Issuers of indirect (I like this term better than unverifiable) transactions are not collecting data about individuals. We do not have any method other than direct registration on our site or another site sharing the information, to understand "who" a viewer is. We set cookies in user-agents. We do not know the individual! Part of the fear of privacy violation is that we can track someone down, get their phone number, etc. and this is not true. So, we collect data about the behavior of people who use and potentially share a web browser, but we do NOT know who that person is. In no cases have we ever found a web site who is willing to share information about registered users. One of the big issues is what do the sites who issue verifiable transaction cookies do with their information. If they were to provide us with their registered users' data and the IDs of the issued cookies, we could completely skirt the issue of unverifiable transactions (with some work). So, there are ways around this. > without their knowledge or consent, and once collected, the user > has no idea what it's going to be used for, or by whom it will be used. > The proposal provides a mechanism of informing users of business and > data relationships other than just the ones dictated by a particular domain, > and a mechanism that allows them to weigh the benefits and hazards of > accepting cookies from entities. > <text deleted> > Conversely, tripleclick may actually collect names and phone numbers How...tripleclick does not have access to names and phonenumbers unless someone gives it to them.

I honestly believe that once again the big issue is for people to understand exactly what are the potential breaches of privacy and how they can occur. Let's face it, the Ad networks are interested in tracking user behavior, no secret there....however, there are limits to what we can and would do with this information. It is our policy to completely disclose how we use cookie data (and this will show up on our web site in the near future). I also believe that other Ad networks disclose this information. I personally would accept the certification process if this is the only alternative. One issue with this is how fast can sites be certified, what are the criteria, and how much will it cost? I would prefer an easier solution which I assume has been discussed (please excuse my late entrance into this mailing list and my potential ignorance of history) which is to make the default for user-agents to accept all cookies with the ability to turn off unverifiable transactions if desired. Can anyone from the companies providing browsers give a company position on what they intend to do with respect to RFC 2109 and the default of turning off unverifiable transactions. > > Jonathan > > =============================================================== > Jonathan Stark (415) 858 1930 x217 > eTRUST Technical Director stark@eTRUST.org -- Steve Reiss FlyCast Communications email sreiss@flycast.com 123 Townsend St. Phone 415-975-5373 Suite 226 Fax 415-977-1009 San Francisco, CA 94107
