Final answer:
Local Differential Privacy is the level of differential privacy that protects data from even the collectors by randomizing data before collection.
Step-by-step explanation:
The level of differential privacy that secures the outcome from even the people collecting answers is known as Local Differential Privacy (LDP). With LDP, the data is randomized on the user's device before it is sent to the data collector, ensuring that the collector cannot ascertain with certainty the true value of any specific user's data. In contrast, Global Differential Privacy (GDP) applies noise to the data after collection, and while it also protects individual privacy, the collector initially sees the non-noised data.
