Not surprisingly, differentiator 2 can just be the first byte (or machine word). Differentiator 3 can be the last byte (or word). At that point, 99.99% (in practice more 9s) of files are different and you’re read at most 2 blocks per file. I haven’t figured out a good differentiator 3 prior to hashing, but it’s already so rare, that it’s not worth it, in my experience. |
