Electronic Invoice Authenticity Verifying Scheme Based on Signature Recognition

Abstract

With the rapid development of network and information technology, paperless and electronics have become the development trend of today's economic life. As a consumption certificate, e-invoice has become more and more demanding in e-commerce. The existing electronic invoice verification method only judges whether the electronic invoice has passed the verification by verifying the authenticity of the digital signature of the seller. Although the verification result has certain reference value, it is assumed that the electronic invoice does not authorize by the tax authority, because the verification process will not verify the signature of the tax authority, which cannot be detected as an illegal behavior. This verification method cannot guarantee the complete legality and authenticity of the electronic invoice. Aimed at the above problems, this paper designs a digital signature-based electronic invoice authenticity verifying scheme. By verifying the legality of the signature of the seller and tax authority, and the truth of the trading information, it can ensure the authenticity of the electronic invoice passed.
