Re: Standing Up Against German Laws - Project HayNeedle



However some of these issues can be mitigated without too much trouble. For example, one could have a dynamically growing dictionary of words to search for based on random words in random results pages that it grabs. At the very least, this would kill any attempts to filter it out of the data mining system.

If the point of the system is primarily to create plausible deniability for the end-user, that is, to allow them to say "hayneedle hit the site, not me, so I am innocent", then I'd say it could be effective in that regard barring some proviso in the law that allow them to persecute someone who did not actually even visit a site of their own volition. Beyond that, it's also effective in terms of turning up the noise to signal ratio and making this law that much less effective, while placing a greater burden of ISPs who are then more likely to lobby against it ever more vigorously.... all while remaining entirely 'white area' in terms of functionality.

I understand your post, but I don't think Mr. Ziegler was over-selling his product's effectiveness beyond what it is really capable of.

Take care, Matt

There's a few things wrong with this approach. Most of them were outlined by Bruce Schneier when he reviewed "TrackMeNot"[1] last year.

The same issues with TrackMeNot apply to Hayneedle, including potential false positives, and list of word combinations that can be filtered out easily, and well, the list goes on.
