A lack of trust in online-transactions has been described as one of the most important obstacles for the development of e-business. Despite numerous activities in the fields of law and security, users have not yet gained the trust necessary for conducting e-business. This requires a new approach which is able to explain the importance and function of trust in the digital world. This book presents a new model of digital trust that is complemented by articles on law, security, business models and trust building signals. The book is published in a mixed German/English edition and is the first international reader covering trust and e-business from a multi-disciplinary approach.
