To get more intuition into this let us return to the example of the medical database and a query Q(i),! (which can also be seen as the function f ,! ) to find how many people in the first i,! rows of the database have diabetes. Clearly, if we change one of the entries in the database then the output of the query Q(i),! will change by at most one. So, the sensitivity of this query is one. It so happens that there are techniques (which are described below) using which we can create a differentially private algorithm for functions with low sensitivity.
