摘　　要：国家大数据战略下,数据需要各个环节间流转、重组、使用,同时数据的管理控制权也随之转移,数据一旦泄露,数据提供者非常希望能够精确溯源是否是数据使用环节的责任。数据水印技术通过高仿真实数据内容,并参入标识信息,数据使用者不易察觉,并且有很强的隐蔽性和抗毁性,可有效满足数据安全流转需求。文章提出了一种基于自适应嵌入的高抗毁数据水印方法,可灵活针对目标数据的特性,在保证目标数据可用性的前提下,尽可能的保证数据水印嵌入率,提高数据水印的抗毁性。Under the National big data strategy, data needs to be transferred, reorganized and used among every chain. At the same time, the management control of data is also transferred. Once the data is leaked, the data provider hopes to be able to accurately trace whether it is the responsibility of the data use link. Data watermarking technology can effectively meet the needs of data security circulation by highly imitating the real data content and adding identification information, which is not easy to be detected by data users, and so data watermarking technology has strong concealment and invulnerability. This paper proposes a high invulnerability data watermarking method based on adaptive embedding, which can flexibly face to the characteristics of the target data, and then ensure the embedding rate of the data watermark as much as possible and the availability of the target data, and also improve the invulnerability of the data watermark.
