The embodiments of the present invention will be described below with reference to the drawings.
The embodiment of the invention provides a processing system of bill information, which is used for realizing chaining of bills based on an alliance chain system; referring to fig. 1, the system includes: a local server 10, an interplanetary file system 20, and a federation chain system including an uplink organization 30, and the uplink organization 30 includes a ticket uplink node 31.
The local server 10 is used to acquire the ticket information and upload the ticket information to the interplanetary file system 20. The interplanetary file system 20 is configured to perform hash processing on the ticket information to determine a primary hash value, perform hash processing on the primary hash value again to determine a secondary hash value, and then return the secondary hash value to the local server 10. The local server 10 obtains the secondary hash value returned by the interplanetary file system 20, and sends the secondary hash value and the ticket identifier corresponding to the ticket information one by one to the ticket uplink node 31. The note uplink node 31 is configured to generate uplink transaction information, where the transaction information includes a secondary hash value and a note identifier uplink.
In the embodiment of the present invention, the local server 10 is a server that has the right to directly obtain the ticket, and the local server is generally located in a secure network and is inaccessible to unauthorized devices. After acquiring the ticket information, the local server 10 may upload the ticket information to an InterPlanetary File System (IPFS) for storage, where the InterPlanetary File System 20 is a trusted distributed storage cluster and may include multiple IPFS servers; the interplanetary file system 20 and the local server 10 may belong to the same network.
After the interplanetary file system 20 acquires the ticket information, Hash processing can be performed on the ticket information, so as to generate a corresponding Hash value, namely a primary Hash value (primary Hash); meanwhile, the interplanetary file system 20 establishes an association relationship between the primary hash value and the ticket information (or the storage address of the ticket information), so that the interplanetary file system 20 can obtain corresponding ticket information based on the primary hash value. In addition, the interplanetary file system 20 in this embodiment further performs Hash processing on the primary Hash value again to calculate a Hash value of the primary Hash value, that is, a secondary Hash value (secondary Hash), and returns the secondary Hash value of the ticket information to the local server 10.
In this embodiment, a unique ticket Identifier (ID) may be set for each piece of ticket information, that is, the ticket information and the ticket identifier are in one-to-one correspondence. After receiving the secondary hash value, the local server 10 may send the secondary hash value of the ticket information and the ticket id to the ticket chaining node 31 of the blockchain system, so as to store the ticket id and the corresponding secondary hash value in the form of a blockchain. Based on the characteristics of the IPFS, the corresponding files can be directly obtained through the hash of the files, namely, the corresponding bill information can be determined based on the primary hash value, the secondary hash value is generated through secondary hash operation in the implementation, the primary hash value cannot be determined in reverse from the secondary hash value, so that the bill information cannot be directly obtained based on the secondary hash value disclosed in the block chain, and the bill information is prevented from being leaked while the chain link of the bill information is realized.
Specifically, the block chain system in this embodiment is a union chain system, which includes an Organization (Organization) for implementing information uplink, i.e., an uplink Organization 30; the local server 10 sends the secondary hash value and the ticket id to the ticket uplink node 31 in the uplink organization 30, and the ticket uplink node 31 can uplink the transaction information including the secondary hash value and the ticket id, so as to store the transaction information into the block chain. In which, the existing uplink method can be adopted for information uplink, and will not be described in detail here.
Alternatively, the financial document is generally stored in a picture format, and for convenience of transmission, the local server 10 encodes the document in a picture format to generate document information capable of network transmission in the embodiment. Specifically, the process of the local server 10 acquiring the ticket information includes: acquiring a bill picture; and coding the bill picture, and converting the bill picture into bill information capable of being transmitted through a network. The service personnel can generate a bill picture by scanning or shooting a bill with a mobile phone, and the bill picture is uploaded to the local server 10. The local server 10 may use the encoding mode ticket picture encoded by base64 to perform encoding processing; or, the bill picture is converted into a matrix form to realize coding, and each element in the matrix can represent the gray value or the RGB value of each pixel in the bill picture. In this embodiment, the local server 10 may be a web server to facilitate the subsequent uploading of the ticket information.
In the processing system of the ticket information provided by the embodiment of the present invention, the local server 10 uploads the sensitive ticket information to the credible interplanetary file system 20 for storage, uploads the secondary hash value of the ticket information returned by the interplanetary file system 20 as a credential to the alliance chain system, and only stores the secondary hash value in a block chain manner. Because the bill information can not be obtained based on the secondary hash value, the bill information can not be exposed in the nodes of the alliance chain system, the nodes in the alliance chain system can realize the tracing of the corresponding bill information through the secondary hash value, and can judge whether the bill information is tampered, so that the authenticity of the bill information can be ensured while the privacy of the bill information is ensured. Based on the interplanetary file system, a large number of files can be linked, the interplanetary file system has safety protection, and other equipment cannot obtain original bill information without authorization and also has higher safety.
On the basis of the above embodiment, referring to fig. 2, the federation chain system further includes a validation organization 40, and the validation organization 40 includes a ticket validation node 41. Specifically, the bill validation node 41 is configured to send a validation request containing an identification of the bill to be validated to the interplanetary file system 20 when the transaction information in the alliance chain system needs to be validated.
The interplanetary file system 20 is configured to return the one-time hash value to be verified corresponding to the ticket id to be verified to the ticket verification node 41. The bill verification node 41 is further configured to determine whether the secondary hash value to be verified is the same as the secondary hash value generated after the primary hash value to be verified is subjected to hash processing, and determine that the transaction information to be verified is legal when the two are the same; the ticket identification to be verified is the ticket identification in the transaction information to be verified, and the secondary hash value to be verified is the secondary hash value in the transaction information to be verified.
In the embodiment of the present invention, the alliance chain system at least includes two organizations, one is an organization that needs to upload a bill, i.e. the uplink organization 30; the other is the organization responsible for interrogating the validation ticket, validation organization 40. After the uplink organization 30 stores the transaction information into the block chain of the alliance chain system, if the transaction information needs to be verified, the bill verification node 41 of the verification organization 40 can find a corresponding bill identifier, namely a to-be-verified bill identifier, in a manner of inquiring the block chain account book, wherein the to-be-verified bill identifier is the bill identifier in the transaction information to be verified; the bill validation node 41 then sends the identification of the bill to be validated to the interplanetary file system 20, and validation is performed.
When the interplanetary file system 20 generates the hash value (including the primary hash value and the secondary hash value) of the ticket information, the association relationship between the ticket information and the corresponding ticket identifier is established. After receiving the authentication request sent by the ticket authentication node 41, the one-time hash value to be verified (also one-time hash value in essence) corresponding to the ticket identification to be verified (also one ticket identification in essence) can be returned to the ticket authentication node 41 based on the association relationship. Wherein, the bill identification in the interplanetary file system 20 can be uploaded together when the local server 10 uploads the bill information; or the interplanetary file system 20 generates a bill identifier after acquiring the bill information, and sends the bill identifier to the local server 10; alternatively, the interplanetary file system 20 generates the ticket id of the ticket information in the same manner as the local server 10.
After receiving the primary hash value to be verified, the bill verification node 41 performs hash processing on the primary hash value to be verified to generate a corresponding secondary hash value, and compares the secondary hash value with the secondary hash value in the transaction information to be verified (i.e., the secondary hash value to be verified stored in the block chain), and if the two hash values are the same, it indicates that the transaction information to be verified is legal and the bill information in the interplanetary file system 20 is not tampered; if the two are not the same, the bill information in the interplanetary file system 20 is tampered.
Optionally, the transaction information generated by the uplink node 31 of the ticket further includes a timestamp and ticket description information; the timestamp may be the time when the uplink node 31 of the ticket generates the transaction information, or the time when the local server 10 receives the secondary hash value; the ticket description information is information related to the ticket information, such as the type of the ticket, the owner of the ticket, the time of generation of the ticket, and the like, and is specific to the business scenario. Meanwhile, when the transaction information is verified, the bill verification node 41 also judges whether the timestamp and the bill description information in the transaction information to be verified are tampered, and when the timestamp and the bill description information are not tampered, the transaction information to be verified is determined to be legal. Since the blockchain is a chained memory structure, which is all time-stamped, the merkel root of the chained memory structure changes if the time stamp changes. Similarly, the ticket description information is the same. Therefore, the present embodiment can realize the verification of the time stamp and the ticket description information by verifying whether the mercker root is matched.
In the embodiment, by arranging the verification organization 40 for verification in the alliance chain system, the verification of the transaction information in the blockchain can be realized based on the bill verification node 41 in the verification organization 40; in addition, the interplanetary file system 20 only feeds back the hash value once in the verification process, so that the bill information cannot be revealed in the verification process, and the privacy and the safety of the information can be ensured.
On the basis of the above embodiment, referring to fig. 3, the federation chain system further includes a sequencing node; meanwhile, the uplink organization 30 further includes an endorsement node and a billing node.
Specifically, after the receipt uplink node 31 generates the transaction information, it forms a proposal containing the transaction information and sends the proposal to the endorsement node. The endorsement node is configured to endorse a signature to the proposal based on a preset endorsement policy, and return a corresponding signature to the note uplink node 31.
The note uplink node 31 is used to send the proposal and the corresponding signature to the sequencing node. The sequencing node is used for sequencing the transaction information, packaging the sequenced transaction information into a block and distributing the block to the accounting node. And the accounting node verifies the signature according to a preset endorsement strategy and records a block containing the transaction information.
Optionally, the uplink organization 30 further comprises an authentication node. Wherein, the note uplink node 31 sends an authentication request to the authentication node; the authentication node authenticates the note uplink node 31 based on the authentication request, and issues a certificate to the note uplink node 31 when the authentication is passed; after acquiring the certificate, the note uplink node 31 sends the corresponding proposal to the endorsement node. In the embodiment of the present invention, the uplink organization 30 further includes an endorsement node (Endorser peer), an accounting node (commit peer), and an authentication node (CA), and the sequencing of the transaction information is implemented by a sequencing node (order peer). The workflow of the system is described in detail below in conjunction with fig. 3.
When the stored bill needs to be uploaded, the staff collects the bill picture of the bill through the user client (such as a smart phone or a tablet computer), and uploads the bill picture to the local server 10.
The local server 10 encodes the ticket picture into ticket information and uploads the ticket information to the IPFS, i.e. the interplanetary file system 20.
The IPFS calculates a Hash value of the ticket information based on an algorithm such as MD5 or SHA1, determines a primary Hash, and calculates the Hash again to determine a secondary Hash, and then returns the secondary Hash to the local server 10.
The local server 10 sends the secondary Hash and the corresponding ticket Identification (ID) to the ticket chaining node 31. In fig. 3, the local server 10 sends the ID of the ticket information and the secondary Hash returned by the IPFS to the nodjs server belonging to the ticket uplink node 31 of the federation chain system by means of the Http request.
The ticket uplink node 31 sends an authentication request to an authentication node in the uplink organization 30 in advance to apply for a certificate, and when the authentication is passed, the authentication node returns the certificate to the ticket uplink node 31. When the note uplink node 31 receives the ID and the secondary Hash, it generates transaction information, executes a chain code (smart contract) to form a proposal, and sends the proposal to an endorsement node of the uplink organization 30 to request endorsement. After signing by the endorsement node, the corresponding signature is returned to the note uplink node 31. The note uplink node 31 then sends the proposal and corresponding signature to the sequencing node.
The sequencing node sequences the transaction information, packs the transaction information into blocks according to a certain rule, and then distributes the transaction information to the corresponding accounting node, so that the accounting node can record the blocks containing the transaction information, and uplink of the transaction information is realized. Wherein, different organizations in the alliance chain system can be provided with a billing node, and the endorsement node and the like can also be used as a billing node.
When transaction information in the blockchain needs to be verified, the bill verification node 41 executes a corresponding verification chain code, and the logic of the chain code is as follows: and inquiring the block chain account book, finding out the bill ID, acquiring corresponding primary Hash (namely the primary Hash value to be checked) from the IPFS according to the ID, calculating secondary Hash, and comparing whether the secondary Hash is consistent with the secondary Hash (namely the secondary Hash value to be checked) recorded on the chain. Meanwhile, whether the time stamp, the bill description information and the like are tampered or not can be verified.
The ticket validation node 41, after determining the validation result, may send the validation result as a transaction message to the sequencing node for sequencing. In addition, the ticket validation node 41, like the ticket chaining node 31, requires authenticated node authentication and endorsement node signature endorsement.
In the processing system of the ticket information provided by the embodiment of the present invention, the local server 10 uploads the sensitive ticket information to the credible interplanetary file system 20 for storage, uploads the secondary hash value of the ticket information returned by the interplanetary file system 20 as a credential to the alliance chain system, and only stores the secondary hash value in a block chain manner. Because the bill information can not be obtained based on the secondary hash value, the bill information can not be exposed in the nodes of the alliance chain system, the nodes in the alliance chain system can realize the tracing of the corresponding bill information through the secondary hash value, and can judge whether the bill information is tampered, so that the authenticity of the bill information can be ensured while the privacy of the bill information is ensured. Based on the interplanetary file system, a large number of files can be linked, the interplanetary file system has safety protection, and other equipment cannot obtain original bill information without authorization and also has higher safety. By arranging the verification organization 40 for verification in the alliance chain system, the verification node 41 can realize the verification of the transaction information in the blockchain based on the bill in the verification organization 40; in addition, the interplanetary file system 20 only feeds back the hash value once in the verification process, so that the bill information cannot be revealed in the verification process, and the privacy and the safety of the information can be ensured.
An embodiment of the present invention further provides a method for processing ticket information, where the method is executed by a local server capable of acquiring the ticket information, and as shown in fig. 4, the method includes:
step 401: acquiring the bill information, uploading the bill information to the interplanetary file system, instructing the interplanetary file system to perform hash processing on the bill information to determine a primary hash value, and performing hash processing on the primary hash value again to determine a secondary hash value.
Step 402: and acquiring a secondary hash value returned by the interplanetary file system, sending the secondary hash value and the note identification corresponding to the note information one by one to a note uplink node of the alliance chain system, and indicating the note uplink node to generate uplink transaction information, wherein the transaction information comprises the secondary hash value and the note identification uplink.
Optionally, the step 401 of "acquiring the ticket information" may include:
step A1: and acquiring a bill picture.
Step A2: and coding the bill picture, and converting the bill picture into bill information capable of being transmitted through a network.
Optionally, the method further comprises:

In the embodiment of the present invention, the processing method of the ticket information is executed by the local server, and the detailed process thereof can refer to the description in the above embodiment, which is not described herein again. In the processing method of the bill information, the local server 10 uploads the sensitive bill information to the credible interplanetary file system 20 for storage, uploads the secondary hash value of the bill information returned by the interplanetary file system 20 as a certificate to the alliance chain system, and only stores the secondary hash value in a block chain manner. Because the bill information can not be obtained based on the secondary hash value, the bill information can not be exposed in the nodes of the alliance chain system, the nodes in the alliance chain system can realize the tracing of the corresponding bill information through the secondary hash value, and can judge whether the bill information is tampered, so that the authenticity of the bill information can be ensured while the privacy of the bill information is ensured. Based on the interplanetary file system, a large number of files can be linked, the interplanetary file system has safety protection, and other equipment cannot obtain original bill information without authorization and also has higher safety. By arranging the verification organization 40 for verification in the alliance chain system, the verification node 41 can realize the verification of the transaction information in the blockchain based on the bill in the verification organization 40; in addition, the interplanetary file system 20 only feeds back the hash value once in the verification process, so that the bill information cannot be revealed in the verification process, and the privacy and the safety of the information can be ensured.

and coding the bill picture, and converting the bill picture into bill information capable of being transmitted through a network.
On the basis of the above embodiment, the apparatus further includes a verification module:
the verification module is used for indicating the interplanetary file system to return a to-be-verified primary hash value corresponding to a to-be-verified note identifier to the note verification node when the interplanetary file system receives a verification request which is sent by the note verification node of the alliance chain system and contains the to-be-verified note identifier if the transaction information in the alliance chain system needs to be verified, and determining that the transaction information to be verified is legal when the to-be-verified secondary hash value is the same as a secondary hash value generated after the to-be-verified primary hash value is subjected to hash processing; the ticket identification to be verified is the ticket identification in the transaction information to be verified, and the secondary hash value to be verified is the secondary hash value in the transaction information to be verified.
In the processing device of the bill information, the local server uploads the sensitive bill information to a credible interplanetary file system for storage, uploads a secondary hash value of the bill information returned by the interplanetary file system as a certificate to a alliance chain system, and only stores the secondary hash value in a block chain mode. Because the bill information can not be obtained based on the secondary hash value, the bill information can not be exposed in the nodes of the alliance chain system, the nodes in the alliance chain system can realize the tracing of the corresponding bill information through the secondary hash value, and can judge whether the bill information is tampered, so that the authenticity of the bill information can be ensured while the privacy of the bill information is ensured. Based on the interplanetary file system, a large number of files can be linked, the interplanetary file system has safety protection, and other equipment cannot obtain original bill information without authorization and also has higher safety. By arranging a verification organization for verification in the alliance chain system, verification of transaction information in the blockchain can be realized based on a bill verification node in the verification organization; and the interplanetary file system only feeds back the hash value once in the verification process, so that the bill information cannot be revealed in the verification process, and the privacy and the safety of the information can be ensured.
