It should also be understood that in some embodiments, the devices described above are not portable communication devices, but rather are desktop computers having touch-sensitive surfaces (e.g., touch screen displays and/or touch pads).
Specifically, the user may store the ticket information uploading blockchain, and may be any ticket information that needs to be processed by the processing node, for example, the ticket information may be a certificate for insurance reimbursement, or a document to be checked and signed, which is not limited in this embodiment of the present application.
The user node can select to forward the first bill information to be processed to the processing node for processing. A plurality of processing nodes can be added and managed in the block chain, and names and addresses of the plurality of processing nodes are stored in the block chain, and first, a user can select the target node address through terminal operation, that is, the processing node address for processing the first bill, for example, if the user inputs a name, a abbreviation or a number of a processing mechanism, the processing node can be queried through the block chain. In an optional implementation mode, selectable processing nodes can be recommended to the user node, and the user node can inquire and select. The target node address may be one or more, and in the case where the user selects a plurality of processing nodes, the processing may be performed in sequence, allowing one processing node to acquire data at a time.
In an optional implementation manner, before determining, according to a user operation, an address of a target node at which the first ticket information is processed, the method further includes:
acquiring the latest state information of a plurality of processing nodes from a block chain, and determining a processing node to be selected, of which the latest state information is in a normal working state, from the plurality of processing nodes;
determining at least one processing node as a recommended processing node in the processing nodes to be selected according to the processing content of the bill information, and displaying the recommended processing node;
the user operation includes a selection operation of at least one of the recommended processing nodes.
Each processing node may issue latest status information in the blockchain to notify other nodes of knowing a current status, such as whether the processing node is idle or busy, or in a status of stopping processing data, and the like, and the user node may obtain the latest status information of the plurality of processing nodes from the blockchain, and determine, from the plurality of processing nodes, the processing node to be selected whose latest status information is in a normal operating status, where the normal operating status may be understood as a status of not stopping processing data. The user can be prevented from selecting a processing node that cannot process data in time.
Specifically, each processing node may have one or more authentication tags and store the one or more authentication tags in the blockchain, and by matching the processing content of the ticket information with the authentication tags, at least one processing node may be determined as a recommended processing node among the processing nodes to be selected, where the authentication tag of the recommended processing node is relatively more matched with the processing content of the ticket information. And displaying the recommended processing nodes to a user at a user node, wherein the user can select at least one recommended processing node from the recommended processing nodes and use the recommended processing node as a processing node of the bill information to obtain the address of the node, namely the target node address.
The intelligent recommendation of the processing node may also be implemented in various ways, which is not limited in the embodiment of the present application.
After determining the destination node address for processing the first ticket information, step 202 may be performed.
202. And acquiring the public key of the user node and the public key of the target node address, and signing the first bill information based on the public key of the user node and the public key of the target node address to generate multiple signature data of the first bill information.
In one embodiment, some ticket information may be encrypted and decrypted in block chains based on a form of Public Key and private Key (PrivateKey). The public key and the private key are a key pair (i.e. a public key and a private key) obtained through an algorithm, the public key is a public part of the key pair, and the private key is a non-public part. The public key is typically used to encrypt session keys, verify digital signatures, or encrypt data that can be decrypted with a corresponding private key. The key pair derived by such an algorithm is guaranteed to be unique worldwide. When using this key pair, if one of the keys is used to encrypt a piece of data, the other key must be used to decrypt the piece of data. For example, encrypting data with a public key necessitates decryption with the private key, and if encrypting with the private key, also must decrypt with the public key, otherwise decryption will not succeed.
After the user node determines the address of the target node for processing the first bill information, the public key of the user node and the public key of the address of the target node may be obtained, and the node public key in the blockchain may be queried and obtained for use.
In a distributed network of a block chain, communication among nodes and trust achievement can depend on a digital signature technology, and digital signatures relate to tools such as public keys, private keys, wallets and the like, and have two functions: firstly, the message is proved to be actually signed and sent out by the message sender; the second is to determine the integrity of the message.
Public key encryption (also referred to as asymmetric encryption) involved in blockchains is a cryptographic system that uses a pair of keys (public and private) for encryption. Public keys can be widely distributed, but private keys are only known to their owners. The keys are always created in pairs, and each public key must have a corresponding private key. Public key encryption is often used to encrypt messages between two persons or two computers in a secure manner. Anyone can encrypt information using one's public key, but once encrypted, the message can only be decrypted using the corresponding private key.
The multiple signatures are understood to mean that, when a destination node address is selected, encryption is performed using two public keys of the user node and the destination node. So that the ticket information can be decrypted and obtained by the private keys of the two (or any one).
In an optional implementation manner, the number of the destination node addresses that process the first ticket information is at least two, and the method further includes:
determining a processing sequence of the at least two target node addresses according to user operation;
the transferring the multiple signature data of the first ticket information to the destination node address through the blockchain includes:
and determining a first processing node of the at least two destination node addresses according to the processing order, transmitting multiple signature data of the first ticket information and the processing order to the first processing node so that the first processing node processes the first ticket information to obtain second ticket information, determining a second processing node of the at least two destination node addresses, generating multiple signature data of the second ticket information based on a public key of the first processing node and a public key of the second processing node, and forwarding the multiple signature data to the second processing node.
Further optionally, after the sending the multiple signature data of the first ticket information and the processing order to the first processing node, the method further includes:
and receiving target bill information from a terminal node, wherein the terminal node is the last processing node in the processing sequence.
The processing sequence of the bill information can be preset according to the requirement at the user node, so that the processing flow can be carried out more regularly and orderly. For one processing node, the public keys of the node and the next node are used for carrying out multiple signatures on the bill information, and the bill information is forwarded to the next node for analysis and processing, and so on. And sending back the processed bill information to the user node until the last processing node (terminal node) specified in the processing sequence, wherein the terminal node can sign the target bill information by using the private key of the terminal node.
The digital signature technique is to encrypt the digest information with the sender's private key and transmit it to the receiver together with the original text. The receiver can decrypt the encrypted digest information only with the sender's public key, and then generates a digest information for the received original text using a HASH (HASH) function, which is compared with the decrypted digest information. If the information is the same as the received information, the received information is complete and is not modified in the transmission process, otherwise, the information is modified. The digital signature is able to verify the integrity of the information.
The user node can use the terminal node public key to verify the source of the target bill information, and after the verification is successful, the processing can be linked up to complete the processing flow of the bill information.
If the user node sets a plurality of target node addresses, which indicates that a plurality of processing nodes are to execute processing, but the processing sequence is not set, one processing node can be randomly selected for processing. It should be appreciated that since the blockchain is a decentralized, distributed database, each time data is processed, one of the servers in the blockchain network needs to be selected as an executor to process the data. The rule for selecting the server each time is a Consensus mechanism, which in the embodiment of the present application may be a workload certification mechanism (Proof of Work, POW), an equity certification mechanism (Proof of stamp, POS), a Ripple Consensus mechanism (Ripple Consensus), an authorized equity certification mechanism (DPOS), and the like, and is not limited herein.
The method executed by each processing node according to the processing sequence may specifically refer to the description in the embodiment shown in fig. 3, and is not described herein again.
203. And transferring the multiple signature data of the first bill information to the target node address through a block chain.
After the aforementioned signature processing is performed on the first ticket information, the obtained multiple signature data of the first ticket information may be sent to the destination node address, so that the processing node of the destination node address may perform decryption using the node private key. The first bill information is obtained, and the safety of the bill information is guaranteed.
The processing node that obtains the first ticket information may process the first ticket information according to its own node processing rule, and specifically, may add other information on the basis of the first ticket information to obtain the second ticket information. In the application scenario of insurance reimbursement, the additional information may be determined reimbursement contents, such as reimbursement items, reimbursement amounts and/or reimbursement proportions.
For example, when the bill is a medical consumption list of one of the insurance reimbursement vouchers, the consumption content may need different insurance claim settlement institutions or insurance companies to review the part meeting the self-specified reimbursement and feed back to the user. Therefore, the user can forward the medical consumption list to the institutions in turn, check the medical consumption list at any structural node, and determine the reimburseable part, for example, institution a determines that drug a and drug c can be reimbursed, the reimbursement amount is m, or the reimbursement proportion is n%.
After the processing node of the target node address finishes processing the first bill information, the obtained second bill information can be encrypted by using the public key of the node and the public key of the user node and then is sent back to the user node, so that the user node can decrypt by using the private key of the user node to obtain the second bill information, and the processing of the first bill information is finished. The above steps may be to complete the processing flow of one processing node, and the user may send the obtained second ticket information to other processing nodes for processing in the same manner until all required processing is completed.
204. And initiating an acquisition request under the condition that the processed bill information sent by the target node address is not received, wherein the acquisition request is used for requesting to analyze the multiple signature data of the first bill information by using the private key of the user node.
In order to avoid the situation that the processing node cannot process the bill information in time due to various factors and delays the processing flow, the user can also initiate an acquisition request to extract the first bill information. The multiple signature data of the first bill information is encrypted by the destination node address and the public key of the user node, so that the multiple signature data can be decrypted by using the private key of the user node to obtain the first bill information from the processing node.
In an optional implementation manner, after initiating the obtaining request, the method further includes:
judging whether the time length of the multiple signature data of the bill information after being transferred to the target node address is larger than a preset time length threshold value or not;
if yes, triggering the step of obtaining the bill information from the target node address.
Specifically, after the user sends the first bill information to the processing node for processing, the first bill information can be retrieved only after a certain preset time length is reached, that is, the preset time length threshold value can be set in the block chain, when the user node initiates an acquisition request, whether the time length after the multiple signature data of the bill information is transferred to the target node address is greater than the preset time length threshold value or not can be judged, if so, the bill information can be obtained from the target node address through private key analysis, and if not, the bill information cannot be obtained from the target node address through private key analysis, so that the user operation is normalized, and the high-frequency data transfer processing on the block chain is reduced.
205. And obtaining the first bill information from the target node address.
