  New physics can possibly emerge in the B decays into wrong-sign kaons for
which the standard model contributions are extremely suppressed. We analyze
two-body decays of $\bar{B}^0$ and $B^-$ mesons involving the $b\to dd\bar{s}$
($\Delta S=-1$) and $b\to ss\bar{d}$ ($\Delta S=+2$) transitions in a model
independent way, and examine various wrong-sign kaon signals which are expected
to be observed in the future $B$ experiments. Our analysis shows that it would
be possible to identify the origin of new physics through the combined analysis
of several B decay modes involving one or two wrong-sign $K^*$'s.
