Hi - I'm coming into this discussion late, and though I've tried to catch up, please forgive me if you think I've missed something in earlier stages of the debate. However, as a philosopher concerned with online ethics (as well as a web analyst), I'm disturbed by the tone of this discussion, so I'm throwing in my point: The idea that a person can be treated like a computing resource is questionable. It sounds like instrumentalism - treating people as things, which is the starting point of most human evil. The principle that an identifier in one system is portable to others refers to computing resources, not human beings. There are no principles in web computing which were ever intended to apply to people. This is why initiatives like WebID exist at all - they are trying to compensate for the fact the internet has nothing within it pertaining to humans. The concept of a "reputation footprint" is also highly debatable. Personally, I find the idea that I would have a single online profile, uniting all my web activities, and traceable back to the real human me, as horrifically totalitarian, and a step backward. I don't have such a limitation in the real world. I can be anonymous when I walk the city, enter shops, and pay by cash. I can conceal my religious or political beliefs from my workmates, so as to avoid being judged by them on irrelevant criteria, or simply because I want to live privately. I can decide my life has been a mess, then move to a new city, where no one knows me, and start afresh, my previous history forgotten. We must have the same level of forgetfulness on the web, the same ability to split our activities and present only partial views of ourselves to different groups. These are fundamental aspects of human existence which have remained for thousands of years. They enable us to work and socialise with others who we otherwise would be in conflict with. Organisations are different. They are not people. Any initiative which treats organisations, documents and human beings as the same is denying the essential dignity of the individual, and their right to chose how openly or privately they wish to live. I can understand why I might want a system which enables me to lock my identity to a resource, but that should be a voluntary system, and it should enable me to have multiple WebID's (or equivalent), and it should permit me to keep my personal identity totally anonymous. WebId is a particularly dangerous concept. It totally depends on the unbreakability of the private key. Does anyone in this group seriously believe there's such a thing as unbreakable encryption, or a flawless computing system? If people trust WebID's, what chance do you think anyone will have of convincing the world their WebID has been faked or hijacked, or their certificate stolen, etc? If WebID was used for government, financial or employment purposes, what harm could fall on someone under such circumstances? The same is true of any computing system which seeks to lock an IT resource to a real person. The connection between the two will always be problematic and untrustworthy. In terms of online privacy, we cannot possibly imagine what use nasty people will make of personal data 10, 20, or 50 years from now. We simply cannot know what technology or business models people will invent. All we can be sure of is that stuff we can't imagine now will dominate the web of the future. This means we can't argue in terms of trying to achieve specific effects, because we can't know what the full range of effects will be. The only solution is to focus on avoiding the potential for harm. This means we must take a fantastically conservative attitude to online privacy, and resist every attempt to reduce it. In this light, one has to ask - where are the anonymity initiatives? Where's my IP-rotation plug-in, my user agent obfuscation add-on, etc? The web is a fairly good thing as it is. Before we seek to "improve" it, we need to be absolutely certain we are addressing a genuine problem and that the solution won't harm more than it helps. In the larger context, this means "Web-scale verifiable identity" should be no more than a minor item of optional technology used by a few people for specific purposes. It should be enacted in a manner which is aware nasty people and governments could force it on people as a means of exploitation and control, which means making it hard to manage centrally and avoiding uniform standards. The emphasis should always be on the avoidance of possible harm, even if this means not getting the best technology.

The web is predicated on the principle that an identifier in one system (eg a browser) will be portable to any other system (eg a search engine) and vice versa. The same principle applied to identity would allow things to scale globally. This has, for example, the benefit of allowing users to take their data, or reputation footprint when them across the web. I think there is a focus on WebID because it is the only identity system to date (although yadis/openid 1.0 came close) that easily allows this. I think many would be happy to use another system if it was global like WebID, rather than another limited context silo. > I think there is a lot of confusion about the difference between identifier and identity.

An data object identifier can resolve to said data objects representation. A Web accessible profile document is an example of a data object. On the Web a profile document can be denoted by an HTTP URI/URL. In addition, the subject (which can be *anything*) of a profile document can also be denoted by an HTTP URI. Basically, this is what the Linked Data meme [1] by TimBL is all about. Note, WebID is fundamentally an application of Linked Data principles specifically aimed at solving the problem of Web-scale verifiable identity for people, organizations, software, and other conceivable entities. > > $ Identity: Any subset of an individual's attributes that > identifies the individual within a given context.

There, very few standards exist (this is the step that follows OAuth). The reason for the lack of standards is not that it isn't possible to standardize these protocols but there are just too many applications. A social network is different from a system that uploads data from a smart meter. Facebook, for example, uses their social graph and other services use their own proprietary "APIs" as well. > > This is the identity issue. > > You are mixing all these topics together. This makes it quite difficult to figure out what currently deployed systems do not provide. Henry isn't mixing up the issues. What might be somewhat unclear to you is the critical role played by Linked Data, and the fact that a WebID is just a cryptographically verifiable denotation mechanism (an identifier) for people, organizations, software agents, and other real world entities that aren't Web realm data objects (or documents). Linked Data introduces a power nuance that enables you leverage *indirection* via the use of HTTP URIs to unambiguously denote a Web realm data object (e.g., a profile document) and a real world entity (that's the subject of the profile document) described by said data object. Net effect, either denotation resolves to the same document content (actual data or Web resource). The documents in this context are comprised of RDF data model based structured content i.e., an entity-attribute-value or subject-predicate-object graph. Also note that WebID and OpenID bridges already exist in the wild that work, and these serve as powerful demonstrations of the value that WebID brings to bear.
