Abstract
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for encoding data on client devices. One of the methods includes obtaining dataset for transmission; dividing the dataset into two subsets according to one or more selection criteria, wherein data items that satisfy the one or more criteria are added to a first subset and the data items that do not satisfy the one or more criteria are added to a second subset, wherein the first subset is smaller than the second subset; encoding the data items of the first subset according to a first encoding technique and encoding the data items of the second subset according to a second encoding technique; applying a local differential privacy (LDP) mechanism to data elements of the first subset and the second subset to generate an LDP message; and transmitting the LDP message to an external recipient.
