  Secure distributed data compression in the presence of an eavesdropper is
explored. Two correlated sources that need to be reliably transmitted to a
legitimate receiver are available at separate encoders. Noise-free, limited
rate links from the encoders to the legitimate receiver, one of which can also
be perfectly observed by the eavesdropper, are considered. The eavesdropper
also has its own correlated observation. Inner and outer bounds on the
achievable compression-equivocation rate region are given. Several different
scenarios involving the side information at the transmitters as well as
multiple receivers/eavesdroppers are also considered.
