The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention.

It should be further noted that, for the convenience of description, only some but not all of the relevant aspects of the present invention are shown in the drawings. Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.

Example one

Fig. 1 is a flowchart of a data processing method based on a blockchain according to an embodiment of the present invention, where the present embodiment is applicable to a case of uplink data after confirming security of data to be uplink, and the method can be performed by a data verification apparatus provided in an embodiment of the present invention, and the apparatus can be implemented by software and/or hardware, and can be generally integrated in a computer device, for example, a blockchain node. Accordingly, as shown in fig. 1, the method comprises the following operations:

s110, at least two pieces of data to be uplink are obtained.

Wherein, each data to be uplink comes from the data transmission device in different block chain nodes.

Specifically, the data verification device may be a device deployed in each blockchain node of the blockchain network, and the data verification devices in each blockchain node are independent from each other and may be used to verify whether uplink data to be acquired by the blockchain node is tampered or forged in the transmission process. The data transmission device may be a device independently deployed in any at least two blockchain nodes of the blockchain network, and the data transmission devices deployed in different blockchain nodes are independent of each other and may be used to transmit the data to be uplink to the data verification device. The data to be uplinked may be data to be verified that needs to be written to each blockchain node of the blockchain network.

Correspondingly, each block chain node of the block chain network is provided with a data verification device, part or all of the block chain nodes can be provided with a data transmission device, and the same block chain network needs at least two block chain nodes provided with data transmission devices. Each data transmission device can transmit the data to be uplink to the data verification device of each block chain node, and any data verification device can receive at least two data to be uplink transmitted by at least two data transmission devices.

In an optional embodiment of the present invention, the acquiring at least two copies of to-be-uplink data may include: receiving target transmission data sent by each data transmission device, and acquiring identification data of each data transmission device; under the condition that the identity identification data are determined to be legal, acquiring transmission signature data and transmission verification data of the target transmission data; and decrypting each piece of to-be-uplink data in each piece of target transmission data under the condition that each piece of target transmission data is determined to be reliable according to each piece of transmission signature data and each piece of transmission verification data is determined to be legal.

The target transmission data may be data transmitted from the data transmission device to the data verification device. The identification data may be data that uniquely identifies the data transfer device. The validity of the identification data can indicate that the data transmission device uniquely identified by the identification data can be used as a safe source of the data to be uplink. The transmission signature data may be a digital signature that the data transmission apparatus adds to the target transmission data before transmitting the target transmission data. The transmission verification data may be verification data that the data transmission apparatus adds to the target transmission data before transmitting the target transmission data according to negotiation with the data verification apparatus. The reliability of the target transmission data may mean that it can be determined from the transmission signature data that the target transmission data has not been tampered with. The transmission of the authentication data may be legal, which means that the transmission of the authentication data is agreed with the negotiation of the data transmission apparatus and the data authentication apparatus.

Specifically, when the data transmission device needs to transmit the data to be uplink-linked to the data verification device, the data transmission device can generate target transmission data according to the data to be uplink-linked, so that the data to be uplink-linked can be transmitted to the data verification device by sending the target transmission data to the data verification device. In order to ensure security of data during transmission between the data transmission device and the data verification device, the data transmission device may add transmission verification data to the target transmission data before sending the target transmission data. The transmission verification data may be determined by negotiation between the data transmission device and the data verification device, may be determined by negotiation between the data transmission device and the data verification device in real time before the data transmission device sends the target transmission data, or may be periodically negotiated between the data transmission device and the data verification device to periodically update the transmission verification data, which is not limited herein. The data transmission apparatus may further add transmission signature data to the target transmission data to which the transmission verification data is added, to encrypt it, before transmitting the target transmission data. The specific method for adding the transmission signature data to the target transmission data may include any available digital signature technology, and is not limited herein.

Accordingly, the data verification device may receive the target transmission data sent by the data transmission device, and the data verification device needs to establish a communication relationship with the data transmission device, so as to obtain the identification data of the data transmission device. The identity of the data transmission device can be determined through the identity identification data, so that whether the data transmission device is a data transmission device normally deployed in a blockchain node of a blockchain network can be judged. Alternatively, the identification data may include an IP (Internet Protocol Address) Address and/or a MAC (Media Access Control) Address of the data transmission device.

Further, under the condition that the identification data of the data transmission device is determined to be legal, the data transmission device sending the target transmission data can be determined to have safety, and then the data verification device can further acquire the transmission signature data and the transmission verification data of the target transmission data. Based on the digital signature technology, the data verification device can verify whether the target transmission data is sent by the data transmission device according to the transmission signature data and is not tampered in the transmission process, and if so, the target transmission data can be determined to be reliable. Based on the transmission verification data negotiated with the data transmission device in advance, the data verification device may verify whether the transmission verification data of the target transmission data is consistent with the negotiation determination, and if so, may determine that the transmission verification data is legitimate. Therefore, under the condition that the target transmission data is determined to be reliable according to the transmission signature data and the transmission verification data is determined to be legal, the target transmission data can be determined not to be tampered in the process of being sent to the data verification device by the data transmission device, and the to-be-uplink data can be further decrypted in the target transmission data. The specific method for decrypting the to-be-uplink data in the target transmission data may correspond to an encryption processing method adopted when the to-be-uplink data generates the target transmission data, and is not limited herein.

In an optional embodiment of the present invention, after acquiring at least two copies of to-be-uplink data, the method may further include: and writing the data to be uplinked into a verification partition of the blockchain node.

The verification partition may be a storage area in the block link point for storing to-be-verified uplink data.

Correspondingly, the verification partition may be a storage area previously deployed in the blockchain node, and may be accessed by the data verification apparatus for reading and writing data. After the data to be uplink is acquired, in order to avoid the risk of tampering after the data to be uplink is acquired, the data verification device can write the data to be uplink into the verification partition of the block link point through the data contract, so that the written data to be uplink can be read and further verified after the data to be uplink is written into the verification partition.

And S120, under the condition that all the data to be uplink linked are determined to have consistency, performing data logic verification on any data to be uplink linked to obtain a logic verification result of the data to be uplink linked.

Where consistency may be an attribute that describes data consistency. Data logic verification may be an operation to verify whether data satisfies logic that it has not been tampered with or forged. The logical verification result may be a result describing whether the to-be-uplink data passes the data logical verification, and may describe whether the to-be-uplink data satisfies the logic satisfied by the data that is not tampered or forged, that is, may describe whether the to-be-uplink data is not tampered or forged.

Correspondingly, the data verification device can compare the at least two acquired data to be uplink, so as to judge whether all the data to be uplink have consistency. Under the condition that it is determined that all the to-be-uplink data are consistent, it can be shown that the to-be-uplink data acquired from the data transmission devices in different blockchain nodes are consistent, and if any to-be-uplink data can mutually verify that no data change occurs in the transmission process of the to-be-uplink data in the data transmission device, no fault or tampering or counterfeiting of the to-be-uplink data occurs in any verification data transmission device.

Further, under the condition that the data to be uplink are determined to have consistency, data logic verification can be performed on any one piece of data to be uplink. Specifically, the logic that the to-be-uplink data meets without being tampered or forged may be predetermined according to the attribute of the service to which the to-be-uplink data belongs, so that the data logic verification is performed on the actually acquired to-be-uplink data according to the logic, and a further specific method for the data logic verification may be determined according to the attribute of the service to which the to-be-uplink data belongs, which is not limited herein. Under the condition that the data to be linked up is determined to meet the logic which is not tampered or forged through the data logic verification, the obtained logic verification result is verification passing; otherwise, the obtained logic verification result is verification failure.

Optionally, the to-be-uplink data may be data belonging to one or more services, and in an optional embodiment of the present invention, the to-be-uplink data may include a service identification identifier, and the data verification apparatus may obtain the to-be-uplink data corresponding to the same service according to the service identification identifier, and perform data logic verification on the part of the to-be-uplink data according to the attribute of the service. Optionally, after the data to be uplink corresponding to the same service is obtained, it may be further verified whether the data to be uplink corresponding to the same service includes all data that the service needs to acquire and store to the block chain network, and if so, data logic verification is performed on the part of the data to be uplink; otherwise, the data to be linked can be continuously acquired until all the data which need to be acquired and stored in the blockchain network of the service is completely acquired.

In an optional embodiment of the present invention, the performing data logic verification on any of the to-be-uplink data may include: acquiring mutual authentication data in the data to be uplink; acquiring preset mutual authentication logic data matched with the mutual authentication data; and performing data logic verification on the mutual verification data according to the preset mutual verification logic data.

Wherein the mutual authentication data may be at least two data that may have a specific logical relationship without being tampered or forged. The preset mutual authentication logical data may be data describing a specific logical relationship between the mutual authentication data without being tampered or falsified.

Correspondingly, according to the specific logical relationship between the to-be-uplink data determined by the service attributes under the condition that the to-be-uplink data is not tampered or forged, the mutual authentication data in the to-be-uplink data and the corresponding preset mutual authentication logical data can be predetermined, and then the mutual authentication data in the to-be-uplink data can be subjected to data logical authentication by acquiring the mutual authentication data and the preset mutual authentication logical data.

For example, in the customer information uplink service of a bank, the data to be uplink may include a pair of mutual authentication data of a birthday and an age of a customer, the corresponding preset mutual authentication logical data may be data describing a relationship between the current time and the birthday data, and the age of the customer may be calculated according to the description of the preset mutual authentication logical data and the birthday data, and compared with the obtained age data, so as to implement mutual authentication between the birthday data and the age data. The data to be linked may further include identity card information data of the client and a pair of mutual authentication data associated with the collected legal filing information data, and the corresponding preset mutual authentication logic data may be data describing a relationship between the identity card information data and the legal filing information data, and the two are compared with each other, so that mutual authentication between the data can also be achieved.

In an optional embodiment of the present invention, the performing data logic verification on any of the to-be-uplink data may include: acquiring preset evidence chain data matched with the data to be linked; and performing data logic verification on the data to be linked according to the preset evidence chain data.

The preset evidence chain data may be data of an evidence chain formed by preset data to be uplink according to the service attribute without being tampered or forged.

Correspondingly, the evidence chain formed under the condition that the data to be uplink is not tampered or forged, which is determined according to the service attribute, can predetermine the preset evidence chain data of the data to be uplink, and then the data logic verification can be performed on the data to be uplink through the description of the preset evidence chain data.

For example, in the above example of the customer information uplink service of the bank, data logic verification may be performed on to-be-uplink data generated by information recorded in a customer money-drawing scenario, specifically, the preset evidence chain data may describe an evidence chain formed by customer identity information card information, customer face information, customer signature information, protocol information and time information required in the money-drawing scenario, so that whether the to-be-uplink data meets the complete logic of the evidence chain may be verified according to the preset evidence chain data.

Optionally, under the condition that it is determined that there is no consistency between any data to be uplink, it is determined that there is a security risk in the data to be uplink, and uplink of the data is ended.

S130, obtaining the logic verification results obtained from all the block chain nodes, and determining the data to be uplink as target uplink data under the condition that all the logic verification results are verified.

The target uplink data may be data to be uplink data, and the data that can be written into each blockchain node of the blockchain network is determined after verification by the data verification device.

Correspondingly, the data verification device in each blockchain node can perform data logic verification on the data to be uplink under the condition that the consistency of all the data to be uplink is determined and obtain a logic verification result, and through the blockchain network, the data verification device in any blockchain node can obtain the logic verification result obtained by the data verification device in all the blockchain nodes. When all the logic verification results are determined to be verified, it can be shown that the data verification device passing through each blockchain node can verify that the to-be-uplink data meets the logic that the to-be-uplink data is not tampered or forged, that is, verify that the to-be-uplink data is not tampered or forged, and therefore, the to-be-uplink data can be determined as the target uplink data to be written into each blockchain node of the blockchain network.

In an optional embodiment of the present invention, after determining the data to be uplink data as target uplink data, the method may further include: and performing encapsulation and packaging processing on all target uplink data corresponding to the same service, and writing the data into each block chain node of the block chain network.

Correspondingly, for all the target uplink data of the same service, the data can be written into the blockchain node after being packaged and packaged, so that the complete data of the service is stored in the blockchain network. Any realizable method may be adopted for the packaging and packaging process, again without limitation.

Optionally, the encapsulating and packaging all the target uplink data corresponding to the same service, and writing the encapsulated and packaged target uplink data into each block chain node of the block chain network may include: and packaging all the target uplink data corresponding to the same service, and writing the data into the formal subarea in each block chain node.

The formal partition may be a storage region in the block link point for storing the target uplink data, and may be a storage region distinguishable from the verification partition. Accordingly, the formal partition may be a storage area previously deployed in the blockchain node, and may be written with data by the data verification apparatus. After all target uplink data corresponding to any service are obtained and encapsulated and packaged, the target uplink data can be written into a formal partition of a block chain node to complete uplink operation of the target uplink data.

Optionally, when the logical verification result obtained by any blockchain node is a verification failure, it is determined that the data to be uplink has a security risk, and the data uplink is ended.

The embodiment of the invention provides a data processing method based on a block chain, which obtains at least two pieces of data to be uplink from data transmission devices deployed in different block chain nodes through a data verification device deployed in a block chain node, and under the condition of determining that all the data to be uplink have consistency, performing data logic verification on the data to be uplink transmitted to obtain a logic verification result of the data to be uplink transmitted, and obtaining logic verification results obtained in all blockchain nodes, determining the data to be uplink as the target uplink data under the condition that all the logic verification results are verified, the method and the device have the advantages that the data uplink is carried out after the security of the data to be uplink is confirmed, the risks that the data are falsified and forged before the data are uplink in the prior art are avoided, the reliability of the data before the data are uplink in the block chain network is ensured, and the data reliability of the whole block chain network is improved.

Example two

Fig. 2 is a flowchart of a data processing method based on a blockchain according to a second embodiment of the present invention, where this embodiment is applicable to a case where data transmission is performed after security of data to be transmitted is confirmed, and the method may be executed by a data transmission apparatus according to a second embodiment of the present invention, where the apparatus may be implemented by software and/or hardware, and may be generally integrated in a computer device, for example, a blockchain node. Accordingly, as shown in fig. 2, the method includes the following operations:

s210, receiving data to be transmitted sent by the target data acquisition device according to the preset binding relationship.

The data acquisition device and the data transmission device can be deployed at the same block chain node point or different block chain nodes, data transmission can be performed between the data acquisition device and the data transmission device, and the data acquisition device can acquire data to be transmitted and send the data to the data transmission device. The preset binding relationship may be a binding relationship between the data acquisition device and the data transmission device that is preset. The data to be transmitted may be data that needs to be transmitted to the data verification device by the data transmission device. It should be noted that the data transmission device and the data verification device in the embodiment of the present invention may respectively implement the methods implemented by the data transmission device and the data verification device in any embodiment of the present invention, and obtain corresponding beneficial effects.

Correspondingly, the data transmission devices and the data acquisition devices deployed in the same or different block link points in the same block chain network may be bound by a preset binding relationship, which may be one-to-one binding or one-to-many binding, and is not limited herein. Optionally, the binding relationship may be established through information such as an IP address and/or a MAC address. After the data acquisition device acquires the data to be transmitted, the data acquisition device can send the data to be transmitted to the data transmission device having a preset binding relationship with the data acquisition device. Therefore, the data transmission device can receive the data to be transmitted sent by the data acquisition device with the preset binding relationship according to the preset binding relationship. The data acquisition device and the data transmission device can confirm the safety of each other in the data transmission process by presetting the binding relationship, and the communication opposite terminal which does not have the preset binding relationship with the data acquisition device does not carry out any data transmission.

Optionally, the data acquisition devices and the data transmission devices deployed in the same blockchain network may have a one-to-one mapping preset binding relationship.

And S220, acquiring the acquired signature data of the data to be transmitted.

Correspondingly, in order to ensure the security of the data to be transmitted in the transmission process between the data acquisition device and the data transmission device, the data acquisition device can add acquisition signature data to the data to be transmitted before sending the data to be transmitted so as to encrypt the data. The specific method for adding the collected signature data to the data to be transmitted may include any realizable digital signature technology, and is not limited herein. The acquired signature data and the data to be transmitted can be sent to the data transmission device together, the data transmission device acquires the acquired signature data of the data to be transmitted, and the acquired signature data can be verified based on the adopted digital signature technology, so that whether the data to be transmitted is tampered in the process of being sent to the data transmission device by the data acquisition device is determined according to the verification result of the acquired signature data.

And S230, adding transmission verification data into the data to be transmitted under the condition that the data to be transmitted is determined to be reliable according to the acquired signature data, and performing transmission signature processing on the data to be transmitted and the transmission verification data to obtain target transmission data.

Wherein the transmission verification data is obtained by the negotiation between the data transmission device and the data verification device. The transmission signature process may be an operation of adding transmission signature data to data.

Correspondingly, if the data transmission device can determine that the data to be transmitted is not tampered according to the acquired signature data, that is, the data to be transmitted is determined to be reliable, the data transmission device can further process the data to be transmitted so as to generate target transmission data according to the data to be transmitted and send the target transmission data to the data verification device. Specifically, according to negotiation with the data acquisition device, the data transmission device may acquire transmission verification data and add the transmission verification data to the data to be transmitted, and further, perform transmission signature processing on the data to be transmitted and the transmission verification device to generate transmission signature data that can be verified by the data verification device in the data to be transmitted, thereby obtaining target transmission data.

And S240, sending the target transmission data to data verification devices of all the block chain nodes.

Correspondingly, the data transmission device can send the target transmission data to the data verification device, so that after the data verification device receives the target transmission data, the data transmission device can verify the safety of the target transmission data in the process of sending the target transmission data to the data verification device according to the transmission signature data and the transmission verification data of the target transmission data, and after the safety of the target transmission data is determined, the data to be linked is obtained through the target transmission data.
