Description

Method and system for realizing paperless receipt based on webpage
Technical Field
The invention relates to a transmission encryption method of an electronic certificate, in particular to a method and a system for realizing paperless receipt based on a webpage.
Background
With the development of e-government affairs and e-commerce, more and more information is interacted through Web pages, such as online contracts, online examination and approval, and the Web pages embody the authenticity and the effectiveness by means of stamping electronic seals. At present, a way of embedding a stamp image into a Web page is usually adopted for displaying a Web page stamp, when a user opens the Web page by using a browser, the stamp image is already embedded into the Web page, and when the stamp image is clicked, the stamp image can be saved, but the saved stamp image has the problem of being illegally used. Therefore, how to avoid the illegal acquisition and use of the seal of the Web page becomes a problem to be solved urgently.
In the prior art, for example, chinese patent with publication number CN108038388B discloses a method for implementing a Web page seal, a client and a server, wherein the method comprises the following steps: the method comprises the steps of drawing an electronic seal on an embedded window of a Web page according to data of the electronic seal, signing the Web page, generating a digital signature, and submitting data of the electronic seal and the digital signature to a server, wherein the server is used for providing the Web page, so that the electronic seal is drawn on the embedded window of the Web page by using the data of the electronic seal, the drawn electronic seal is only a display result of the electronic seal and does not contain the data of the electronic seal or a link of the data of the electronic seal, a user cannot obtain the data of the electronic seal from the embedded window, and the seal of the Web page is effectively prevented from being illegally obtained and used.
Disclosure of Invention
The invention aims to provide a method for realizing paperless receipt based on a webpage aiming at the prior art, which comprises the following steps: the server receives first page receipt authentication request information submitted by a payment end and second page receipt generation request information of a collection end; the second page document generation request information of the collection end contains a document to be verified encrypted by the initial key; the document to be verified contains payment seal data information, collection seal data information and document information; the server verifies a second page receipt generation request and a first page receipt authentication request of the receiving end; the first page document authentication request contains payment seal data and document information encrypted by an initial key; after the authentication request information of the first page bill and the generation request information of the second page bill of the collection end are verified, the server draws an electronic receipt data information positive copy and an electronic receipt data information copy with authentication data seal; the server sends the electronic receipt information copy to the collection end and sends the electronic receipt data information original copy to the payment end. And the cryptograph submission of the payment end and the collection end is isolated by the server, so that the sniffing attack can be reduced. The initial key of the collection end is independently distributed to the payment end and the server for verification, and the server respectively uses the initial key to decrypt the first page document authentication request and the second page document generation request during verification, so that the independence is high, the verification comparison is lost once the initial keys are not matched, and the transmission safety is improved by combining the initial key and the second page document authentication request. On the other hand, the encryption and decryption model further improves the security of ciphertext attack.
The payment end sends a first page access request to the collection end, and then the collection end transmits a first page containing an initial key to the payment end; and the receiving end sends the initial key corresponding to the first page to the server. The data information related to the corresponding relation between the first page and the initial key comprises time information, payment end identity information and physical address information of the first page. By using the associated data information as a row vector QkThe seed information is provided to assist the receiving end in generating the initial key. For example, a row vector QkMay be a random number conversion acquisition associated with time information of the first page, and transmits the initial key to the payer and the server in steps S20 and S21, respectively, since the initial key is a randomly generated row vector QkAnd the row vector is in corresponding relation with the first page, so that the uniqueness is realized on a large space-time scale. In the prior art, how to generate the time-dependent random numbers is not described in detail herein.
And after receiving the information of the first page containing the initial key, the payment terminal encrypts a payment seal of the payment terminal by using the initial key to generate initial payment seal data and compiles the initial payment seal data into a first bill generation request. The initial key is used and transmitted in the technical scheme, the calculation power occupied by application is less than that of the prior art, the calculation power consumption can be reduced, the balance calculation power is given to chaotic operation, and the efficiency of applying the encryption calculation power is improved.
The first document generation request contains payment seal data and document information encrypted by an initial key. Encryption is used in the first document generation request, certain calculation power of a payment end is occupied, meanwhile, data of the second page document generation request are derived from the calculation power of a collection end, which is occupied by the data of the superposed payment seal on the data of the S50 initial payment seal, and the calculation power of a server end is occupied in the S70 verification step, so that the calculation power is relatively balanced. Under the condition that the load of the receipt system is high, the computational stress of the server is increased, and the management and capacity expansion are relatively easy.
