identity

Monday, July 28th, 2003

sam.jpegLike many people in the web world I spend some portion of my time puzzling about identity. It seems to me there are a number of issues that are getting lost in the discussion.

For example: we spend a lot of time talking about single-sign-on, but sign-on does not exist in a vacuum. The parties (often quite a few) that adopt various roles in the sign on ritual are entangled in more durable relationships. We have lots of words for this. “Account” for example, but there are lots: marriage, profession, citizenship. The discussions on identity would be well served if people focused more on these relationships.

The discussion would be quite different if we the topic was single-relationship rather than single-sign-on.

In stark terms relationships are about roles. The language is rich in terms for blocking out these pairs: husband/wife, boss/employee, brother/sibling, friend/friend, client/server, buyer/seller. Much of the discussion about identity systems is about intermediating who will be allowed to adopt the rights and privileges of one of these given role. Most of the discussions of identity systems glosses over that both parties must be first class citizens in the discussion. For example that privacy is not just a concern of customers, but also a concern of firms.

The discussion would be quite different if we were discussing firm-privacy rather than customer-privacy.

While many relationships are colored by a dominate/subordinate dialectic modern relationships are significantly more respectful and so to speak peer to peer. The discussion would be quite different if we were focused on that trade-off.

It is traditional to point out that status is associated with the assumption of roles. People figure out who you are by what roles you occupy. All those role names: father, client, seller, sibling, employee are examples. So are all the various professionally certified roles like: Dr, PHD, high school grad, convicted felon. In traditional societies, almost by definition, labels are more highly durable than in modern society where you might be a car salesman one month and a high school teacher the next. American have a story we tell our selves about treating these labels lightly. Economists have a name for this, labor flexibity.

One way to improve our discussions of identity is to draw in the issues of how dynamic and pliable the roles are. That is, of course, deeply connected to issues of how sticky the business models are.

Assuming a role is rarely simple. You don’t get to lead unless others follow; in fact you can’t even follow if you can’t find somebody willing to lead. This creates plenty of ambiguity. One might say: “Yeah, let’s go out to lunch.” as a tentative ambiguous attempt to to capture, at least temporarily, the role of leader. Most relationships and most roles are extremely tentative, implicitly, and pliable. That flexible implicit nature creates freedom for the participants. A flexibility at a very small scale that is directly analogous to the American economy’s flexible labor pool on the large scale.

To me though the important thing about the nature of the flexibility is that the roles are always caught up in a fog of implicit vs explicit facts. If we tentatively allow somebody to adopt the role of leader for a period, and if we leave that implicit then that reduces assorted risks. The risk to him of being embarrassed when we tear down that role, for example. The risk to those who follow him: of the shame of disloyalty when we stop following. An highly implicit role assignment reduces the costs of backing it out when we will discover that he’s not effective. Overall the risk to the enclosing institution when it needs to flexibly re-balance who’s leading what where. Of course leaving implicit is likely to be less efficient than tightening up a clear hierarchy. Leaving things implicit is likely to have higher coordination costs.

Yet again, the discussion of identity systems would be different if it were framed in terms of how can we manage the balance between the implicit and the explicit in our many relationships. Remaining blind to how critical the implicit is in most relationships does huge damage to most discussions about the “identity problem”. Very few identity systems designs put any design effort toward this problem.

Few, if any of these relationships exist in a vacuum. For example my employee/employee relationship is a nest of Russian dolls with one relationship with my boss that has some implicit/explicit stuff going on, that nests inside one with my business, my firm, the legal institutions of various political states, and finally those of the culture. Russian dolls doesn’t begin to do it justice. There are overlapping sets: my profession, industry, local-economy, family traditions, … For example the role of self-employeed, entrepeuer, academic, politian, and many others tends to run in families. Presumably the craft knowledge and social capital get’s passed down.

That these standards or institutions intermediate all relationships and roles makes the whole system significantly richer. The identity standards movement is both focused only on the explicit, but also is naive in failing to grasp that it competes with and threats to displace these existing standards and institutions.

All in all it’s a messy problem and teasing out a solution will take time. It is becoming more common for people in the identity discussion to talk about data as a driver of value. That if we can achieve some standardization (i.e. overcome the social engineering problems outlined above) then we can capture some of the efficencies that letting data move about that is currently hard to get at.

For example I recently refinanced my home. This tedious task requires providing the lender with access to selected data from a dozen different roles I occupy: my citizenship/taxes, my wealth/bank, my income/employeer, etc. etc). In the fantasy world of the future, when the identity problem has been resolved, I will be able to do all that revealing with “the touch of a button”.

Hopefully the preceeding begins to help the reader see why the privacy problem is so subtle. When people talk about privacy they are talking about all the above. Privacy informs the single parties and the single relationship. My bank and I for example our private data. The relationship is not an open-book. I don’t tell my bank that I think their new branch office is lame. They don’t tell me that they think I’m a grade AA customer because my overdraft habits makes me highly profitable. Privacy also means that something about how data is allowed to flow, or leak, from one relationship to another. My bank tells a very selected amount of information to the governments I pay taxes too and to various associated industries (i.e. the credit rating firms).

More interesting, at least to me, is that privacy is also about the implicit/explicit nature of roles. That keeping information implicit is a form of privacy. That even when you make something explicit with a given relationship that keeping it private to that relationship is a key bit of privacy that allows it to be renegotiated over time. That privacy is intimately entangled with the flexiblity to adapt, and that flexiblity and locality helps to temper the loss of efficency that implicit suffers compaired to explicit.

To summarize there are a few aspects of the idenity problem that I think deserve a louder voice in the discussion:

  • relationships
  • roles
  • standards and institutions of various kinds of roles and relationships
  • the value the implicit vs explicit
  • flexiblity vs efficency of relationships
  • the different kinds of privacy
  • overlapping of institutional frames, vs their nesting hierarchy
  • the tension or competition between various institutions and standards

One single relationship? I doubt it.

Nostalgia

Wednesday, July 23rd, 2003


Oh dear, I’ve been wasting time on this thing for more than a year.



Now I can start recycling postings I like on their anniversaries (and maybe I can go fix some of the typos now that I can see them).



A year ago I posted three examples of real world power-law distributions:
World population and electricty, national productivity, internet routers. For desert: computerized astroturf.

Planning is just a way to avoid figuring out what to do next.

A friend at work brought my attention back to a delightful essay Rodney Brooks wrote back in the late 80s.



Talking about how to get your robot to get to the right possition he outlines two approachs. One approach achieves solid top-down control, the other is extremely adaptive and dynamic. He is and was a strong advocate of systems with their design centered in the second approach and ridcules the first approach:


“Manipulator to payload mass ratios of 100 to 1 are almost the rule and ratios of 1000 to 1 are not unheard of. Compare this to the human arm.”


Some institutions are like that.

Reducing Diversity

Wednesday, July 23rd, 2003

Technology erodes the boundries of ecological niches. Local communities are disrupted. This is true in ecologies, cultures, and business. In business you can take sides - you can seek big disruptions, or you can seek ways to defang the disruptions. No matter which side your on Michael Porter’s classic on Competitive Strategy has a facinating list of what prevents an industry from consolidating. What keeps it fragmented. This is one of the very few places I’ve found work that speaks directly to the question of what effects the slope of the power-law.

Here is a quick review of his list. Actually he has four lists: what keeps an industry fragmented, how these might be overcome, why some industries remain stuck in a fragmented state, and finally traps that catch the unwary industrialist into thinking he can consolidate. Really these are all the same list recast into different presentations.

Let me summarize the main list.

What things can keep an industry fragmented?

  • Low Overall Entry Barriers
  • High Exit Barriers
  • Absence of Economies of Scale or Experiance Curve
  • No scale advantage in inputs, i.e. buyers and suppliers
  • High Product differentiation, particularly if based on image.
  • Diverse market needs, and hence diverse product line.
  • Need for close local control and supervision
  • Personal service
  • Heavy creative content
  • High inventory costs and erratic sales
  • Local image or local contact
  • Local regulation
  • Goverment or physical constraint on concentration
  • High transportation costs

For example the first two. That pattern of low entry barrier/high exit makes an interesting combo. When the industry first emerges you get a huge number of firms popping up. Then because it is hard for them to exit (or merge) the industry remains fragmented. I think this happened in the web middleware industry. A huge number of ways of building web sites emerged, lots of sites were built using these assorted systems, reegineering them is extremely expensive; and so now the industry is delightfully diverse. The prescription for addressing this is to try and create some barriers to entry; for example in the middleware example really, really, really complex standard might do the trick.

A Peck a Platforms

Wednesday, July 23rd, 2003


Pretty good little essay on how we are seeing Open Services Platforms emerging in the web and how at some point we should see these
appearing in the financial industry as well.


Organizations shifting to a open service platform model have clear goals. First, they hope to encourage incremental innovation that adds value to their core offering or core service using the resources of others. It’s also a realization that most of the good ideas in the world don’t come from your own staff. While you might very well have lots of smart people in your organization, they are also aware of and sensitive to the inevitable organizational constraints that tend to restrain innovation.

Exactly

I wonder how many of these service platforms we are going to see. Dozens? Thousands?
