Towards identity management for e-services

Nowadays, business and recreational activities are increasingly based on the use of remote resources and e-services, and on the interaction between different, remotely located parties. In such a context, it is of paramount importance that electronic execution of private and/or sensitive transactions fully preserves information privacy, managing in a trustworthy and responsible way all identity and profile information to be released to remote parties. In this paper, we investigate some problems concerning identity management for e-services and outline the next-generation identity management systems comparing them with today's Public Key Infrastructure (PKI) solutions.
