The digital representation is signed with the registrant's private encryption key in the terminal (1) and transmitted to a certificate authority (25) through a communication network (23). The registrant's identity is verified at a remote registration terminal (43). After identity verification, the certificate authority forms the certificate by encrypting the digital signature with the certificate authority's own encrypting key in the registration process (24). The certificate is also held in a publicly available directory (4). The document and the certificate are then transmitted to a receiving terminal (83). If the sending party denies sending the document, the biological feature can be extracted from the certificate and directly compared with the actual biological feature of the sending party in the validation process (26).,下面是DIGITAL SIGNATURE PROVIDING NON-REPUDIATION BASED ON BIOLOGICAL INDICIA专利的具体信息内容。
