Homomorphic techniques can be applied to trace data to anonymise, but 
preserve the structure required for the experiment. Of course this often 
needs to be hand-crafted to preserve the particular structure required, so 
could be more difficult than the original experiment (or impossible). But 
the excellent paper below shows (and proves) it can be done for prefix 
structure at least...
