摘要
A method classifies data to determine hidden states of a machine by first acquiring data from the machine in a client, which is permuting randomly, and then chaff is inserted before transmitting to server as private data. The server classifies the private data according to a hidden Markov model to obtain permuted noisy estimates of states of the machine and the chaff, which are transmitted to a third party. The third party removes the chaff and inverts noisy estimates using a permutation ordering to obtain unpermuted noisy estimates of the states of the machine.
