One way to prevent reverse engineering is to “blur” the data points by using noise addition through differential privacy. The goal is to ensure that the aggregated data is still useful, while also making it nonspecific enough to avoid revealing the underlying identifiers. This is done by using an algorithm to generate values that remain meaningful and yet are nonspecific.
