending/reception of illegal spam mails with use of a dynamic signature authentication technology. CONSTITUTION: A sender has to register a written signature and sends the email by installing a signature authentication plug-in module to a mail browser. A receiver installs the signature authentication plug-in module to the mail browser. In a state receiving authentication from a signature authentication server, the sender sends the email as an encrypted file attaching a dynamic signature. The receiver checks authentication by sending dynamic signature data attached to the received email and ID information of the sender to the signature authentication server, and classifies the email into a normal email in case of the verified email or into the spam mail in the case of the unverified email.
