Portable identity as vaselineSubmitted by brad on Thu, 2008-03-13 17:47
Earlier I wrote an essay on the paradox of identity management describing some counter-intuitive perils that arise from modern efforts at federated identity. Now it's time to expand these ideas to efforts for portable personal data, especially portable social networks.
Partly as a reaction to Facebook's popular applications platform, other social networking players are seeking a way to work together to stop Facebook from taking the entire pie. The Google-lead open social effort is the leading contender, but there are a variety of related technologies, including OpenID, hcard and other microformats. The primary goal is to make it easy, as users move from one system to another, or run sub-abblications on one platform, to make it easy to provide all sorts of data, including the map of their social network, to the other systems.
Some are also working on a better version of this goal, which is to allow platforms to interoperate. As I wrote a year ago interoperation seems the right long term goal, but a giant privacy challenge emerges. We may not get very many chances to get this right. We may only get one.
The paradox I identified goes against how most developers think. When it comes to greasing the skids of data flow, "features" such as portability, ease of use and user control, may not be entirely positive, and may in fact be on the whole negative. The easier it is for data to flow around, the more it will flow around, and the more that sites will ask, and then demand that it flow. There is a big difference between portability between applications -- such as OpenOffice and MS Word reading and writing the same files -- and portability between sites. Many are very worried about the risks of our handing so much personal data to single 3rd party sites like Facebook. And then Facebook made it super easy -- in fact mandatory with the "install" of any application -- to hand over all that data to hundreds of thousands of independent application developers. Now work is underway to make it super easy to hand over this data to every site that dares to ask or demand it.
