Database Authentication by Distortion Free Watermarking
In this paper we introduce a distortion free watermarking technique that strengthen the verification of integrity of the relational databases by using a public zero distortion authentication mechanism based on the Abstract Interpretation framework. The watermarking technique is partition based. The partitioning can be seen as a virtual grouping, which does not change neither the value of the ta...
متن کاملA Generic Distortion Free Watermarking Technique for Relational Databases
In this paper we introduce a distortion free watermarking technique for relational databases based on the Abstract Interpretation framework. The watermarking technique is partition based. The partitioning can be seen as a virtual grouping, which does not change neither the value of the table’s elements nor their physical positions. Instead of inserting the watermark directly to the database par...

متن کاملDatabase Integrity Checking
Integrity constraints (or simply “constraints”) are formal representations of invariant conditions for the semantic correctness of database records. Constraints can be expressed in declarative languages such as datalog, predicate logic, or SQL. This article highlights the historical background of integrity constraints and the essential features of their simplified incremental evaluation. It con...
متن کاملReversible Watermarking for Relational Database Authentication
A reversible watermarking scheme for relational databases is proposed in this paper to achieve lossless and exact authentication of relational databases via expansion on data error histogram. This reversible watermarking scheme possesses the ability of perfect restoration of the original attribute data from the untampered watermarked relational databases, thus guaranteeing a “clear and exact” t...
