Abstract

The invention discloses an electronic invoice management method and device, electronic equipment and a computer readable storage medium. The electronic invoice management method comprises the steps ofdetermining a login role of a client; if the login role is an invoicing merchant, acquiring invoicing information, and generating an electronic invoice according to consumption content and the invoicing information, wherein the invoicing information comprises a public key of an invoiced enterprise; generating an encryption key based on the private key of the invoicing merchant and the public keyof the invoiced enterprise, and encrypting the electronic invoice by using the encryption key to obtain an invoice ciphertext; and calculating a hash value of the electronic invoice, and storing the invoice ciphertext and the hash value into a block chain. According to the electronic invoice management method provided by the invention, the encryption key is generated based on the private key of the invoicing merchant and the public key of the invoiced enterprise, and the electronic invoice is encrypted by using the encryption key, and the ciphertext of the electronic invoice is stored in the block chain, so that the security of the electronic invoice is improved.

Description

technical field [0001] The present application relates to the technical field of blockchain, and more specifically, relates to an electronic invoice management method and device, an electronic device, and a computer-readable storage medium. Background technique [0002] The blockchain electronic invoice realizes the seamless connection between consumption scenarios and taxation services. Since the blockchain electronic invoice has the characteristics of complete traceability of the whole process and non-tamperable information, it is consistent with the logic of the invoice, which can effectively avoid false invoices and improve the invoice supervision process. [0003] In related technologies, the hash value of the electronic invoice is uploaded to the chain, and the metadata of the electronic invoice is stored in the central system, which does not fully take advantage of the blockchain's efficient support for data status transfer. If the metadata of the electronic invoice ...
