Abstract

A terminal implementing a method for generating a two-dimensional code may be configured to obtain original document information comprised in an original document information; generate a first summary report based on the original document information; encrypt the first summary report into a digital signature of the original document information; and generate a two-dimensional code based on the original document information and the digital signature. A terminal implementing a method for verifying a document may be configured to obtain a two-dimensional code encrypted from an original document that comprises original document information and a digital signature comprising a first summary report corresponding to the original document information; retrieve from the two-dimensional code the original document information and the digital signature; verify the two-dimensional code according to the original document information and the digital signature; and determine the two-dimensional code to be authentic when the verification is successful.

First claim

What is claimed is:

1 . A terminal for verifying the authenticity of a document, comprising:
a processor-readable storage medium comprising a set of instructions for verifying a document; and a processor in communication with the storage medium configured to execute the set of instructions to: obtain a two-dimensional code encrypted from an original document that comprises original document information and a digital signature that includes a first summary report corresponding to the original document information; retrieve from the two-dimensional code the original document information and the digital signature; verify the two-dimensional code according to the original document information and the digital signature; and determine the two-dimensional code to be authentic when the verification is successful.

2 . The verifying terminal device according to claim 1 , wherein to verify the two-dimensional code the processor is further configured to execute the set of instructions to:
decrypt the digital signature to obtain the first summary report; generate a second summary report corresponding to the original document information; and determine the verification of the two-dimensional code to be successful when the first summary report matches the second summary report.

3 . The verifying terminal device according to claim 1 , wherein to verify the two-dimensional code the processor is further configured to execute the set of instructions to:
obtain a verification message according to the original document information; send the verification message to a verification server; and determine the verification of the two-dimensional code to be successful when receiving a successful verification message from the verification server that information saved therein matches the verification message.

4 . The verifying terminal device according to claim 3 , wherein the verification message comprises at least one of document content of the original document and a link address associated with the original document.

5 . The verifying terminal device according to claim 4 , wherein when the original document information comprises the link address, the processor is further configured to execute the set of instructions to:
send a request for obtaining the document content to a server according to the link address; receive the document content from server, and take the document content or both of the document content and the link address as the verification message.

6 . The verifying terminal device according to claim 4 , wherein:
when the two-dimensional code is a receipt document associated with a transaction between payer and payee, the document content comprises a receipt date, a receipt reason, information of the payee, information of the payer, and an amount of money in the transaction; when the two-dimensional code is a payment document of a transaction between payer and payee, the document content comprises a payment date, a payment reason, information of the payee, information of the payer, and a payment amount of the transaction; when the two-dimensional code is a transfer document of a transfer between a transferor and a transferee, the document content comprises a transfer date, information of the transferor, information of the transferee, a transfer amount, and information of a transfer organization associated with the transfer; when the two-dimensional code is a delivery receipt associated with a transaction between a deliverer and a recipient, the document content comprises a delivery date, a name of goods to be delivered, information of the deliverer, information of the recipient, and an amount of the goods to be delivered; when the two-dimensional code is a goods-pick-up document associated with a transaction, the document content comprises a deadline for receiving goods, a name of goods to be picked up, information of a receiver, and an amount of the goods to be picked up; and when the two-dimensional code is a goods-transfer document associated with a transaction between a transferor and a recipient, the document content comprises a transfer date, information of the transferor, information of the recipient, and an amount of goods to be transferred.

7 . A method for verifying a document by a verifying terminal, comprising:
obtaining, by the verifying terminal, a two-dimensional code encrypted from an original document that comprises original document information and a digital signature comprising a first summary report corresponding to the original document information; retrieving from the two-dimensional code the original document information and the digital signature; verifying the two-dimensional code according to the original document information and the digital signature; and determining the two-dimensional code to be authentic when the verification is successful.

8 . The method according to claim 7 , wherein the verifying of the two-dimensional code comprises:
decrypting the digital signature to obtain the first summary report; generating a second summary report corresponding to the original document information; and determining the verification of the two-dimensional code to be successful when the first summary report matches the second summary report.

9 . The method according to claim 7 , wherein the verifying of the two-dimensional code comprises:
obtaining a verification message according to the original document information; sending the verification message to a verification server; and determining the verification of the two-dimensional code to be successful when receiving a successful verification message from the verification server that information saved therein matches the verification message.

10 . The method according to claim 9 , wherein the verification message comprises at least one of document content of the original document and a link address associated with the original document.

11 . The method according to claim 10 , wherein when the original document information comprises the link address, the obtaining of the verification message comprises:
sending a request for obtaining the document content to a server according to the link address; receiving the document content from server; and taking the document content or both of the document content and the link address as the verification message.

12 . The method according to claim 10 , wherein:
when the two-dimensional code is a receipt document associated with a transaction between payer and payee, the document content comprises a receipt date, a receipt reason, information of the payee, information of the payer, and an amount of money in the transaction; when the two-dimensional code is a payment document of a transaction between payer and payee, the document content comprises a payment date, a payment reason, information of the payee, information of the payer, and a payment amount of the transaction; when the two-dimensional code is a transfer document of a transfer between a transferor and a transferee, the document content comprises a transfer date, information of the transferor, information of the transferee, a transfer amount, and information of a transfer organization associated with the transfer; when the two-dimensional code is a delivery receipt associated with a transaction between a deliverer and a recipient, the document content comprises a delivery date, a name of goods to be delivered, information of the deliverer, information of the recipient, and an amount of the goods to be delivered; when the two-dimensional code is a goods-pick-up document associated with a transaction, the document content comprises a deadline for receiv
