Technical Problem

[0003]目前，已有研究中采用文档水印、页面水印等传统的标识方法对外发数据属性进行标识，该方法可以显性的标识数据来源、数据接收等信息，如果文档水印、页面水印随着数据发生泄露，这种方法可以实现对数据泄露者的追责，但是无法追溯到数据管理者在数据外发处理过程中的工作失误，从而无法对造成数据泄露的管理者进行追责；同时，采用文档水印、页面水印作为数据标识还存在以下问题：1.传统的文档水印、页面水印是对数据载体添加标识信息，数据在正常的流转使用过程中数据形式可能发生变化，此时通过传统的文档水印、页面水印来标识数据的流转信息就会有局限，甚至造成数据标识丢失；2.传统的文档水印、页面水印是展现在所有用户面前的，用户特意的祛除文档水印、页面水印的技术也相对成熟，数据标识很容易被识别、篡改和删除；3.数据安全处理措施也不能够显性展示，否则数据攻击者能够有条件进行针对性采取破坏措施

Benefits of technology

[0056]本发明提供了一种外发数据生成方法、外发安全管控方法及系统，包括：获取待发数据、待发数据的属性信息以及待发数据在各生成环节的操作数据；基于所述待发数据的属性信息生成外发任务指纹，并建立所述外发任务指纹与所述待发数据在各生成环节的操作数据的关联关系；将所述外发任务指纹映射成与待发数据类型一致的密钥，并基于预设的数据水印添加策略将所述密钥添加到所述待发数据中，形成含有数据水印的待发数据；当含有数据水印的待发数据发送后并出现泄露时：基于泄露数据中提取出的数据水印，可反向追溯数据接收者以及数据在各生成环节操作数据，进而实现对数据泄露的追责，本发明中待发数据的数据水印不仅可标识数据的属性信息，还可关联数据在各生成环节的操作数据，一旦发生敏感数据泄露，无论是数据管理者在数据生成环节操作不当，还是接收者没有尽到数据安全防护责任，都可以进行精准追责。

Abstract

The application provides a kind of data generation method, data sending security control method and system, comprising: generating data sending task fingerprint based on the attribute information of data to be sent, establishing the association between data sending task fingerprint and the operation data of each generation link of data to be sent;The key is mapped into the data to be sent by mapping the key into the data to be sent based on the preset data watermark adding strategy, and the data to be sent containing data watermark is formed;When the data containing data watermark is leaked: based on the data watermark extracted in the leaked data, the data receiver and the operation data of the data in each generation link can be traced back reversely, the accountability of data leakage is realized, the data watermark of the data to be sent in the application can not only identify the attribute information of data, but also associate the operation data of data in each generation link, once sensitive data leakage occurs, whether the data manager operates improperly in the data generation link or the receiver does not fulfill the data security protection responsibility, accurate accountability can be carried out.
