Query: Proposed E-payment Process Model to Enhance Quality of Service through
  Maintaining the Trust of Availability   The use of the Internet has become an urgent necessity in various fields and
activities. One of such important fields could be electronic business
(E-Business). E-business includes all operations and activities related to
Internet commerce, including e-commerce, e-marketing, eservices, e-payment, and
electronic transfer. This proposal focuses on two perspectives that are under
e-commerce umbrella where many e-payment process models suffer from the lack of
clarity in the special procedures of the verification of the quality of
services. This proposal, therefore, proposes a new E-payment process model to
enhance the quality of service through maintaining availability. The proposed
model focuses on the concepts of electronic payment model dimensions, which
includes integrity, non-repudiation, authenticity, confidentiality, privacy,
and availability. Accordingly, the proposed model implements the availability
dimension in order to improve the quality of services that are provided to the
consumer.
