Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Establishing relations between transferors and transferees on third-party institutions, such as financial institutions with credit transfer management and credit platform, and applying corresponding transferors and transferee processing terminals respectively; and in order to ensure the security of three-party data communication, a group of public and private key pairs needs to be generated by a processing end in advance by the third organization: the public/private key data of the transferor and the transferee are also called local public/private key data, and the public/private key data of the third party mechanism are also called local public/private key data; in order to ensure that the creditor information is not tampered, the third-party organization uses a certificate-depositing block chain to deposit and disclose the creditor information which is successfully transferred; the credit block chain provides services for each creditor information transfer party by developing an upper-layer application interface, for example, a credit creating, acquiring and cancelling interface is provided for a third-party organization, and only a credit acquiring interface is provided for a transferor, an transferee and even a creditor; when a transferor initiates an assignment operation, a transferor processing end is used to send first ciphertext data carrying a creditor information deposit certificate identifier to be transferred to a third party institution processing end, an embodiment of the present invention provides a processing method of creditor information, after the first ciphertext data is obtained, a corresponding processing flow of the creditor information is activated to complete an assignment operation of a creditor, as shown in fig. 1, which is a schematic diagram of a processing method of creditor information provided by an embodiment of the present invention, the method mainly includes the following steps:
and step 1, receiving first ciphertext data sent from a transferor processing terminal.
Specifically, the third-party organization processing end receives the first ciphertext data from the transferor processing end; here, the data Transfer Protocol between the third party organization process side and the transferor process side may be a Hypertext Transfer Protocol (HTTP) or a Hypertext Transfer Protocol security Protocol (HTTPs). In the embodiment of the invention, data communication related to the creditor transaction link is transmitted in a ciphertext mode so as to ensure that the transaction privacy is not leaked.
the method specifically comprises the following steps: step 21, decrypting the first ciphertext data to obtain first plaintext data; wherein the first plaintext data comprises first identification data and first signature data;
specifically, the third-party mechanism processing end uses preset local private key data to decrypt the first ciphertext data to generate first plaintext data;
here, the third party organization processing end carries out decryption processing according to a set asymmetric algorithm, wherein the asymmetric algorithm is an RSA algorithm of a public key cryptosystem, an elliptic curve algorithm and a SM2 algorithm; the first identification data is a credit card deposit identification of credit right information corresponding to the credit right to be transferred, which is known by three parties, on a credit card deposit block chain; the first signature data is electronic signature data which ensures that the first identification data is not tampered in data transmission and is made for the first identification data;
here, a method of calculating signature data and encrypted data in three-party transmission data will be described:
1) signature data fEncryption(information summary data, sender private key data), wherein, the information summary data is fAbstract(original text) which is the specific data currently transmitted, wherein the original text in the step is the first identification data, fAbstractCalculating a function for the digital summary information; f. ofAbstractThe digital Digest information Algorithm used can be a Message-Digest Algorithm (MD) -5 Algorithm, a Secure Hash Algorithm (SHA) -256 Algorithm, or a secret cryptographic Hash Algorithm SM3 Algorithm; f. ofEncryptionIs an asymmetric encryption function;
2) encrypted data fEncryption(plaintext, receiver public key data), plaintext + signature data;
therefore, after receiving the first ciphertext data sent by the transferor processing end, decrypting the first ciphertext data by using the receiver public key data encrypted and used by the transferor processing end, namely the third party organization private key data corresponding to the third party organization public key data, namely the local private key data, so as to obtain plaintext data with an original text and a signature, wherein the original text is the first identification data, and the signature is the first signature data;
step 22, according to the first identification data, performing first data signature verification on the first signature data;
specifically, the public key data of the transferor is used for decrypting the first signature data to generate first temporary plaintext data; performing digital abstract calculation processing on the first identification data to generate first abstract data; when the first temporary plaintext data is the same as the first abstract data, the first data is successfully verified;
here, referring to the description of the signature calculation in step 21, when checking the signature, first, the sender private key data encrypted with the signature, that is, the sender public key data corresponding to the transferor private key data, that is, the transferor public key data, is used to decrypt the first signature data, and then the digital digest data to be verified, that is, the first plaintext data, can be obtained; then, carrying out digital abstract calculation with the same algorithm as that of the transferor on the original text, namely the first identification data to obtain first abstract data for verification; if the first temporary plaintext data is the same as the first abstract data, the first temporary plaintext data indicates that the first identification data is not tampered in transmission;
and step 23, if the first data is successfully checked, using the first identification data as first certificate storage identification data.
Here, only if the verification in step 22 is passed, it can be stated that the transmitted data is not tampered, and the first identification data can be used as the first verification identification data for the subsequent steps.
the first creditor information comprises first content rule information, first transferrable information, first creditee signature information and first endorser signature information.
The evidence-storing block chain converts the identification data and the block address of the input first evidence-storing identification data to obtain a corresponding block address, positions the block address on a block corresponding to the block address according to a block chain address routing strategy, extracts stored creditor information from a resource pool corresponding to the block, and finally returns the creditor information to a processing end of a third-party mechanism; the first creditor information is the current creditor agreement to be transferred with the creditor, wherein the agreement content at least is the first content rule information, the creditor transfer type is the first transferable information, the agreement payer electronic signature is the first creditee signature information, and the agreement payee electronic signature is the first endorser signature information.
Step 4, carrying out transfer evaluation on the first creditor information; if the assignment evaluation is passed, packaging the first certificate storage identification data to generate second ciphertext data;
the method specifically comprises the following steps: step 41, when the first transferable information is the transferable type, the transfer evaluation is passed;
here, the credit right is divided into multiple-transfer credit right and non-transfer credit right, and the corresponding first transferable information may also be a transferable type or a non-transferable type; whether the debt can be transferred is closely related to the obligation and obligation relation of the agreement constraint, and for the non-transferable type of the debt, if the transferee cannot find the debt in time, the condition that the debt cannot be accepted occurs, so that the transferee suffers from economic loss; therefore, in the claim information in the embodiment of the invention, not only the agreement content but also the claim transfer type are deposited, so that the full-information and all-around transparent display of the claim of the transferee on the claim per se is realized; in addition, the third-party mechanism of the embodiment of the invention also makes full use of the information to control the transferee's risk, and if the first transferable information is of an un-transferable type, the third-party mechanism immediately terminates the transfer operation of the debt right and timely sends out an early warning prompt to the transferee;
step 42, if the assignment evaluation is passed, performing first signature processing on the first certificate storage identification data to generate second signature data;
specifically, digital abstract calculation processing is carried out on the first certificate storage identification data to generate second abstract data; encrypting the second abstract data by using the local private key data to generate second signature data;
after confirming that the debt is a transferable debt, the whole content of the debt needs to be displayed to the transferee, that is, the first deposit certificate identification data is sent to the processing end of the transferee, and after the transferee finishes obtaining and content confirmation of the debt information corresponding to the first deposit certificate identification data through a deposit certificate block chain, the transferee confirms to receive the transfer of the debt by returning the electronic signature information of the transferee; as described above, in order to ensure the privacy of the transaction, the first certificate storing identification data is sent to the transferee terminal, and it is necessary to sign the first certificate storing identification data in advance to obtain the second signature data, and the processing mode of the signature is consistent with the processing mode described in step 21, which is not further described herein;
step 43, encrypting the first certificate storing identification data and the second signature data to generate second ciphertext data;
specifically, the preset public key data of the assignee is used for encrypting the first certificate storage identification data and the second signature data to generate second ciphertext data;
here, the processing manner of the encryption is consistent with the processing manner described in step 21, and further description is not provided herein.
Step 5, sending second ciphertext data to the processing end of the assignee; and receiving third ciphertext data transmitted from the assignee processing terminal.
After receiving the second ciphertext data, the assignee decrypts and verifies the second ciphertext data to obtain first certificate storage identification data; and then according to the identification data, acquiring corresponding first creditor information from the certificate storage block chain for information browsing, after confirming that no errors exist, signing and encrypting the electronic signature information of the electronic signature, and sending an encryption result, namely third encrypted data, to a third party institution processing end to show that the receiving and transferring are confirmed.
Step 6, analyzing the third ciphertext data to generate first assignee signature information; replacing the signature information of the first endorser in the first creditor information by using the signature information of the first transferee to generate second creditor information;
the method specifically comprises the following steps: step 61, decrypting the third ciphertext data by using the local private key data to generate second plaintext data, wherein the second plaintext data comprises first signature information and third signature data; performing second data signature verification on the third signature data according to the first signature information by using the public key data of the assignee; if the second data is successfully signed, the first signature information is used as the signature information of the first assignee;
here, the decryption processing method is similar to the foregoing step 21, and further description is omitted here; the processing manner of data signature verification is similar to that in the foregoing step 22, and further description is omitted here; if the second data signature verification is successful, the electronic signature information of the assignee is not tampered in the data transmission process, and the first signature information can be used as the signature information of the first assignee for subsequent steps;
step 62, the first endorser signature information in the first creditor information is replaced by the first transferee signature information, and the first content rule information, the first transferrable information, the first creditor signature information and the first transferee signature information form second creditor information.
Here, as described in step 3 above for the creditor information, the first creditor information includes first content rule information, first transferrable information, first creditee signature information, and first endorser signature information, the first endorser signature information should be the electronic signature information of the transferor, and after the transferee has confirmed the transfer of the creditor, new creditor information is generated, that is, the endorser electronic signature information is updated to the electronic signature information of the current transferee, that is, the first transferee signature information.
Step 7, storing second creditor information on the certificate storing block chain to generate second certificate storing identification data;
the method specifically comprises the following steps: using the certificate deposit block chain to perform certificate deposit establishment processing on the second creditor right information to obtain corresponding second certificate deposit identification data; and using the certificate storage block chain to carry out certificate storage revocation marking processing on the certificate storage data corresponding to the first certificate storage identification data.
Here, the second creditor information is a new creditor agreement to be transferred with the creditor, wherein the agreement content is not changed, so the agreement is still the first content detail information, the creditor transfer type is not changed, so the agreement payer is still the first transferable information, so the agreement payee is still the first creditee signature information, and the agreement payee is changed: the original first endorser, namely the transferor in the transfer process, is changed into the current second endorser, namely the transferee in the transfer process, so that the endorser signature information needs to be changed from the first endorser signature information into the second endorser signature information, namely the first transferee signature information;
after completing the new creditor agreement, the third party organization needs to do two things to complete the agreement validation operation: firstly, a new protocol is created, a certificate storage block chain is uploaded to the new protocol for certificate storage and public notice, after new creditor information is acquired, the certificate storage block chain performs digital summary calculation on the new protocol to generate corresponding summary data, a new resource pool is created for the certificate storage block chain to be used for storage, a new block is created for storing address information and summary data of the resource pool, the block is broadcasted to the whole chain, and finally identification data corresponding to the block, namely second certificate storage identification data, is sent back to a third-party institution processing end; and the second part is to invalidate the original relation between the debt and the debt right, after the certificate storage block chain acquires the first certificate storage identification data needing to be invalidated, the block corresponding to the certificate storage identification data is not deleted, but the attribute of the data resource is changed into invalid data on the block, and when the application party reads the invalid data again, the prompt that the protocol is invalidated can be seen.
Step 8, carrying out credit right change notification on the transferor, the transferee and the debtor respectively according to the second deposit certificate identification data;
the method specifically comprises the following steps: using the second deposit certificate identification data to carry out change notification splicing processing and generate credit right change notification data; and sending credit right change notification data to the transferor processing end, the transferee processing end and the debtor processing end respectively at preset first time intervals until receiving confirmation receiving data sent back from the transferor processing end, the transferee processing end and the debtor processing end.
Here, after the protocol effective operation of the above steps is completed, the transferor, the transferee, and the debtor must be notified; the notified content is that a third party mechanism sends a new credit right agreement credit card storage identification to a transferor, an acceptor and a debtor processing end through a third party mechanism processing end, namely second credit card storage identification data, and the second credit card storage identification data needs to be packaged in a specific format once when being transmitted, and the packaged result is credit right change notification data; the notification mode is different from the traditional one-time non-reply confirmation notification mode, and is a mode of continuing the notification without confirming and terminating: after sending the credit change notification data to the confirmer, namely the acquirer processing terminal, the acquirer processing terminal and the debtor processing terminal, if the confirmer processing terminal, the acquirer processing terminal and the debtor processing terminal all reply the confirmation receiving data, no data is continuously sent; if any party fails to reply the confirmation receiving data, the same creditor change notification data is continuously sent to the party processing terminal at an appointed time interval, namely at a first time interval, for example, at a week interval, until the party processing terminal replies the confirmation. Therefore, the problem that the transferor, the transferee and the debtor can not be notified in time, especially the debtor, is solved.
