Distributed Hypothesis Testing Under Privacy Constraints Academic Article uri icon


  • A distributed binary hypothesis testing problem involving two parties, a remote observer and a detector, is studied. The remote observer has access to a discrete memoryless source, and communicates its observations to the detector via a rate-limited noiseless channel. Having access to another discrete memoryless source, the detector performs hypothesis test on the joint distribution of its own observations with that of the observer. While the goal is to maximize the type 2 error exponent of the test for a given type 1 error probability constraint, it is also desired to keep a private part, which is correlated with the observer's observations, as oblivious to the detector as possible. Considering equivocation and average distortion as the metrics of privacy at the detector, the trade-off between the communication rate of the channel, the type 2 error exponent and privacy is studied. For the general hypothesis testing pro...
