    摘要: A system and method is provided for identifying the source of an unauthorized database disclosure. The system and method stores a plurality of past database queries and determines the relevance of the results of the past database queries (query results) to a sensitive table containing the unauthorized disclosed data. The system and method also ranks the past database queries based on the determined relevance. A list of the most relevant past database queries can then be generated which are ranked according to the relevance, such that the highest ranked queries on the list are most similar to said disclosed data. Three techniques used in embodiments of the invention include partial tuple matching, statistical linkage and deviation probability gain.
