Confirmation method and system of electronic file

Abstract

The invention relates to a confirmation method of an electronic file, which comprises the steps that a server and a mobile terminal transmit the electronic file for consumption back and forth, and the server identifies the data file to confirm authenticity of the data file for the consumption. The invention further discloses a validation system of the electronic file, which comprises a server and a first mobile terminal, wherein the server is used for transmitting the electronic file for the consumption to the first mobile terminal; the first mobile terminal returns the electronic file for the consumption to the server; and the server judges the authenticity of the received electronic file for the consumption and transmits a judgment result to the first mobile terminal. The method and the system change the traditional consumption model, and allow a merchant to achieve generation and instant verification of the electronic file for the consumption and carry out instant consumption via a mobile terminal of a user or a mobile terminal of the merchant under the condition that the merchant has no sales terminal.

Problems solved by technology

[0003] The existing technology only involves the generation process and complicated verification process of electronic receipts.
