The document discusses key opportunities and challenges for the next generation internet (NGI) around identity, anonymity, and trust. It identifies two priorities: enabling identity to guarantee who or what someone claims to be, and enabling anonymity to guarantee only minimum information is revealed. Solutions around data and identity management are discussed, along with technologies driving the NGI like pervasive connectivity, the web as an applications platform, and cloud computing. The NGI is seen as co-evolving with society in a way that requires considering both technological and social factors.
