背景技术Background technique
信息技术发展迅猛，以大数据分析、新一代人工智能技术为代表，已 在国家治理、机构精益化管理、提升客户服务等方面发挥了重要作用。数 据的充分融合和共享已成为大势所趋，必将为经济社会发展带来深远影响。 数据已成为国家和组织机构的重要资产。然而，数据安全问题却日益突出， 数据的盗用和滥用问题日趋严重，是目前妨碍数据进一步进行融合共享的 首要问题。The rapid development of information technology, represented by big data analysis and new-generation artificial intelligence technology, has played an important role in national governance, lean management of institutions, and improvement of customer service. The full integration and sharing of data has become an irresistible trend and will definitely have a profound impact on economic and social development. Data has become an important asset for countries and organizations. However, the problem of data security is becoming more and more prominent, and the problem of data theft and abuse is becoming more and more serious, which is the primary problem currently hindering the further integration and sharing of data.
数字水印(Digital Watermarking)技术是将一些标识信息(即数字水印) 直接嵌入数字载体当中(包括多媒体、文档、软件等)，且不影响原载体的 使用价值，也不容易被探知和再次修改，但可以被生产方识别和辨认。数 字水印是实现数据防伪追责、版权保护的有效办法。结构化数据具有价值 密度高、易于分析等特点，但由于结构化数据本身的特点，其可供嵌入水 印的空间很少，因而数字水印技术在结构化数据中应用较少，且目前缺少对于结构化数据的泄露追责方法。Digital watermarking (Digital Watermarking) technology is to embed some identification information (that is, digital watermark) directly into digital carriers (including multimedia, documents, software, etc.), without affecting the use value of the original carrier, and it is not easy to be detected and modified again. But it can be identified and identified by the producer. Digital watermarking is an effective way to realize data anti-counterfeiting accountability and copyright protection. Structured data has the characteristics of high value density and easy analysis, but due to the characteristics of structured data itself, there is very little space for embedding watermarks, so digital watermarking technology is rarely used in structured data, and there is currently a lack of structural data. Accountability methods for data breaches.

本发明实施例提供了一种结构化数据数水印的标注方法，该方法可以 应用于对各电力公司待分发的结构化数据集嵌入数字水印，如图1所示， 该方法包括以下步骤：The embodiment of the present invention provides a method for marking structured data digital watermarks, which can be applied to embed digital watermarks in structured data sets to be distributed by various electric power companies, as shown in Figure 1, the method includes the following steps:
步骤S101：获取待发送的结构化数据集及结构化数据集的传输属性信 息，在实际应用中，该待分发的结构化数据集为某电力公司的客户用电数 据，该结构化数据内容如表1所示：Step S101: Obtain the structured data set to be sent and the transmission attribute information of the structured data set. In practical applications, the structured data set to be distributed is the customer electricity consumption data of a power company. The structured data content is as follows: Table 1 shows:
表1Table 1
该结构化数据集的传输属性信息可以包括：结构化数据集的分发日期 和接收者的用户信息，本实施例只是举例说明，并不限定传输属性信息的 种类。The transmission attribute information of the structured data set may include: the distribution date of the structured data set and the user information of the recipient. This embodiment is only an example and does not limit the type of transmission attribute information.
步骤S102：提取结构化数据集中预设范围内的原始数据，识别原始数 据的数据类型；在具体应用中，对与上述步骤S101中结构化数据集，预设 范围设置为POWER1、POWER2、POWER3、POWER4、POWER5、POWER6、 POWER7和MOBI_NO，该预设范围内的原始数据如表2灰色部分所示：Step S102: extract the original data within the preset range in the structured data set, and identify the data type of the original data; in specific applications, for the structured data set in the above step S101, the preset range is set to POWER1, POWER2, POWER3, POWER4, POWER5, POWER6, POWER7 and MOBI_NO, the original data within the preset range is shown in the gray part of Table 2:
表2Table 2
识别结构化数据集中的POWER1、POWER2、POWER3、POWER4、 POWER5、POWER6、POWER7和MOBI_NO范围内的原始数据类型，， MOBI_NO(即用户的手机号)为字符型数据，POWER1、POWER2、 POWER3、POWER4、POWER5、POWER6、POWER7为数值型数据；Identify the original data types in the range of POWER1, POWER2, POWER3, POWER4, POWER5, POWER6, POWER7 and MOBI_NO in the structured data set, MOBI_NO (that is, the user's mobile phone number) is character data, POWER1, POWER2, POWER3, POWER4, POWER5, POWER6, POWER7 are numerical data;
步骤S103：根据传输属性信息生成标识数据，例如，将上述步骤S101 中的结构化数据集的分发日期和接收者的用户信息生成标识数据，该标识 数据后续可用于寻找结构化数据集的负责人。。Step S103: Generate identification data according to the transmission attribute information, for example, generate identification data from the distribution date of the structured data set in the above step S101 and the user information of the recipient, and the identification data can be used to find the person in charge of the structured data set later . .
步骤S104：根据预设的水印算法及所述原始数据的数据类型、标识数 据对原始数据进行转换，得到嵌入标识数据的结构化数据集；将数字水印 嵌入数据中有很多种算法，例如，空域算法、Patchwork算法、变换域算法、 压缩域算法、NEC算法和生理模型算法等，可以根据不同的原始数据的数 据类型和标识数据采用不同水印算法，将标识数据嵌入结构化数据集中， 例如，对于本实施例中原始数据的数据类型，由于字符型数据(MOBI_NO) 是手机号以及数值型数据(POWER1、POWER2、POWER3、POWER4、 POWER5、POWER6、POWER7)是小数，所以采用手机号前缀水印算法 和时空域LSB(±1)算法作为水印算法。Step S104: Convert the original data according to the preset watermark algorithm, the data type of the original data, and the identification data to obtain a structured data set embedded with identification data; there are many algorithms for embedding digital watermarks into data, for example, airspace Algorithm, Patchwork algorithm, transform domain algorithm, compressed domain algorithm, NEC algorithm and physiological model algorithm, etc., can adopt different watermarking algorithms according to different data types of original data and identification data, and embed identification data into structured data sets, for example, for The data type of the original data in this embodiment, because the character data (MOBI_NO) is the mobile phone number and the numerical data (POWER1, POWER2, POWER3, POWER4, POWER5, POWER6, POWER7) is a decimal, so adopt the mobile phone number prefix watermark algorithm and The time-space domain LSB(±1) algorithm is used as the watermarking algorithm.
通过实施本发明实施例中的一种结构化数据水印的标注方法，将结构 化数据集的传输属性信息作为标识数据嵌入结构化数据集中，后续根据泄 露的结构化数据集提取标识数据，就能根据传输属性信息找到泄露结构化 数据的负责人。By implementing a structured data watermarking method in the embodiment of the present invention, the transmission attribute information of the structured data set is embedded in the structured data set as identification data, and the identification data is subsequently extracted according to the leaked structured data set.

Step S103 in the above embodiment generates identification data according to the transmission attribute information through the following process: extracting the receiving The ID of the party and the digital information in the transmission date information, sort the digital information according to the preset sorting method, and generate the identification data; for example, the recipient ID of the structured data set is 4231, and the transmission date is 2018 On June 21, the arrangement is such that the receiver's ID is first and the transmission date is last, so the extracted digital information is 4231180621.

表3table 3
表4Table 4
根据表4所示的结构化标识数据选择上述实施例中所述的手机号前缀 水印算法和时空域LSB(±1)算法，该手机号前缀水印算法为当嵌入比特 为0时，手机号不做变动；当嵌入比特为1时，手机号前增加前缀“+86”， 时空域LSB(±1)算法是对数值型数据进行加1减1操作，为极大减少对 原始数据的影响，所以对数据中的万分位进行加1减1操作，其具体算法 如表5所示：According to the structured identification data shown in Table 4, the mobile phone number prefix watermark algorithm and the space-time domain LSB (±1) algorithm described in the above-mentioned embodiments are selected. The mobile phone number prefix watermark algorithm is that when the embedded bit is 0, the mobile phone number does not Make changes; when the embedded bit is 1, the prefix "+86" is added before the mobile phone number. The time-space domain LSB (±1) algorithm is to add 1 and subtract 1 to the numerical data. In order to greatly reduce the impact on the original data, Therefore, the operation of adding 1 and subtracting 1 to the ten-thousandth place in the data is performed, and the specific algorithm is shown in Table 5:
表5table 5
