BBC News reports that IBM researchers in Zurich are working on an EU funded project called Attribute-Based Credentials for Trust (ABC4Trust) which encrypts all personal information in a personal privacy wallet.

From the description on the project blog the design of a seed is very similar to the ‘Privacy Butler’ architecture proposed by the PRiMMA team, and the Personal Data Vault (PDV) idea proposed by researchers at UCLA.

Mobile Social Networking

Facebook has recently become the leading social networking application, offering a wealth of functionalities and allowing users to share both information and artifacts.
