There’s no such thing as “similar enough” with a hash. One bit change in the source imagine creates as large a Hamming distance as possible in the hash bits - that’s literally the point. Unless I’m missing something that seems ludicrous to consider a hash as close enough to be a reason for probably cause.

- sigilis 3y agoIn this case, a false positive might be a good thing from their perspective. If they can show that you have a close match it means they have an excuse to investigate you more thoroughly should they desire even if the real reason is that they suspect you of something else.
- demondemidi 3y agoThat's fascinating. Thanks. I've only encountered cryptographic hashes, or hashes for data structures that are limited by address size.
