The proliferation of online services has created a huge problem of identity management. Every week there’s a new demand to create an account or profile, which means each of us has an ever-growing archipelago of disconnected personas. OpenID is an attempt to solve the problem by having one set of credentials that can is used by a growing number of sites.

 

Simon Willison’s screencast on How to use OpenID is very much worth the time. He explains the benefits and addresses the potential problems. Tom Coates is on about social whitelisting with OpenID, which takes the combines the advantages of social software with trusted identities. The idea sounds like a deceptively simple solution to the problem of comment spam that only seems to loom larger every day

Identity management trends pinpointed by Burton report:

The control of users’ access rights is the most important consideration when rolling out identity management solutions, according to analyst Burton Group.

Burton analyst Mike Neuenschwander said the issue was familiar to enterprises, but regulatory drivers,such as Sarbanes-Oxley, have  brought identity control optimisation technologies even more to the forefront.

“Defining and maintaining access rights continues to be a big pain point for  enterprises,” said Neuenschwander. “Some products approach entitlement management from the audit perspective, and some focus on defining and managing business and IT roles; it can be tricky and extremely expensive,” said Neuenschwander.

Burton Group said the majority of market activity will be focused on technologies specialising in data-mining tools for role definition.

Startups and specialist suppliers are more active in this space than major brands, which could lead to acquisition activity, said Burton. 

Other top identity management market trends pinpointed in the report included identity in service-oriented architecture (SOA) environments, and electronic information cards built around technology from the likes of Microsoft‘s CardSpace - a component of Windows Vista
