Auditing for secure statistical databases
Francis Y. L. Chin, Gültekin Özsoyoğlu · 1981
A statistical database (SDB) is an ordinary database that returns statistical information to user queries. The security problem for the SDB is to control the use of the SDB so that only statistical information is available and no sequence of queries is sufficient to infer protected information about any individual. When such information is obtained, the SDB is said to be compromised.
