I don't know if the results are encrypted or not, but I can't imagine anyone wanting to delibrately hamper the these research results. The reason I thought you were talking about points, is that's the only logical reason anyone would have to tamper with F@H. Competion often brings out the worst in people.
If you would like to find out if the results are encrytped you can check the F@H forums. Normally, I would find the answer and post it here but I'm strapped for time these days. Let us know what you find.
