This textbook introduces new business concepts on cloud environments
such as secure, scalable anonymity and practical payment protocols for
the Internet of things and Blockchain technology. The protocol uses
electronic cash for payment transactions. In this new protocol, from the
viewpoint of banks, consumers can improve anonymity if they are worried
about disclosure of their identities in the cloud. Currently, there is
not a book available that has reported the techniques covering the
protocols with anonymizations and Blockchain technology. Thus this will
be a useful book for universities to purchase.
This textbook provides new direction for access control management and
online business, with new challenges within Blockchain technology that
may arise in cloud environments. One is related to the authorization
granting process. For example, when a role is granted to a user, this
role may conflict with other roles of the user or together with this
role; the user may have or derive a high level of authority. Another is
related to authorization revocation. For instance, when a role is
revoked from a user, the user may still have the role. Experts will get
benefits from these challenges through the developed methodology for
authorization granting algorithm, and weak revocation and strong
revocation algorithms.
