[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] At present, the database watermark technology based on relational data is basically centered between databases, and it is impossible to embed and extract watermarks for dynamic traffic data of interface types. In addition, database watermarks are usually aimed at migration and synchronization between databases, which is not friendly enough for data embedding and extraction in incremental situations. It is necessary to perform the task of embedding database watermarks manually or in a polling manner to achieve the effect of adding watermarks. To this end, the present application provides a database watermark embedding and extraction solution that can improve the efficiency and flexibility of watermark embedding and extraction and save human resources.

[0041] See also Figure 1 As shown, the embodiment of the present invention discloses a database watermark embedding and extraction method, including:

[0042] Step S11: When the to-be-processed business traffic data sent by the corresponding data sender is received through the preset relational database, the corresponding business system integration operation is triggered.

[0043] Specifically, in this embodiment, combined with the Figure 2 As shown, after the data generated and sent by the data sender is received through the preset relational database, business system integration needs to be performed first. That is, when the pending business traffic data sent by the corresponding data sender is received through the preset relational database, the corresponding business system integration operation is triggered, including: when the pending business traffic data sent by the corresponding data sender is received through the preset relational database, the local watermark SDK (Software Development Kit) is integrated into the target business system that processes the pending business traffic data. That is, this embodiment integrates the watermark SDK into the corresponding business system for internal interface calls of the business system. In this way, watermark embedding and extraction can be selectively performed on specific business data according to specific business scenarios. Among them, the data sender includes but is not limited to government affairs systems.

[0044] Step S12: calling the watermark SDK in the preset relational database through the preset calling interface in the integrated target business system, and embedding the watermark into the business traffic data to be processed using the corresponding watermark parameters and the called watermark SDK to obtain the corresponding embedded data.

[0045] Specifically, in this embodiment, the watermark SDK in the preset relational database is called through the preset calling interface in the integrated target business system, and the watermark is embedded in the business traffic data to be processed using the corresponding watermark parameters and the called watermark SDK, including: calling the watermark SDK in the preset relational database through the preset calling interface in the integrated target business system; obtaining the watermark parameters configured in advance based on the preset parameter configuration method; wherein the watermark parameters include the corresponding watermark embedding ratio and embedding field; embedding the business traffic data to be processed in units of lines through the watermark SDK and using the watermark parameters to obtain the corresponding embedded data. That is, in this embodiment, the watermark SDK is called through the integrated target business system, and the watermark is embedded using the corresponding watermark parameters. wherein the watermark parameters are parameters configured before the data is produced, and the configuration method can be manually configured or integrated into the business system configuration.

[0046] Furthermore, in combination with the Figure 3 As shown, in this embodiment, regarding the process of embedding watermarks using watermark parameters, the watermark SDK is used to embed watermarks into the service flow data to be processed in units of lines using the watermark parameters to obtain corresponding embedded data, including: the watermark SDK is used to segment the service flow data to be processed using the watermark information in the watermark parameters to obtain corresponding watermark fragments; after partitioning the service flow data to be processed in units of lines, watermarks are embedded into each line of data based on the watermark fragments to complete the watermark embedding operation corresponding to the service flow data to be processed, and the embedded data is obtained. That is, by fragmenting the watermark value (that is, the watermark information), each line of data specifies a field value and the total number of fragments to obtain the remainder, and the obtained remainder can establish a many-to-one relationship between tuple data and fragments, and then the fragment is embedded in another specified field, thereby realizing watermark embedding. In this way, each tuple data is responsible for a watermark fragment alone. In the case where the watermark can be extracted, incrementally adding tuples embedded with watermarks will only increase the robustness of the watermark.

[0047] Step S13: sending the embedded data to a corresponding preset intermediate database or a preset data sharing platform in an incremental manner, and when the amount of the embedded data stored in the preset intermediate database or the preset data sharing platform meets a preset condition, triggering a corresponding watermark extraction operation to obtain the corresponding target business data.

[0048] It should be understood that, in this embodiment, after the watermark is embedded in the unit of line based on the watermark SDK and the watermark parameters, the embedded data is placed in the preset intermediate database or the preset data sharing platform in an incremental manner, and the watermark is extracted when the amount of data in the database is sufficient. That is, when the amount of the embedded data stored in the preset intermediate database or the preset data sharing platform meets the preset conditions, the corresponding watermark extraction operation is triggered, including: judging whether the amount of the embedded data stored in the current preset intermediate database or the preset data sharing platform is less than the preset threshold value, so as to obtain the corresponding judgment result; when the judgment result shows that it is not less than the preset threshold value, the watermark extraction operation corresponding to the embedded data stored in the current preset intermediate database or the preset data sharing platform is completed based on the corresponding watermark parameters. It can be understood that even if the subsequent data is continuously pushed to the preset intermediate database or the preset data sharing platform, that is, in the incremental scenario, it does not affect the normal extraction of the previous and subsequent watermarks.

[0049] In addition, in this embodiment, after the watermark is extracted, the obtained target business data is sent to the data recipient. That is, after the corresponding watermark extraction operation is triggered to obtain the corresponding target business data, it also includes: sending the target business data to the corresponding data recipient based on a preset data transmission interface, so that the data recipient performs the corresponding business processing flow based on the received target business data. In a specific implementation, when the data sender is a provincial government system, the integrated system is the system where the business data sent by the provincial government system is processed, and the corresponding data recipient can be its subordinate municipal government system. The business data generated by the provincial government system is embedded and extracted through the watermark SDK and the integrated business system, and the target business data is securely transmitted to the municipal government system.

[0050] In summary, in this embodiment, 1) the present invention proposes a method for adding watermarks to data at the scheme level. Watermarks can be selectively embedded and extracted for specific data according to specific business scenarios. The provided watermark SDK is lightweight and easy to call, and can be integrated into the business system as needed. 2) Data watermarking is not limited to a specific database level, and watermark embedding and extraction can be more flexible for flowing data in the interface. 3) Data watermark embedding and extraction in incremental scenarios are supported, and real-time data interaction is better supported. 4) Watermark embedding and extraction can be achieved for real-time traffic data, and it does not rely on watermark embedding and extraction in database-to-database migration synchronization scenarios. 5) For more complex watermark embedding scenarios, according to the complexity of the business system, the watermark SDK can be selectively integrated in the corresponding business system or sub-business system to achieve the aforementioned watermark embedding effect.

[0051] It can be seen that in the embodiment of the present application, when the business flow data to be processed sent by the corresponding data sender is received through the preset relational database, the corresponding business system integration operation is triggered; the watermark SDK in the preset relational database is called through the preset call interface in the integrated target business system, and the watermark is embedded in the business flow data to be processed using the corresponding watermark parameters and the called watermark SDK to obtain the corresponding embedded data; the embedded data is sent to the corresponding preset intermediate database or preset data sharing platform in an incremental manner, and when the amount of the embedded data stored in the preset intermediate database or the preset data sharing platform meets the preset conditions, the corresponding watermark extraction operation is triggered to obtain the corresponding target business data. That is to say, when the corresponding business flow data to be processed is received in the present application, the corresponding target business system is integrated based on the corresponding business scenario, and then the watermark SDK in the preset relational database can be called through the target business system and the interface, and the watermark is embedded based on the lightweight watermark SDK, and then the embedded data is pushed to the corresponding database or platform in an incremental manner until the accumulated amount of the embedded data meets the conditions, and the watermark is extracted. In this way, it is possible to effectively implement watermark embedding and extraction of traffic data without relying on watermark embedding and extraction in database-to-database migration synchronization scenarios, and support data watermark embedding and extraction in incremental scenarios, thereby improving the efficiency and flexibility of watermark embedding and extraction and saving human resources.
