 SQL guessing advantage analyser has a a user-facing frontend application that allows to extend models by attaching SQL scripts to its elements. SQL queries are added to tasks and SQL database information added to data objects. SQL information is attached by adding specific labels into the XML code of the model. The editor uses SQL guessing advantage analysis tool to perform an analyze on the extended model to combine and present the results. Editor and analysis tool have separate codebases, but they are both required to use the full functionality of the analyser. Communication between the two components is arranged by backend REST service.
+===== Description =====
+We interpret differential privacy in terms of a more standard security measure -- the attacker's guessing advantage. It is defined as the difference between the posterior (after observing the output) and prior (before observing the output) probabilities of attacker guessing the input. The analyser reports the amount of noise that need to be added to achieve a desired upper bound on advantage.
