摘要： Disclosed are a data processing method and apparatus, a computing device, and a storage medium, which belongs to the field of big data technologies. The method includes: determining, based on a query algorithm, a first query output (601) corresponding to an input data set; determining, based on a second query output of an unsampled data record in the input data set and the query algorithm, a perturbation of each of a target quantity of sampled data records in the input data set to the first query output, to obtain sensitivity (602) corresponding to the input data set, where the unsampled data record and the target quantity of data records constitute the input data set; and adding noise to the first query output based on the sensitivity and outputting a noised first query output (603).
