Detailed Description
First, before the present application is introduced, the relevant contents of the present application with respect to the application background will be described.
The transaction data processing method, the transaction data processing device and the computer readable storage medium can be applied to a transaction data processing system, when the transaction data processing method and the device are applied to a block chain platform, sensitive word filtering processing can be uniformly carried out on the transaction data through specific second block chain node equipment in the block chain platform, the sensitive word filtering requirement of the block chain platform is met, meanwhile, a sensitive word filtering strategy can be conveniently maintained at the second block chain node equipment, the maintenance cost is low, and the transaction data processing method and the device have good practical value.
The execution main body of the transaction data processing method can be a transaction data processing device, or a transaction data processing system integrated with the transaction data processing device, and the system can include different types of block link point devices such as a server device, a physical host, or a User Equipment (UE), wherein the transaction data processing device can be implemented in a hardware or software manner, and the UE can be a terminal device such as a smart phone, a tablet computer, a notebook computer, a palm computer, a desktop computer, or a Personal Digital Assistant (PDA).
Next, a description will be given of a transaction data processing method provided in the present application.
First, referring to a scene schematic diagram of a processing method of transaction data of the present application shown in fig. 1 and a flow schematic diagram of a processing method of transaction data of the present application shown in fig. 2, as shown in fig. 2, the processing method of transaction data provided by the present application may specifically include the following steps:
step S201, a first block chain link point device acquires target transaction data in a block chain platform;
step S202, the first block chain link point device transmits target transaction data to a second block chain link point device preset in a block chain platform, wherein the second block chain link point device is a block chain link point device with a sensitive word filtering strategy deployed;
step S203, the second block node device invokes a sensitive word filtering policy to perform sensitive word filtering processing on the target transaction data.
As can be seen from the embodiment shown in fig. 2, when the blockchain platform has a requirement for filtering sensitive words, the application proposes to select a specific second blockchain node point device in the blockchain platform, and when the first blockchain node point device in the blockchain platform acquires target transaction data to be subjected to sensitive word filtering processing, the target transaction data can be sent to the second blockchain node point device, and the second blockchain node point device performs sensitive word filtering processing on the transaction data in a unified manner.
In addition, since the sensitive word filtering strategy is deployed in the second blockchain node device, a targeted security protection strategy is also easier to deploy, and higher data security can be achieved in the case of implementing the sensitive word filtering by the blockchain platform.
The following describes each step in the embodiment shown in fig. 2 and a specific implementation manner that may be adopted in practical applications of each step.
In the Application, different types of devices, such as a server device, a physical host, or a UE, may install an Application (APP) on a block chain platform, register an account, and after passing through verification of the platform, add the platform to become a block chain node device.
In practical applications, the uplink request may be a request initiated by the node equipment of the block chain. Such as transaction request, information with storage needs to be uplink for storage, calculation and other corresponding processing in the blockchain platform
Alternatively, the uplink request may be a request initiated by another device through a block-node device. For example, if a device wants to join a blockchain platform, a blockchain joining request may be forwarded to the platform through a blockchain link point device already joined to the platform, and after the platform passes through, the device may be pulled into the platform to become a new blockchain link point device.
For the data related to the uplink request, it may be referred to as transaction data, in other words, the transaction data for which the present application is directed may be the transaction data requested by the uplink request, and correspondingly, the acquiring, by the first bsp device, the target transaction data may include:
the first blockchain link point equipment acquires an uplink request, wherein the uplink request is used for requesting to uplink target transaction data to the blockchain platform; the first blocklink point device extracts target transaction data according to the uplink request.
It is easy to understand that, in practical applications, the sensitive word filtering processing can be performed on the transaction data that needs to be linked up by default corresponding to the sensitive word filtering requirement of the blockchain platform, so that the obtained transaction data pointed by the link up request can be used as target transaction data and sent to the second blockchain link point device for performing unified sensitive word filtering processing.
In addition, in practical applications, the transaction data targeted by the present application may also be data that has been linked in the blockchain platform, that is, target transaction data acquired by the first blockchain link point device, and data that has been linked in the blockchain platform in a historical time period.
It should be understood that, in practical applications, the stored data related to the blockchain may be understood as transaction data processed in a transaction form according to the service requirements of the actual applications, and the uplink of the transaction data may be specifically performed through a consensus mechanism in the blockchain platform, when the transaction data has uplink requirements, the transaction data may be sent to each blockchain node, and each blockchain node device votes whether to uplink the transaction data under the specification of the consensus mechanism, and when the voting result meets the passing requirement specified by the consensus mechanism, the uplink of the data may be implemented.
For example, in the application of the present application, after the first block link point device obtains the target transaction data, if the target transaction data is the transaction data to be linked, before performing the consensus, the target transaction data may be sent to the second block link point device to perform the sensitive word filtering process, and after the sensitive word filtering process of the second block link point device is performed, the consensus is performed to complete the data linking. Of course, in practical applications, it may also happen that the sensitive word filtering process is performed during the consensus process.
If the transaction data has been processed by filtering the sensitive words of the second block node device, a filtering identifier may be assigned to identify whether the transaction data has been processed by filtering the sensitive words of the second block node device, and through the identifier, whether the transaction data still needs to be processed by filtering the sensitive words may be clearly and easily learned.
For example, if it is detected that the acquired historical transaction data does not carry a filtering identifier, the acquired historical transaction data can be used as current target transaction data and sent to second block link point equipment for sensitive word filtering processing; or, if it is detected that the identification content of the filtering identification of the acquired historical transaction data does not pass the sensitive word filtering processing, the identification content may be sent to the second block link point device for sensitive word filtering processing, and may be specifically adjusted according to the identification form of the filtering identification, which is not specifically limited herein.
Correspondingly, when the sensitive word filtering is identified by whether the filtering identification is carried, in order to match with the unified identification processing, when the transaction data which is not subjected to the common identification or not subjected to the uplink is taken as the target transaction data, the field position of the preset filtering identification can be configured to be empty content so as to definitely identify that the transaction data does not pass the sensitive word filtering processing. Or; when the sensitive word filtering processing is specifically identified by filtering the identification content of the identification, in order to match with the unified identification processing, the identification content of the filtering identification can be given to the transaction data which is not subjected to common identification or uplink transmission, and then the transaction data is taken as the target transaction data, so as to definitely identify that the transaction data does not pass the sensitive word filtering processing.
In addition, in practical applications, especially for historical transaction data, if an update event occurs in the sensitive word filtering process, it is easy to understand that the original data content filtered by the sensitive word may need to continue the sensitive word filtering process to filter the content that needs to be filtered now, such as the above filtering identifier, and specifically, the identifier time point or the sensitive word filtering policy version may also be identified to determine whether the sensitive word policy passed by the sensitive word filtering process is performed under a new or old sensitive word filtering policy.
For example, for the above two types of transaction data proposed above, that is, the transaction data that does not complete uplink and the historical transaction data that has completed uplink, in a specific practical application, there may be a case that the update of the sensitive word filtering policy is currently triggered, it is easy to understand that after the update of the sensitive word filtering policy, there is a new sensitive word filtering process performed on the historical transaction data that completes uplink, and for the transaction data that does not complete uplink, it is obvious that the filtering process may still be performed according to normal sensitive words.
It should be noted that, in practical applications, there may be a huge amount of transaction data processed by the blockchain platform in a short time, and there may be a delay of a certain time when the sensitive word filtering policy is updated, and there may be some special cases, for example, a small amount of transaction data temporarily stops the sensitive word filtering processing, and accumulates into historical transaction data that is not subjected to the sensitive word filtering processing, or a small amount of transaction data passes through the sensitive word filtering processing of the original sensitive word filtering policy within the update time, so the present application specifically addresses a specific acquisition mode of target transaction data for a small amount of abnormal transaction data caused by the updating of the sensitive word filtering policy, that is:
and when the sensitive word filtering strategy is detected to be updated, triggering and acquiring the transaction data of the block chain platform in the historical time period before updating as target transaction data.
It can be understood that, specifically, the update time point when the sensitive word filtering policy is updated may be used to obtain the transaction data of the data time point in the historical time period before the update time point, as the target transaction data currently subjected to the sensitive word filtering processing under the new sensitive word filtering policy, so that it may be ensured that the transaction data that has been historically linked up and has passed through the original sensitive word filtering processing, or the transaction data that has been historically linked up and has not passed through the original sensitive word filtering processing, or the transaction data that has not been linked up and has not passed through the original sensitive word filtering processing, may be accurately captured, and may be used as the target transaction data to be subjected to the sensitive word filtering processing under the new sensitive word filtering policy. And for the updated new transaction data to be linked, the sensitive word filtering processing under the new sensitive word filtering strategy can be normally carried out.
Generally, the update time point of the sensitive word filtering policy is specifically the time point when the update is completed, or may be the time point when the update is triggered.
As a practical implementation manner, referring to a flow diagram of the traversal scanning process of the target transaction data shown in fig. 3, the processing content may specifically include the following steps S301 to S303:
step S301, the first block chain node equipment determines an update time point of a sensitive word filtering strategy;
the first blockchain node may extract an update time point of the sensitive word filtering policy, such as the above-mentioned time point of completing the update, or a time point when the update is triggered.
Specifically, the required update time point may be extracted from event data, such as a log, generated when the sensitive word filtering policy executes the update event.
Step S302, the first block chain node equipment identifies and updates the block height S matched with the time point from the block to be scanned;
in the present application, the blocks in the blockchain platform are similar to the list in terms of the scanning manner of the device, and the data time points of the blocks are arranged from bottom to top, the lower the block is, the longer the time span between the block and the current time point is, and conversely, the block on the upper layer is, the shorter the time span between the block and the current time point is.
In this case, the present application first identifies a block having a data time point that is the same as or closest to an update time point of the sensitive word filtering policy from among blocks within the scanning range, and records a block height of the block as a block height s.
It is understood that the block height s is constant in one scanning period.
Step S303, ignoring the block with the block height greater than the block height S, the first block link point device obtains the transaction data in the block with the block height less than the block height S as the target transaction data, and in each step of obtaining, updates the currently traversed block height e, and uses the transaction data in the block with the block height less than the block height e as the new target transaction data.
After the block height s is obtained, dynamic block scanning is performed by taking the block height s as a reference, each layer of blocks is scanned downwards layer by layer from the blocks smaller than the block height s, and only the transaction data in the blocks smaller than the block height e is taken as target transaction data by combining the dynamically updated currently traversed block height e, and sensitive word filtering processing is performed by a second block link node device.
Or, starting from the block smaller than the block height s, scanning each layer of blocks layer by layer upwards, and only using the transaction data in the block smaller than the block height e as the target transaction data by combining the dynamically updated currently traversed block height e, and executing sensitive word filtering processing by the second block link point device.
It can be understood that, by the scanning mechanism, transaction data in a block with a block height smaller than the block height e, that is, transaction data that does not pass through the sensitive word filtering process under the latest sensitive word filtering policy, is dynamically updated, and new sensitive word filtering process is performed on the transaction data that does not pass through the sensitive word filtering process under the latest sensitive word filtering policy, so that effective filtering process on historical transaction data is ensured within a minimum and effective scanning range.
Secondly, the scanning mechanism implemented based on the block height introduced by the application has the characteristics of simplicity and high efficiency in data processing, so that the efficient scanning efficiency can be provided under the condition of ensuring effective scanning, and the method is suitable for practical use.
It can be understood that in the present application, the sensitive word filtering process, a specific processing manner thereof, except for performing processes such as ignoring, deleting, isolating and the like on the transaction data itself containing the sensitive word, may also directly perform the processing on the sensitive word contained in the transaction data so as to achieve an effect of retaining data contents in the transaction data except for the sensitive word that needs to be filtered, and only filter the sensitive word detected in the transaction data, for example, the sensitive word may be deleted, covered, added with an invalid identifier and the like in the transaction data, so as to achieve an effect of clearing or invalidating the sensitive word.
The sensitive word filtering policy that the sensitive word filtering process depends on is a set of policies required for implementing the sensitive word filtering process, such as an address of a sensitive word bank, a calling mode of the sensitive word bank, a determining mode of a sensitive word, a processing mode of the sensitive word, and the like.
In the present application, the second blockchain link point device selected from the blockchain platform, which is specifically used for performing the sensitive word filtering process, may be selected in advance by a worker of the blockchain platform, or may be selected by voting by a user behind each blockchain link point device in the blockchain platform, in other words, may be selected by manual operation; or, the block chain platform may select the block chain link point device with higher data processing capability as the second block chain link point device, may select the block chain link point device with better network environment as the second block chain link point device, may select the block chain link point device randomly as the second block chain link point device, and may select a new block chain link point device as the second block chain link point device at regular time according to the device identified in the round-robin table. It can be seen that the specific selection strategy of the second block link point device can be adjusted according to actual needs, and the flexibility is high.
In addition, in order to provide convenience for maintenance of the sensitive word filtering strategy, in practical application, an application scheme can be considered, namely a sensitive word library related to the sensitive word filtering strategy is deployed in a pluggable mode.
The sensitive word library can be understood as a set which records various sensitive words needing to be filtered, the set needs to be configured by combining with actual filtering requirements, and therefore updating is needed irregularly along with the lengthening of application time so as to meet the latest sensitive word filtering requirements.
In the basic application scheme, the sensitive word stock can be integrally deployed in an intelligent contract along with a sensitive word filtering strategy, and the sensitive word stock to be called can be extracted from the intelligent contract identified by each node device when the sensitive word filtering strategy is operated.
It can be understood that if the sensitive thesaurus is integrated into the intelligent contract, obviously, each time the sensitive thesaurus is updated, a new round of consensus and writing operation into the intelligent contract are faced.
The method and the system are combined with efficient updating requirements in practical application, and a pluggable scheme is configured, namely the sensitive word stock is stripped out of an intelligent contract, interface data of the sensitive word stock is stored in the intelligent contract, and when the intelligent contract is called and sensitive word filtering processing is executed through a sensitive word filtering strategy, the sensitive word stock can be called through the commonly recognized interface data stored in the intelligent contract.
It is understood that the external sensitive thesaurus is also commonly known, and only the specific sensitive word data in the external sensitive thesaurus can be flexibly and conveniently updated outside, in this case, the external sensitive thesaurus is generally arranged on a device which is beyond the intelligent contract and is considered to have high data security, for example, the external sensitive thesaurus can be specifically deployed on a second block link point device, a first block link point device or even a third party device.
Meanwhile, in order to further improve the sensitive word filtering effect, a layer of simple filtering means can be constructed besides the sensitive word filtering strategy so as to screen the data scale of the transaction data needing to invoke the sensitive word filtering strategy.
Specifically, the filtering means may be understood as a preprocessing means to preliminarily filter the transaction data that does not need to invoke the sensitive word filtering policy and perform the sensitive word filtering processing, or preliminarily filter the transaction data that inevitably needs to be cleared by the general filtering means.
For example, the method can be implemented by combining a blacklist, and the blacklist can be understood as blocking transaction data types needing to be blocked, namely sensitive words do not need to be sent to second block link point equipment for filtering, so that the sensitive words can be directly cleared, invalidated and ignored, and the effect of primary screening is achieved.
Specifically, the data content, the data initiator, the data time point, the data type and the like can be limited, so that the purpose of preliminary screening can be achieved, and the method can be specifically adjusted according to actual needs.
Correspondingly, the target transaction data processed by the second block link point device may specifically correspond to two scenarios:
when the first block chain node equipment detects that the target transaction data does not belong to the transaction data of the blacklist, transmitting the target transaction data to the second block chain node equipment;
or when the second block chain node device detects that the target transaction data does not belong to the transaction data of the blacklist, calling a sensitive word filtering strategy and executing sensitive word filtering processing on the target transaction data.
It is to be understood that this preliminary screening process in combination with the black list may be performed by the first block-linked dot device as well as by the second block-linked dot device.
The blacklist may be configured locally for the blockchain node device, or may be common in the blockchain platform.
