The last years have seen an increasing attention on privacy-aware technologies and mechanisms for the negotiation of private information between customers and enterprises. Unfortunately, current proposals are still unsatisfactory since they do not cover the entire spectrum of privacy management. Moreover, they do not provide support for emerging business models such as the inter-organizational business process (also known as virtual organizations). In this paper the authors propose a privacy model complying with the minimal disclosure principle when a coalition of organizations integrates their efforts to provide services to customers.
