Constraints Inference Channels and Secure Databases
[chapter]
2000
Lecture Notes in Computer Science
Preserved Fulltext
Database constraints over both extensional and intensional databases form an (n + k)-dimensional constraint object. ...
The database is represented as a point i n a n ( n+k)-dimensional constraint space, where n is the numberofnumerical data items stored in the database (extensional database) and k is the numberofderivable ...
It is our view, however, that the main technical di culty of solving the inference channel problem lies in developing inference algorithms that guarantee data con dentiality. ...

AbstractÐThis paper investigates the problem of inference channels that occur when database constraints are combined with nonsensitive data to obtain sensitive information. ...
The Disclosure Inference Engine generates all the information that can be disclosed to a user based on the user's past and present queries and the database and metadata constraints. ...
Techniques to detect and remove inference channels can be organized into two categories: The first category includes techniques that detect inference channels during database design; any channels are removed ...

The problem of enforcing confidentiality in the presence of integrity constraints in secure and, in particular, in multi level databases is still open. ...
In this work we argue that there can never be a trade-off between these two properties for integrity is a fundamental quality of every database, ie also a secure one. ...
There is a static inference channel if data at a low security level does not satisfy the integrity constraints, and there is a dynamic channel if data with a high security level force an update operation ...

A semantic inference model (SIM) is constructed based on the data dependency, database schema and semantic relationship among data. ...
However, malicious users can exploit the correlation among the data and infer sensitive information from a series of seemingly innocuous data access. ...
Furthermore, to provide scalable inference in large systems, feasible inference channels that are based on query and database schema are generated to guide the data inference [CCH94] . ...
