The Liberty Alliance trade group has taken on several new members, bringing membership of the three-year-old organisation to more than 150 companies.
Oracle and Sharp Laboratories of America are among the latest signings, joining others such as Intel and Computer Associates International which have recently come on board.
"The momentum shows that the industry is recognising the contribution we're making," said Simon Nicholson, chair of the Liberty Alliance's business and marketing group.
The Liberty Alliance develops and promotes open specifications for managing user identities on networks. The group's goal is to enable secure interoperability across heterogeneous systems.
Several companies now release commercial products compliant with the group's framework, though participating service providers are still in the early phases of their deployment plans. To illustrate its progress, the Liberty Alliance has organised member demonstrationsat the Burton Group's Catalyst conference in San Diego.
Participant Vodafone plans to show off a service allowing users to log on to Vodafone's portal website, find a photo-printing service and arrange for photos to be printed and shipped. Based on a user's privacy settings, the service will hand various pieces of information to the selected third-party printing company.
That service is one of several Vodafone expects to go live next year, when it rolls out a new set of web services across its product lines, according to Vodafone senior strategy manager James Vanderbeek.
