摘要
An amount of noise to add to a query output may be selected to preserve privacy of inputs while maximizing utility of the released output. Noise values can be distributed according to a substantially symmetric exponential density function (“exponential distribution”). That is, the most likely noise value can be zero, and noise values of increasing absolute value can decrease in probability according to the exponential function.
