Systems and methods for injecting noise into secure function evaluation to protect the privacy of the participants and for computing a collective noisy result by combining results and noise generated based on input from the participants. When implemented using distributed computing devices, each device may have access to a subset of data. A query may be distributed to the devices, and each device applies the query to its own subset of data to obtain a subset result. Each device then divides its subset result into one or more shares, and the shares are combined to form a collective result. The devices may also generate random bits. The random bits may be combined and used to generate noise. The collective result can be combined with the noise to obtain a collective noisy result.
