I recently had the delightful opportunity to keynote at the NordicAPI conference. It's a great little conference, with fascinating conversations and people proving that the Valley isn't the only locus of change in the software industry.
I was exploring the topic of what identity means in the context of an API and Big Data driven world. The basic conclusion that I reached is that the de-silofication of the enterprise will lead to a revolution in identity.
Identity will no longer be tied to a location or business unit, but by a set of flexible, distributed rules. In addition, as Big Data systems come online, there will be a shift from "show all data by default" to "flexible granularity," where access can be controlled from individual datums to massive correlated data sets.
