To make the objects, technical solutions and advantages of one or more embodiments of the present disclosure more apparent, the technical solutions of one or more embodiments of the present disclosure will be described in detail and completely with reference to the specific embodiments of the present disclosure and the accompanying drawings. It is to be understood that the embodiments described are only a few embodiments of the present specification, and not all embodiments. All other embodiments that can be derived by a person skilled in the art from the embodiments given herein without making any creative effort fall within the scope of protection of one or more embodiments of the present specification.
The technical solutions provided by the embodiments of the present description are described in detail below with reference to the accompanying drawings.
In the prior art, a data provider generally needs to provide data required by a data demander to the data demander, and self-certify the credibility of the data presented by the data demander, and enable the data demander to verify the credibility of the data provided by the data provider. Therefore, the data provider usually obtains the data with the authority official seal and feeds back the data with the authority official seal as the credible data to the data demand side. And the data demand party needs to feed back the acquired data with the authority official seal to the authority for credibility verification. Therefore, the credible data processing method is poor in use convenience.
In order to solve the defects in the prior art, the scheme provides the following embodiments:
fig. 1 is a schematic flowchart of a trusted data processing method according to an embodiment of the present disclosure. From a program perspective, the execution subject of the flow may be a trusted data processing application of a data provider or a device on which the trusted data processing application is installed.
As shown in fig. 1, the process may include the following steps:
step 102: acquiring data demand information; the data demand information is used for requesting to acquire target data of a data provider.
In this specification, a trusted data processing application of a data provider may obtain data requirement information for target data of the data provider. In practical applications, the data requirement information may be generated according to a data acquisition requirement of a data demanding party, or may be generated according to a data acquisition requirement of a data providing party, or may be generated by a trusted data processing application according to a preset data acquisition rule, which is not specifically limited.
Step 104: acquiring the target data according to the data demand information; the target data is data collected by the trusted data processing application from the data provider as a target client of a user.
In this embodiment of the present specification, a trusted data processing application and a target client are generally installed on a device of a data provider, and since the data requirement information may indicate that an information source of the target data is the target client, the trusted data processing application may obtain the target data from the target client used by the data provider according to the data requirement information.
Specifically, step 104: the obtaining the target data according to the data requirement information may include: and the trusted data processing application acquires the target data from the data generated in the process of using the target client by the data provider according to the data demand information.
In this specification embodiment, the data generated by the data provider in the process of using the target client may include: the data input by the data provider at the application interface of the target client, the data displayed by the application interface of the target client, and the data downloaded locally by the data provider from the target client are not particularly limited.
Step 106: and encrypting the target data to obtain encrypted target data.
In the embodiment of the present specification, the target data acquired by the trusted data processing application may be encrypted by using an existing encryption processing mode to obtain encrypted target data, which is not described in detail herein.
Step 108: generating a trusted identifier for the encrypted target data to obtain trusted encrypted data, wherein the trusted encrypted data is the encrypted target data carrying the trusted identifier.
In this embodiment of the present specification, the trusted data processing application may further generate a trusted identifier for the encrypted target data, so as to obtain the encrypted target data carrying the trusted identifier. The trusted identifier may carry data source information and acquisition time information of the encrypted target data, and may also indicate that the encrypted target data is trusted data, that is, the trusted identifier may also indicate that the encrypted target data is true and complete and has not been tampered. Therefore, after the data demand party receives the encrypted target data carrying the trusted identification, the data demand party can know that the encrypted target data is the trusted data collected from the target client at x days x in x years.
In the method shown in fig. 1, the trusted data processing application can automatically generate trusted encrypted data with high reliability based on the operation performed by the data provider when the data provider normally uses the target client, and does not need the data provider to additionally perform trusted data acquisition operation, so that the operation process of the data provider for acquiring trusted data can be simplified, and the convenience in use of the trusted data acquisition scheme can be improved. And because the trusted encrypted data generated by the trusted data processing application is ciphertext data, the leakage of the original data of the user in the use process of the trusted encrypted data can be avoided, and the data security and privacy of the data provider can be improved. And the data demand party receives the credible encrypted data carrying the credible identification, so that the data demand party can conveniently determine the credibility of the credible encrypted data according to the credible identification.
Based on the process in fig. 1, some specific embodiments of the process are also provided in the examples of this specification, which are described below.
Step 102: acquiring data requirement information may specifically include:
and acquiring a target data acquisition request sent by a data demander through a first blockchain network, wherein the target data acquisition request is used for requesting to acquire target data of a data provider.
In the embodiments of the present disclosure, the data provider and the data demander may perform data flow based on the blockchain technique. The Block chain (Block chain) may be understood as a data chain formed by sequentially storing a plurality of blocks, and a Block header of each Block includes a time stamp of the Block, a hash value of previous Block information, and a hash value of the Block information, thereby implementing mutual authentication between the blocks and forming a non-falsifiable Block chain. Each block can be understood as a data block (unit of storage data). The block chain as a decentralized database is a series of data blocks generated by correlating with each other by using a cryptographic method, and each data block contains information of one network transaction, which is used for verifying the validity (anti-counterfeiting) of the information and generating the next block. The block chain is formed by connecting the blocks end to end. If the data in the block needs to be modified, the contents of all blocks after the block need to be modified, and the data backed up by all nodes in the block chain network needs to be modified. Therefore, the blockchain has the characteristic of being difficult to tamper and delete, and the blockchain has reliability as a method for keeping the integrity of the content after the data is stored in the blockchain.
In the embodiments of the present disclosure, a distributed digital identity service may be provided through a blockchain platform, so that a data provider and a data demander may perform data streaming based on respective distributed digital identities. In practical applications, both the data provider and the data demander may request a Distributed Identity Service (DIS) to create a distributed Digital Identities (DID) of the individual. The DIS is an identity management scheme based on a block chain, and a DIS server can be connected with a block chain platform and provides functions of digital identity creation, verification, management and the like, so that entity data can be managed and protected in a standardized mode, authenticity and efficiency of information transfer are guaranteed, and the problems of cross-organization identity authentication, data cooperation and the like can be solved.
In this embodiment, both the data demander and the data provider may register a personal DID in advance, so as to implement data streaming based on the personal DID. Specifically, the data demander may generate a target data obtaining request based on the data demander DID, where the target data obtaining request may indicate that a user corresponding to the data demander DID requests to obtain target data of a user corresponding to the data provider DID.
In this specification embodiment, the trusted data processing application of the data provider may be communicatively connected to the first blockchain network, so that the data provider may receive, through the trusted data processing application, a target data acquisition request of the data consumer for the data provider DID. The data provider may also perform authorization management on a target data obtaining request sent by the data demander through the trusted data processing application, for example, the data provider may generate an authorization instruction by operating the trusted data processing application, so as to instruct the data demander to be allowed to obtain the target data; or, the data provider can also generate a refusal authorization instruction by operating the trusted data processing application, so as to indicate a refusal data demand party to acquire the target data; so that the data provider can conveniently and authorized manage the personal data through the trusted data processing application.
Correspondingly, the trusted data processing application may obtain the target data according to the data requirement information after obtaining the authorization instruction of the data provider for the target data obtaining request. If the trusted data processing application acquires the denial authorization instruction of the data provider for the target data acquisition request, the trusted data processing application may jump to the end step without executing the step of acquiring the target data.
Of course, the data provider may also perform authorization management for the target data acquisition request sent by the data demander by logging in the device with the personal blockchain account, and the trusted data processing application may be in communication connection with the device. And when the trusted data processing application receives an authorization instruction sent by the equipment, acquiring the target data according to the data demand information. So that the data provider can manage the use authority of the personal data.
Alternatively, the data consumer may send the target data acquisition request to the trusted data processing application of the data provider in a chain-down manner (i.e., a manner that does not employ the blockchain technique), which is not particularly limited.
In the embodiment of the present disclosure, to ensure the security and traceability of the data transmission process, the data of the data provider may be transmitted to the data demander by using the blockchain network.
Thus, step 108: generating a trusted identifier for the encrypted target data, and after obtaining trusted encrypted data, the method may further include: and the trusted data processing application sends the trusted encrypted data to the data demand party through a second blockchain network.
In this embodiment of the present specification, the second blockchain network may be the same blockchain network as the first blockchain network, or may be a different blockchain network, which is not particularly limited.
Certainly, the trusted data processing application may also send the trusted encrypted data to the data requesting party in a linked-down manner, and since the trusted encrypted data is ciphertext data, when the trusted encrypted data is transmitted by using various transmission methods, the security and privacy of the original data of the data providing party can be protected.
In the embodiment of the present specification, the data demander may need to acquire target data from the data provider to execute a specified service based on the acquired target data. For example, when a data provider needs to transact a financial transaction at a data demander, the data demander may need to obtain banking data of the data provider. Alternatively, when a data provider needs to obtain a promotion service at a data demander, the data demander may need to obtain customer order data of the data provider on a specified commerce platform. Or, when the data demander needs to complete the analysis demand for the passenger flow volume data in the business platform, the data demander may need to acquire the passenger flow data of the data provider in each time period on the business platform, and the like.
As can be seen, the data sources of the target data that need to be collected by the trusted data processing application are not completely consistent for different data requirements. Based on this, the target data obtaining request sent by the data demanding party may also indicate that the data source of the target data is the target application client, that is, the data demanding information may indicate that the data source of the target data of the data providing party should be the target client.
In practical applications, the target client may be in various types, such as a business application client, a search engine client, an instant messaging application client, a network media application client, and the like. The various target clients can be realized by Web Technology (Web Technology) or Application software (Application) Technology.
When the target client is a target Web page client implemented based on Web technology, the trusted data processing application may be a Plug-in (also called add-in, or add-on) that is loaded at the target Web page client.
The acquiring of the target data from the data generated in the process of using the target client by the data provider may specifically include the following various implementation manners.
Implementation mode one
The trusted data processing application may collect the target data from web page data browsed by the data provider at the target web page client.
In an embodiment of the present specification, a data provider may automatically run an available plug-in (e.g., a trusted data processing application) of the target web client after starting the target web client. The trusted data processing application can collect the target data from the webpage data browsed by the data provider in the process that the data provider normally uses the target webpage client to browse the webpage data.
Specifically, a communication protocol may be pre-signed between the trusted data processing application and the target web client, so that the trusted data processing application may obtain all web data displayed on the current page of the target web client, and thus may extract the target data from all web data displayed on the current page of the target web client according to the data demand information.
Implementation mode two
The trusted data processing application may collect the target data from web page data downloaded by the data provider at the target web page client.
In this embodiment of the present disclosure, based on the same principle as the first implementation, the trusted data processing application may collect the target data from the web page data downloaded locally from the data provider after the data provider normally uses the target web page client to download the web page data.
In the first implementation manner and the second implementation manner, when the trusted data processing application is used for acquiring target data, the data provider can perform non-perception acquisition, that is, the data provider only needs to perform operations such as browsing and data downloading on the target webpage client according to the existing operation regulations of the target webpage client, and does not need to additionally perform specified operations to acquire the trusted data, so that the operation convenience of acquiring the trusted data by the data provider is improved.
And the trusted data processing application can acquire the trusted data by performing data interaction with the target client, and does not need to perform data communication between the trusted data processing application and the server of the target client, so that not only can the equipment resources required to be consumed during the acquisition of the trusted data be reduced, but also the steps required to be executed by the server of the target client can be reduced, and the trusted data acquisition process can be simplified.
In this specification, the target data may be personal business data of a data provider, such as bank flow data, business order data, and the like, so that the data provider needs to log in a registered account of an individual at a target web client to browse or download the target data from the target web client, and as a result, the target data may be user business data having a corresponding relationship with the registered account of the data provider at the target client.
Alternatively, the target data may be public data having a browsing or downloading right of the data provider, such as news information, a user blog, and the like, in which case, the data provider may browse or download the target data from the target web client without logging in a registered account of an individual, and it is obvious that the target data may also be data having no correspondence with the registered account that the data provider logs in at the target client.
In practical applications, the type of the target data may be various, for example, at least one of a designated field in the web page data, a designated picture in the web page data, and a designated multimedia file in the web page data, which is not particularly limited.
When the target client is a target APP client implemented based on Application Software (Application), the trusted data processing Application may be an available Software Development Kit (SDK) loaded at the target APP client or another APP Application client communicatively connected to the target APP client.
Correspondingly, when the data provider starts the target APP client, an available software development kit (e.g., a trusted data processing application) loaded at the target APP client may be automatically run; or, the trusted data processing application may monitor whether the target APP client is in a running state; therefore, the trusted data processing application can acquire the target data from the data displayed by the application interface of the target APP client or from the data downloaded by the target APP client by the data provider in the process that the data provider normally uses the target APP client.
In this embodiment of the present specification, after the trusted data processing application collects target data, trusted encryption data may be generated according to the target data. Different data demanders may have the acquisition requirements for the same target data, or the trusted data processing application may need to send the target data to the data demanders after a specified time period. Thus, the trusted data processing application may store the generated trusted encrypted data for subsequent operations.
Thus, step 108: generating a trusted identifier for the encrypted target data, and after obtaining trusted encrypted data, the method may further include: and storing the trusted encryption data to trusted hardware.
The Trusted hardware is one of important bases of Trusted computing, and a Trusted Execution environment (Trusted Execution Environments) can be constructed on the hardware device based on the Trusted hardware, so as to protect program codes and data in the Trusted hardware from being disclosed and modified, and further protect privacy and security of the data in the Trusted hardware. There are various types of trusted hardware, such as trusted chips like SGX, ARM Trust Zone of intel. In the embodiments of the present specification, the specific model used by the trusted hardware is not particularly limited.
In practical applications, the trusted hardware may be a trusted hardware connected to a device on which the trusted data processing application is installed; that is, when trusted hardware is loaded on a device of a data provider, the trusted data processing application may store the trusted encrypted data in the trusted hardware at the device of the data provider.
Alternatively, the trusted hardware may also be trusted hardware connected to the target server. The target server may be a cloud server communicatively coupled to the trusted data processing application. The data provider can request to acquire the use authority of the trusted hardware from the cloud server in advance, so that the data provider can store the trusted encryption data into the trusted hardware outside the device of the data provider through the trusted data processing application, and the configuration requirement of the device of the data provider is reduced.
In the embodiment of the specification, because the trusted data processing application can pre-store part of trusted data of the data provider into the trusted hardware, the trusted data processing application can acquire the target data from the data stored in the trusted hardware according to the data demand information, and does not need to acquire the target data based on the data generated by the data provider operating the target client at present, which is beneficial to improving the real-time performance of target data acquisition.
In this embodiment of the present specification, after the data demander obtains the trusted encrypted data, there may be a need to verify the trustworthiness of the trusted encrypted data, so that, in step 108: generating a trusted identifier for the encrypted target data, and after obtaining trusted encrypted data, the method may further include: and storing the trusted encryption data to a third blockchain network.
The third blockchain network and the first blockchain network and the second blockchain network may be the same blockchain network or different blockchain networks, which is not limited in particular.
In this embodiment of the specification, the trusted encryption data stored in the third block chain network may be subsequently used as reference data to perform consistency comparison on the trusted encryption data acquired by the data demander, so as to complete the credibility verification on the trusted encryption data acquired by the data demander.
Fig. 2 is a schematic flowchart of a trusted data acquisition method according to an embodiment of the present disclosure. From a procedural point of view, the execution subject of the method may be a device of a data consumer.
As shown in fig. 2, the process may include the following steps:
step 202: and acquiring the operation information of the data demand side.
Step 204: and generating a target data acquisition request according to the operation information, wherein the target data acquisition request is used for requesting to acquire target data of a data provider.
In the embodiment of the present specification, the data demander may request to obtain the target data based on the block chain technique. The data consumer may perform a trigger operation for the blockchain application on the data consumer's device to generate a target data acquisition request for requesting target data from the data provider. Alternatively, the data demander may request to acquire the target data based on a technique other than the blockchain, and the data demander may perform a trigger operation for a non-blockchain application on the device of the data demander, so as to generate a target data acquisition request for requesting to acquire the target data of the data provider, which is not limited in particular.
Step 206: and sending the target data acquisition request.
In this embodiment of the present specification, the data demander may send the target data acquisition request to the data provider through the first blockchain network, or may send the target data acquisition request to the data provider through a downlink transmission manner, which is not specifically limited, and only needs to enable the trusted data processing application of the data provider to acquire the target data acquisition request.
Step 208: receiving trusted encryption data fed back by the data provider; the trusted encryption data is encryption target data which is generated by trusted data processing application of the data provider and carries a trusted identifier; the encrypted target data is ciphertext data obtained by the trusted data processing application encrypting the target data collected from a target client that is a user from the data provider.
In this embodiment of the present specification, the data provider may use the method shown in fig. 1 to generate the trusted encrypted data that is fed back to the data demander, and details of the generation process of the trusted encrypted data are not repeated.
In practical applications, in order to improve the security and traceability of data transmission, the trusted encryption data may be transmitted in a chain data transmission manner, so that step 208 specifically includes: and receiving the trusted encryption data fed back by the data provider through the second blockchain network. Of course, the data consumer may also receive the trusted encrypted data fed back by the data provider based on the downlink data transmission manner, which is not particularly limited.
In the method shown in fig. 2, the trusted encrypted data fed back by the data provider is the encrypted target data which is generated by the trusted data processing application of the data provider and carries the trusted identifier, so that the data demanding party can determine that the credibility of the trusted encrypted data is high based on the trusted identifier carried by the data demanding party after the data demanding party acquires the trusted encrypted data, and the method is favorable for improving the convenience of the data demanding party in verifying the credibility of the data acquired from the data provider.
In this embodiment of the present specification, in addition to verifying the credibility of the obtained trusted encrypted data according to the trusted identifier, the data demander may also have a need to further verify the credibility of the obtained trusted encrypted data.
Thus, step 208: after receiving the trusted encrypted data fed back by the data provider, the method may further include: and carrying out credible verification on the credible encrypted data by using the credible data processing application of the data demand party to obtain a verification result.
Specifically, the data demander may obtain the reference data from the third blockchain network by using a trusted data processing application of the data demander; and the reference data is ciphertext data which is sent to the third block chain network for storage and carries the trusted identification by the trusted data processing application of the data provider.
The consistency of the reference data and the credible encrypted data is verified, and if the reference data is consistent with the credible encrypted data, a verification result indicating that the credible encrypted data received by a data demand party is credible and not tampered can be generated; and if the reference data is inconsistent with the trusted encrypted data, a verification result indicating that the trusted encrypted data received by the data demand party is not trusted and has a risk of being tampered can be generated.
In this embodiment of the present specification, since the ciphertext data carrying the trusted identifier and stored at the third block chain network is generated by the trusted data processing application of the data provider and stored at the third block chain network, the data carrying the trusted identifier and stored at the third block chain network is trusted data and can be used as reference data. And because the data carrying the trusted identification stored at the third block chain network is ciphertext data, the security and privacy of the original data of the data provider can be ensured.

The embodiments in the present specification are described in a progressive manner, and the same and similar parts among the embodiments are referred to each other, and each embodiment focuses on the differences from the other embodiments. In particular, as for the apparatuses shown in fig. 5 and 6, since they are substantially similar to the method embodiments, the description is simple, and the relevant points can be referred to the partial description of the method embodiments.
In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital character system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate a dedicated integrated circuit chip. Furthermore, nowadays, instead of manually making an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Hardware Description Language), traffic, pl (core universal Programming Language), HDCal (jhdware Description Language), lang, Lola, HDL, laspam, hardward Description Language (vhr Description Language), vhal (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: the ARC625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.
The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions. One typical implementation device is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smartphone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.
