Resisting Tracker Attacks By Query Terms Analysis

摘要

Tracker attacks pose a serious threat to databases, especially those used in manufactory and management in industry. These attacks can be used to infer sensitive information in databases and they are difficult to detect. This paper proposes a new approach to dealing with such attacks by analysing each disjunctive term in every query statement. Potential tracker attacks will be detected and then suppressed to avoid any further real attacks. A sample database table and a sample attack are given and analysed to show the effectiveness of the new approach.
