摘要：

Security is considered m the context of an abstract model of a database where queries revolving the mean or medmn of a pnvdeged field are allowed For this model, the method oflumtmg the number and types of quenes that can be asked of such a database is constdered as a means for providmg statistical access whale insuring that no mdlwdual data are compromisedThe resultant questions are primarily combinatorial m nature and are mterestmg m themselves. © 1979, ACM.
