The everyday use of electronic services has increased significantly. For the enforcement of these transactions customers have to manage many different accounts in different service providers. The consequence of this action, is the customer's personal data exposure which is inevitable. Taking this into account, we find out how important the protection of our privacy is, because with this trend our privacy is lost. There is a solution to this big issue and is called Anonymous Credential. Anonymous Credential Systems promise that they can change this situation and provide privacy and strong authentication. Nevertheless, the biggest disadvantage of the Anonymous Credentials is that these are still under research and they are very complex and not so understandable to the readers who are not researchers or experts in the domain of cryptography and mathematics. In this master thesis, our key goal is to provide a way so that the Anonymous Credential become more understandable to more people than before. Also, we demonstrate a new project which has as key goal the support of Anonymous Credential to their customers for their online and other transactions. Furthermore, we represent two use cases which will explain in detail how the Anonymous Credential will be used in real-life.
