Wikipedia talk:IP Hash

From Wikipedia, the free encyclopedia

[edit] did anything ever come of this?

I think it would go a long way to ending the sock puppet problem. – Þ  08:57, 7 March 2007 (UTC)

[edit] Security viewpoint & problems with interpretation

• Don't think about it as about hash - like sha256(ip). IP space is small, it's trivial to build a dictionary.
• If it would be something like sha256(ip + secret_key), privacy of all ips depends on secrecy of that secret_key, forever. There is now way how the system would be able to recover from successful attack.
• IP data are often misleading without further investigation and good understanding of internet technology. Its trivial to foil such test, false positives are certain

I'm completely against. --Wikimol 20:07, 1 April 2007 (UTC)
