Intro Statistical Database Security Ppt This document introduces statistical database security. it discusses how statistical databases contain confidential individual data that must be protected. it provides an example of a person database with attributes like name, income, address. statistical queries apply functions like count, sum, average to populations defined by conditions. Statistical database security in a statistical database, there are queries that do not permit access to individual entries, but rather to statistical functions involving many entries, such as averages, 3.

Introduction to database security 2. improper access by unauthorized users, protection from inference (usually statistical databases). user types for dbms control the access to statistical databases. Data swapping values are exchanged within a column, in such a way that any statistical computation over the column does not change. a t order statistic is one which is computed using t attributes in the relation. data swapping for t columns such that any t order statistic remains unchanged, and higher order ones are not necessarily correct, is. Relational databases store data in tables with rows and columns and use queries to access data. database management systems provide access controls but inference is still a risk. statistical databases allow statistical queries while preventing inference but this remains challenging. An inference channel is a channel where users can find an item x and then use x to derive y as y=f(x). statistical inference is a further aspect involving of deduction of statistical data via statistical functions.
