摘要： A system and method that provide resilient watermarking of digital data, including numeric and categorical relational data. The method and system are premised upon a framework considering the higher level semantics to be preserved in the original data. The system and method also provides a technique for enabling user-level run-time control over the properties that are to be preserved, as well as the degree of change introduced. The system and method are resilient to various important classes of attacks, including subset selection, addition, alteration, or resorting, horizontal or vertical data partitioning, and attribute remapping. For numeric relational data, approximately 40-45% of the embedded watermark may survive approximately 45-50% of original data loss, while for categorical relational data, the watermark may survive approximately 80% of original data loss with only approximately 25% degradation of the watermark.
摘要翻译：提供数字数据的弹性水印的系统和方法，包括数字和分类关系数据。该方法和系统以考虑在原始数据中保留的较高级别语义的框架为前提。该系统和方法还提供了一种技术，用于对要保留的属性以及引入的变化程度进行用户级运行时控制。该系统和方法适用于各种重要的攻击类别，包括子集选择，添加，更改或撤销，水平或垂直数据分区和属性重映射。对于数字关系数据，大约40-45％的嵌入水印可以承受原始数据丢失的大约45-50％，而对于分类关系数据，水印可以承受原始数据丢失的大约80％，只有大约25％的降级水印。

摘要： A system and methods for providing guarantees about faithful execution of databases that run under the control of an untrusted entity—such as a cloud computing service provider—that is different than the owner of the data and applications being outsourced; or runs on a server that may be compromised by unauthorized users. Specifically, the system and methods establishes that an untrusted database is being faithfully hosted and provides indemnity for the service provider from false claims, enabling the server to prove its innocence against untrue claims of faulty operation. The invention also provides assured provenance for all changes made to the database.
摘要翻译：一种系统和方法，用于提供关于在不受信任实体（如云计算服务提供商）控制下运行的数据库的忠实执行的保证，该数据库与外包的数据和应用程序的所有者不同; 或者在可能被未经授权的用户受到威胁的服务器上运行。具体来说，系统和方法确定了不信任的数据库被真实地托管，并为服务提供商提供虚假的索赔提供赔偿，使得服务器能够证明其对于错误操作的不真实的声明的无辜。本发明还为数据库所做的所有更改提供了有保证的来源。
