Provided you know the time of the transaction, the web server logs will give you details of the IP address all the web transactions are coming from. You can find who owns this IP address via the Ripe (www.ripe.net), Arin (www.arin.net) or Apnic (www.apnic.net) websites. >From this you can find which ISP this address belongs to, and that ISP can verify who was using that IP address at the time. How much assistance you receive from each ISP will vary. That may give you sufficient information to press a case against the person who alleges they didn't access your website, but IANAL. I'm not sure what you mean about information being signed with a given key. Do you mean a personal key like a digital signature, or do you mean the SSL key? - John Airey Internet systems support officer, ITCSD, Royal National Institute of the Blind, Bakewell Road, Peterborough PE2 6XU, Tel.: +44 (0) 1733 375299 Fax: +44 (0) 1733 370848 [EMAIL PROTECTED] The teaching of evolution as a proven fact rather than a theory has done more harm to scientific progress than anything else in history. - NOTICE: The information contained in this email and any attachments is confidential and may be legally privileged.
