Discrete Laplace Mechanism

Definition

The Discrete Laplace Mechanism is a privacy-preserving technique used in differential privacy to add calibrated random noise to query results, typically counts or sums of integer values. This addition of noise ensures that individual data points cannot be precisely inferred from the aggregate output, even with repeated queries. The mechanism guarantees a specific level of privacy by sampling noise from a discrete Laplace distribution. It is particularly suitable for data where exact counts are critical but individual privacy must be protected.
