Understood completely and I know how SSL, checksums, asymmetric keys, etc work but without the understanding that content drifting away from its original sources corrupts means the buyer doesn't understand the technical solution is not the whole solution.
In effect, regardless of the wrapper, unless you have the original 1959 first episode of Rocky and Bullwinkle, you probably can't answer those trivia question correctly. If you don't have the authentication and authorization, you don't have access to the original source. If you don't have the digital signature and checksum technology, I can't trust your answers without the original sources. This is the real problem of named data sharing. Otherwise, URIs with registries make the name sharing easy, and the rest is authentication, authorization, signatures, etc. I don't think the problem of discoverability is as big as the speaker believes it is. It isn't just trust. It's verification. For that, you must have an authentic copy of the original source or access which amounts to the same thing but if access, you have to prove that. Names alone won't make that happen. len From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Peter Amstutz Well, on a technical level you have digital signatures that give you a technical way to verify that information from a given source has not been tampered with. Provided you trust that the public key used to sign that data did in fact come from that entity, of course, but trust has to start somewhere. On a social level, you're right, people tend to introduce errors (either accidentally or deliberately) in information. There isn't a technical solution to that. But that's not the kind of transmission we're dealing with; we're only concerned with exact digital copies. Whether the source itself is an eyewitness account, a newpaper article or a wikipedia writeup, the goal is simply propagation of the actual digital document without allowing for the introduction of errors into the document itself. _______________________________________________ vos-d mailing list vos-d@interreality.org http://www.interreality.org/cgi-bin/mailman/listinfo/vos-d
