[0051] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present invention.

[0052] In order to make the purpose, technical solutions and advantages of the present invention more clear, specific embodiments will be described below in conjunction with the accompanying drawings.

[0053] Please refer to Figure 1 , Figure 1 A flowchart of an electronic document storage method provided by an embodiment of the present invention includes:

[0054] S101: Receive a document storage request from a user, where the document storage request includes an original electronic document.

[0055] The execution subject of the present method may be a terminal device or a server. In the present embodiment, the document evidence request may be directly input to the execution subject by the user through an input device, or may be sent to the execution subject by the user through a user terminal, which is not limited here.

[0056] In this embodiment, the document deposit request may also include the requester ID, the identifier of the original electronic document, other attribute information of the original electronic document, etc.

[0057] S102: Call the storage interface of the target blockchain to store the original electronic document once, and obtain a storage result of the original electronic document.

[0058] In this embodiment, the content of the primary storage includes but is not limited to the document content of the original electronic document, the hash value corresponding to the original electronic document, etc. The primary storage result of the original electronic document includes but is not limited to the hash value of the original electronic document, the storage transaction ID, the hash value / height / time of the transaction packaging block, etc.

[0059] S103: Writing the primary evidence storage result back to the original electronic document to obtain a converted document corresponding to the original electronic document.

[0060] In this embodiment, the primary storage result can be written back to the preset position of the original electronic document to obtain a converted document corresponding to the original electronic document. The preset position includes but is not limited to the starting position of the original electronic document, the ending position of the original electronic document, and other blank areas of the original electronic document.

[0061] In a possible implementation, a storage result is written back to the original electronic document to obtain a conversion document corresponding to the original electronic document, including:

[0062] Convert the result of a storage to generate readable information.

[0063] The readable information is written back to the original electronic document to obtain a converted document corresponding to the original electronic document.

[0064] The readable information may be a QR code or a character string.

[0065] S104: Call the target blockchain’s evidence storage interface to perform secondary evidence storage on the converted document.

[0066] In this embodiment, after the converted document is secondary stored, the secondary storage result may be returned to the user who submitted the document storage request, or the secondary storage result may be directly discarded.

[0067] In a possible implementation, if a document download request submitted by a user is received, the converted document corresponding to the document download request is returned to the user who submitted the document download request. The document download request includes a request document identifier, and the query interface of the target blockchain can be called according to the request document identifier to find the corresponding converted document and return it to the user who submitted the document download request.

[0068] From the above, it can be concluded that, different from the solution in the prior art that electronic documents are stored in the form of backup in one's own organization or on a rented server, the embodiment of the present invention realizes the storage of electronic documents based on blockchain. Blockchain is a new technical solution that integrates multiple technologies such as distributed network, encryption technology, and smart contracts. It is an important part of the new generation of information technology. The embodiment of the present invention utilizes the characteristics of "decentralization and tamper-proof" of blockchain, which not only solves the credibility problem of electronic document storage in the prior art, but also supports users to retrieve, view, and download blockchain electronic documents anytime and anywhere, thereby improving the efficiency of obtaining electronic documents. On this basis, the embodiment of the present invention also provides a secondary storage solution to further improve the credibility of electronic document storage. Moreover, based on the secondary storage, the embodiment of the present invention can distribute converted documents (rather than original electronic documents) to users when they obtain documents. Users can quickly verify and trace electronic documents based on the primary storage results in the converted documents, effectively improving the efficiency of electronic document verification.

[0069] In a first possible implementation, the electronic document storage method further includes:

[0070] A document verification request is received from a user via a smart terminal. The document verification request includes a one-time evidence storage result held by the user. The one-time evidence storage result held by the user is obtained by scanning a code of a converted document held by the user via the smart terminal.

[0071] The converted document held by the user is verified based on the result of a primary evidence storage held by the user.

[0072] Based on the above embodiment, this embodiment also provides a method for verifying the authenticity of an electronic document after it is stored. A user can read the converted document he holds through a smart terminal to determine the primary storage result of the converted document he holds. Then, the user can make a document verification request based on the primary storage result of the converted document he holds, so as to verify the converted document he holds.

[0073] In a possible specific implementation, the user can scan the readable information (which can be a QR code or a string) in the converted document held by the user through a smart terminal to obtain the one-time evidence result of the converted document held by the user (including but not limited to information such as block height / block hash value / transaction ID). Then the user makes a document verification request through a blockchain browser (the terminal where it is located corresponds to the execution subject of the embodiment of the present invention), queries the corresponding blocks and transactions in the one-time evidence information, checks whether there is an evidence of the converted document held by the user in the transaction (document hash value or all contents), and checks whether the transaction package block height and time are consistent with the one-time evidence result of the converted document held by the user. If they are consistent, it proves that the original electronic document of the converted document has been evidenced, which indicates that the converted document held by the user has passed the verification (that is, the one-time evidence result input by the user can be used to determine whether the converted document held by the user has passed the verification). This method is based on the one-time evidence result verification and can be applied to the verification of electronic documents / paper documents. The characteristic is to scan the readable information in the converted document.

[0074] Among them, after confirming that the converted document held by the user has passed the authentication, the corresponding original electronic document can also be returned to the user.

[0075] Among them, the corresponding block information and transaction information can also be directly returned to the user based on the one-time evidence storage result held by the user, and the user can perform manual comparison to realize document verification, which is not limited here.

[0076] In a second possible implementation, the electronic document storage method further includes:

[0077] A document verification request sent by a user through a web page is received, where the document verification request includes a converted document submitted by the user through the web page.

[0078] Call the verification interface of the target blockchain to verify the conversion document submitted by the user.

[0079] If the converted document submitted by the user passes the first verification, the first evidence result in the converted document submitted by the user is extracted, and the converted document submitted by the user is verified for a second time based on the first evidence result in the converted document submitted by the user.

[0080] Based on the above embodiments, this embodiment also provides a method for verifying the authenticity of an electronic document after it is stored, that is, the user can directly submit the converted document he holds on the document verification web page, and the system (corresponding to the execution entity in this solution) will automatically perform a second verification on it.

[0081] In a possible specific implementation, the user can submit the converted document held by the user to the system through the document verification web page. The system calls the verification interface of the target blockchain to verify the converted document submitted by the user, that is, to verify whether the converted document held by the user has been stored. If it has been stored, the first verification is passed (that is, it is confirmed that the converted document is a document that has been stored twice and has not been tampered with). If it has not been stored, it means that the converted document held by the user is a forged document. If the first verification is passed, the first storage result in the converted document submitted by the user is extracted, and the storage information of the first storage result in the converted document submitted by the user is checked to see if it is correct. If it is correct, the second verification is passed (that is, it is confirmed that the corresponding original document is a document that has been stored once), indicating that the converted document held by the user is compliant.

[0082] Among them, in a possible implementation method, calling the verification interface of the target blockchain to verify the conversion document submitted by the user, including:

[0083] Computes the hash value of the transformed document submitted by the user.

[0084] Call the verification interface of the target blockchain to determine whether the hash value has been stored in the target blockchain.

[0085] If the hash value has been stored in the target blockchain, the converted document submitted by the user will be verified once.

[0086] In a third possible implementation, the electronic document storage method further includes:

[0087] A document verification request is received from a user through an application, where the document verification request includes a converted document submitted by the user through the application.

[0088] Extract the first-time notarization result from the conversion document submitted by the user.

[0089] The interactive interface of the target blockchain is called to verify the primary evidence result in the conversion document submitted by the user, and when the primary evidence result in the conversion document submitted by the user passes the verification, the original electronic document corresponding to the primary evidence result in the conversion document submitted by the user is returned to the user.

[0090] On the basis of the above-mentioned embodiments, this embodiment also provides a method for verifying the authenticity of an electronic document after it is stored. That is, under the premise that the document security requirements are not high, the original electronic document corresponding to the primary storage result in the converted document submitted by the user can be directly returned to the user for self-verification.

[0091] In a possible specific implementation, a user can scan the readable information (QR code or character string) in the converted document (electronic document or printed copy) held by the user through the WeChat applet or other application. The WeChat applet or other application automatically submits the primary evidence result corresponding to the readable information to the background system (which may correspond to the execution subject in the embodiment of the present invention). After receiving the primary evidence result, the interactive interface of the target blockchain is called to verify the primary evidence result in the converted document submitted by the user (that is, check whether the specified document information is stored in a specific block / transaction). If the verification is successful, the corresponding original electronic document is obtained according to the primary evidence information and returned to the user.

[0092] In summary, the secondary evidence storage method and verification method provided by the embodiments of the present invention support users to distribute, view, and verify the stored result documents in a variety of ways, and a variety of verification means (corresponding to verifications under different permissions / scenarios, among which the first possible implementation method corresponds to verification by the operator, the second possible implementation method corresponds to verification by an independent third party, and the third possible implementation method corresponds to manual verification by the holder) can verify each other, thereby effectively solving the verification problem after traditional document distribution and having a wider range of applications.
