The invention provides a network online
invoice making method. Based on internet and
computer technology, the method provides comprehensive real-
time management services for the links of purchase, making, use, inquiry,
data application and the like of an
invoice of a taxpayer. The method comprises the following steps of: realizing the
authentication of a taxpayer identity by using a digital
certificate; ensuring the
transmission security of
invoice data on
the internet by using an HTTPS
encryption protocol; establishing a security channel between a user and a backstage
server; realizing bidirectional
data security transmission by
encryption technology; generating an invoice security code used for verifying the authenticity and the completeness of invoice face value information by invoice anti-counterfeiting technology. An online invoice making key is a medium for the digital
certificate, a face value anti-counterfeiting
algorithm and secure storage, and finishes data
encryption,
data decryption,
digital signature,
data verification and the like. Therefore, the problems of false invoice, writing false invoice, making an invoice excluding income, filling and making non-standard invoice,
declaration data
distortion and the like are solved fundamentally.
